Member Function Documentation
◆ AbortMultipartUpload()
|
virtual |
This action aborts a multipart upload. After a multipart upload is aborted, no additional parts can be uploaded using that upload ID. The storage consumed by any previously uploaded parts will be freed. However, if any part uploads are currently in progress, those part uploads might or might not succeed. As a result, it might be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts.
To verify that all parts have been removed, so you don't get charged for the part storage, you should call the ListParts action and ensure that the parts list is empty.
For information about permissions required to use the multipart upload, see Multipart Upload and Permissions.
The following operations are related to AbortMultipartUpload:
See Also:
◆ AbortMultipartUploadAsync()
|
virtual |
An Async wrapper for AbortMultipartUpload that queues the request into a thread executor and triggers associated callback when operation has finished.
◆ AbortMultipartUploadCallable()
|
virtual |
A Callable wrapper for AbortMultipartUpload that returns a future to the operation so that it can be executed in parallel to other requests.
◆ accessEndpointProvider()
| std::shared_ptr< S3EndpointProviderBase > & Aws::S3::S3Client::accessEndpointProvider | ( | ) |
◆ CompleteMultipartUpload()
|
virtual |
Completes a multipart upload by assembling previously uploaded parts.
You first initiate the multipart upload and then upload all parts using the UploadPart operation. After successfully uploading all relevant parts of an upload, you call this action to complete the upload. Upon receiving this request, Amazon S3 concatenates all the parts in ascending order by part number to create a new object. In the Complete Multipart Upload request, you must provide the parts list. You must ensure that the parts list is complete. This action concatenates the parts that you provide in the list. For each part in the list, you must provide the part number and the ETag value, returned after that part was uploaded.
Processing of a Complete Multipart Upload request could take several minutes to complete. After Amazon S3 begins processing the request, it sends an HTTP response header that specifies a 200 OK response. While processing is in progress, Amazon S3 periodically sends white space characters to keep the connection from timing out. Because a request could fail after the initial 200 OK response has been sent, it is important that you check the response body to determine whether the request succeeded.
Note that if CompleteMultipartUpload fails, applications should be prepared to retry the failed requests. For more information, see Amazon S3 Error Best Practices.
You cannot use Content-Type: application/x-www-form-urlencoded with Complete Multipart Upload requests. Also, if you do not provide a Content-Type header, CompleteMultipartUpload returns a 200 OK response.
For more information about multipart uploads, see Uploading Objects Using Multipart Upload.
For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions.
CompleteMultipartUpload has the following special errors:
-
Error code:
EntityTooSmall-
Description: Your proposed upload is smaller than the minimum allowed object size. Each part must be at least 5 MB in size, except the last part.
-
400 Bad Request
-
-
Error code:
InvalidPart-
Description: One or more of the specified parts could not be found. The part might not have been uploaded, or the specified entity tag might not have matched the part's entity tag.
-
400 Bad Request
-
-
Error code:
InvalidPartOrder-
Description: The list of parts was not in ascending order. The parts list must be specified in order by part number.
-
400 Bad Request
-
-
Error code:
NoSuchUpload-
Description: The specified multipart upload does not exist. The upload ID might be invalid, or the multipart upload might have been aborted or completed.
-
404 Not Found
-
The following operations are related to CompleteMultipartUpload:
See Also:
◆ CompleteMultipartUploadAsync()
|
virtual |
An Async wrapper for CompleteMultipartUpload that queues the request into a thread executor and triggers associated callback when operation has finished.
◆ CompleteMultipartUploadCallable()
|
virtual |
A Callable wrapper for CompleteMultipartUpload that returns a future to the operation so that it can be executed in parallel to other requests.
◆ CopyObject()
|
virtual |
Creates a copy of an object that is already stored in Amazon S3.
You can store individual objects of up to 5 TB in Amazon S3. You create a copy of your object up to 5 GB in size in a single atomic action using this API. However, to copy an object greater than 5 GB, you must use the multipart upload Upload Part - Copy (UploadPartCopy) API. For more information, see Copy Object Using the REST Multipart Upload API.
All copy requests must be authenticated. Additionally, you must have read access to the source object and write access to the destination bucket. For more information, see REST Authentication. Both the Region that you want to copy the object from and the Region that you want to copy the object to must be enabled for your account.
A copy request might return an error when Amazon S3 receives the copy request or while Amazon S3 is copying the files. If the error occurs before the copy action starts, you receive a standard Amazon S3 error. If the error occurs during the copy operation, the error response is embedded in the 200 OK response. This means that a 200 OK response can contain either a success or an error. Design your application to parse the contents of the response and handle it appropriately.
If the copy is successful, you receive a response with information about the copied object.
If the request is an HTTP 1.1 request, the response is chunk encoded. If it were not, it would not contain the content-length, and you would need to read the entire body.
The copy request charge is based on the storage class and Region that you specify for the destination object. For pricing information, see Amazon S3 pricing.
Amazon S3 transfer acceleration does not support cross-Region copies. If you request a cross-Region copy using a transfer acceleration endpoint, you get a 400 Bad Request error. For more information, see Transfer Acceleration.
Metadata
When copying an object, you can preserve all metadata (default) or specify new metadata. However, the ACL is not preserved and is set to private for the user making the request. To override the default ACL setting, specify a new ACL when generating a copy request. For more information, see Using ACLs.
To specify whether you want the object metadata copied from the source object or replaced with metadata provided in the request, you can optionally add the x-amz-metadata-directive header. When you grant permissions, you can use the s3:x-amz-metadata-directive condition key to enforce certain metadata behavior when objects are uploaded. For more information, see Specifying Conditions in a Policy in the Amazon S3 User Guide. For a complete list of Amazon S3-specific condition keys, see Actions, Resources, and Condition Keys for Amazon S3.
x-amz-copy-source-if Headers
To only copy an object under certain conditions, such as whether the Etag matches or whether the object was modified before or after a specified date, use the following request parameters:
-
x-amz-copy-source-if-match -
x-amz-copy-source-if-none-match -
x-amz-copy-source-if-unmodified-since -
x-amz-copy-source-if-modified-since
If both the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request and evaluate as follows, Amazon S3 returns 200 OK and copies the data:
-
x-amz-copy-source-if-matchcondition evaluates to true -
x-amz-copy-source-if-unmodified-sincecondition evaluates to false
If both the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request and evaluate as follows, Amazon S3 returns the 412 Precondition Failed response code:
-
x-amz-copy-source-if-none-matchcondition evaluates to false -
x-amz-copy-source-if-modified-sincecondition evaluates to true
All headers with the x-amz- prefix, including x-amz-copy-source, must be signed.
Server-side encryption
When you perform a CopyObject operation, you can optionally use the appropriate encryption-related headers to encrypt the object using server-side encryption with Amazon Web Services managed encryption keys (SSE-S3 or SSE-KMS) or a customer-provided encryption key. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. For more information about server-side encryption, see Using Server-Side Encryption.
If a target object uses SSE-KMS, you can enable an S3 Bucket Key for the object. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide.
Access Control List (ACL)-Specific Request Headers
When copying an object, you can optionally use headers to grant ACL-based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API.
If the bucket that you're copying objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format.
For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide.
If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.
Checksums
When copying an object, if it has a checksum, that checksum will be copied to the new object by default. When you copy the object over, you may optionally specify a different checksum algorithm to use with the x-amz-checksum-algorithm header.
Storage Class Options
You can use the CopyObject action to change the storage class of an object that is already stored in Amazon S3 using the StorageClass parameter. For more information, see Storage Classes in the Amazon S3 User Guide.
Versioning
By default, x-amz-copy-source identifies the current version of an object to copy. If the current version is a delete marker, Amazon S3 behaves as if the object was deleted. To copy a different version, use the versionId subresource.
If you enable versioning on the target bucket, Amazon S3 generates a unique version ID for the object being copied. This version ID is different from the version ID of the source object. Amazon S3 returns the version ID of the copied object in the x-amz-version-id response header in the response.
If you do not enable versioning or suspend it on the target bucket, the version ID that Amazon S3 generates is always null.
If the source object's storage class is GLACIER, you must restore a copy of this object before you can use it as a source object for the copy operation. For more information, see RestoreObject.
The following operations are related to CopyObject:
For more information, see Copying Objects.
See Also:
◆ CopyObjectAsync()
|
virtual |
An Async wrapper for CopyObject that queues the request into a thread executor and triggers associated callback when operation has finished.
◆ CopyObjectCallable()
|
virtual |
A Callable wrapper for CopyObject that returns a future to the operation so that it can be executed in parallel to other requests.
◆ CreateBucket()
|
virtual |
Creates a new S3 bucket. To create a bucket, you must register with Amazon S3 and have a valid Amazon Web Services Access Key ID to authenticate requests. Anonymous requests are never allowed to create buckets. By creating the bucket, you become the bucket owner.
Not every string is an acceptable bucket name. For information about bucket naming restrictions, see Bucket naming rules.
If you want to create an Amazon S3 on Outposts bucket, see Create Bucket.
By default, the bucket is created in the US East (N. Virginia) Region. You can optionally specify a Region in the request body. You might choose a Region to optimize latency, minimize costs, or address regulatory requirements. For example, if you reside in Europe, you will probably find it advantageous to create buckets in the Europe (Ireland) Region. For more information, see Accessing a bucket.
If you send your create bucket request to the s3.amazonaws.com endpoint, the request goes to the us-east-1 Region. Accordingly, the signature calculations in Signature Version 4 must use us-east-1 as the Region, even if the location constraint in the request specifies another Region where the bucket is to be created. If you create a bucket in a Region other than US East (N. Virginia), your application must be able to handle 307 redirect. For more information, see Virtual hosting of buckets.
Access control lists (ACLs)
When creating a bucket using this operation, you can optionally configure the bucket ACL to specify the accounts or groups that should be granted specific permissions on the bucket.
If your CreateBucket request sets bucket owner enforced for S3 Object Ownership and specifies a bucket ACL that provides access to an external Amazon Web Services account, your request fails with a 400 error and returns the InvalidBucketAclWithObjectOwnership error code. For more information, see Controlling object ownership in the Amazon S3 User Guide.
There are two ways to grant the appropriate permissions using the request headers.
-
Specify a canned ACL using the
x-amz-aclrequest header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL. -
Specify access permissions explicitly using the
x-amz-grant-read,x-amz-grant-write,x-amz-grant-read-acp,x-amz-grant-write-acp, andx-amz-grant-full-controlheaders. These headers map to the set of permissions Amazon S3 supports in an ACL. For more information, see Access control list (ACL) overview.You specify each grantee as a type=value pair, where the type is one of the following:
-
id– if the value specified is the canonical user ID of an Amazon Web Services account -
uri– if you are granting permissions to a predefined group -
emailAddress– if the value specified is the email address of an Amazon Web Services accountUsing email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:
-
US East (N. Virginia)
-
US West (N. California)
-
US West (Oregon)
-
Asia Pacific (Singapore)
-
Asia Pacific (Sydney)
-
Asia Pacific (Tokyo)
-
Europe (Ireland)
-
South America (São Paulo)
For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.
-
For example, the following
x-amz-grant-readheader grants the Amazon Web Services accounts identified by account IDs permissions to read object data and its metadata:x-amz-grant-read: id="11112222333", id="444455556666" -
You can use either a canned ACL or specify access permissions explicitly. You cannot do both.
Permissions
In addition to s3:CreateBucket, the following permissions are required when your CreateBucket includes specific headers:
-
ACLs - If your
CreateBucketrequest specifies ACL permissions and the ACL is public-read, public-read-write, authenticated-read, or if you specify access permissions explicitly through any other ACL, boths3:CreateBucketands3:PutBucketAclpermissions are needed. If the ACL theCreateBucketrequest is private or doesn't specify any ACLs, onlys3:CreateBucketpermission is needed. -
Object Lock - If
ObjectLockEnabledForBucketis set to true in yourCreateBucketrequest,s3:PutBucketObjectLockConfigurationands3:PutBucketVersioningpermissions are required. -
S3 Object Ownership - If your CreateBucket request includes the the
x-amz-object-ownershipheader,s3:PutBucketOwnershipControlspermission is required.
The following operations are related to CreateBucket:

◆ CreateBucketAsync()

◆ CreateBucketCallable()
|
virtual |
A Callable wrapper for CreateBucket that returns a future to the operation so that it can be executed in parallel to other requests.
◆ CreateMultipartUpload()
|
virtual |
This action initiates a multipart upload and returns an upload ID. This upload ID is used to associate all of the parts in the specific multipart upload. You specify this upload ID in each of your subsequent upload part requests (see UploadPart). You also include this upload ID in the final request to either complete or abort the multipart upload request.
For more information about multipart uploads, see Multipart Upload Overview.
If you have configured a lifecycle rule to abort incomplete multipart uploads, the upload must complete within the number of days specified in the bucket lifecycle configuration. Otherwise, the incomplete multipart upload becomes eligible for an abort action and Amazon S3 aborts the multipart upload. For more information, see Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Policy.
For information about the permissions required to use the multipart upload API, see Multipart Upload and Permissions.
For request signing, multipart upload is just a series of regular requests. You initiate a multipart upload, send one or more requests to upload parts, and then complete the multipart upload process. You sign each request individually. There is nothing special about signing multipart upload requests. For more information about signing, see Authenticating Requests (Amazon Web Services Signature Version 4).
After you initiate a multipart upload and upload one or more parts, to stop being charged for storing the uploaded parts, you must either complete or abort the multipart upload. Amazon S3 frees up the space used to store the parts and stop charging you for storing them only after you either complete or abort a multipart upload.
You can optionally request server-side encryption. For server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. You can provide your own encryption key, or use Amazon Web Services KMS keys or Amazon S3-managed encryption keys. If you choose to provide your own encryption key, the request headers you provide in UploadPart and UploadPartCopy requests must match the headers you used in the request to initiate the upload by using CreateMultipartUpload.
To perform a multipart upload with encryption using an Amazon Web Services KMS key, the requester must have permission to the kms:Decrypt and kms:GenerateDataKey* actions on the key. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload. For more information, see Multipart upload API and permissions in the Amazon S3 User Guide.
If your Identity and Access Management (IAM) user or role is in the same Amazon Web Services account as the KMS key, then you must have these permissions on the key policy. If your IAM user or role belongs to a different account than the key, then you must have the permissions on both the key policy and your IAM user or role.
For more information, see Protecting Data Using Server-Side Encryption.
- Access Permissions
-
When copying an object, you can optionally specify the accounts or groups that should be granted specific permissions on the new object. There are two ways to grant the permissions using the request headers:
-
Specify a canned ACL with the
x-amz-aclrequest header. For more information, see Canned ACL. -
Specify access permissions explicitly with the
x-amz-grant-read,x-amz-grant-read-acp,x-amz-grant-write-acp, andx-amz-grant-full-controlheaders. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview.
You can use either a canned ACL or specify access permissions explicitly. You cannot do both.
-
- Server-Side- Encryption-Specific Request Headers
-
You can optionally tell Amazon S3 to encrypt data at rest using server-side encryption. Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. The option you use depends on whether you want to use Amazon Web Services managed encryption keys or provide your own encryption key.
-
Use encryption keys managed by Amazon S3 or customer managed key stored in Amazon Web Services Key Management Service (Amazon Web Services KMS) – If you want Amazon Web Services to manage the keys used to encrypt data, specify the following headers in the request.
-
x-amz-server-side-encryption -
x-amz-server-side-encryption-aws-kms-key-id -
x-amz-server-side-encryption-context
If you specify
x-amz-server-side-encryption:aws:kms, but don't providex-amz-server-side-encryption-aws-kms-key-id, Amazon S3 uses the Amazon Web Services managed key in Amazon Web Services KMS to protect the data.All GET and PUT requests for an object protected by Amazon Web Services KMS fail if you don't make them with SSL or by using SigV4.
For more information about server-side encryption with KMS key (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys.
-
-
Use customer-provided encryption keys – If you want to manage your own encryption keys, provide all the following headers in the request.
-
x-amz-server-side-encryption-customer-algorithm -
x-amz-server-side-encryption-customer-key -
x-amz-server-side-encryption-customer-key-MD5
For more information about server-side encryption with KMS keys (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys.
-
-
- Access-Control-List (ACL)-Specific Request Headers
-
You also can use the following access control–related headers with this operation. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the access control list (ACL) on the object. For more information, see Using ACLs. With this operation, you can grant access permissions using one of the following two methods:
-
Specify a canned ACL (
x-amz-acl) — Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL. -
Specify access permissions explicitly — To explicitly grant access permissions to specific Amazon Web Services accounts or groups, use the following headers. Each header maps to specific permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview. In the header, you specify a list of grantees who get the specific permission. To grant permissions explicitly, use:
-
x-amz-grant-read -
x-amz-grant-write -
x-amz-grant-read-acp -
x-amz-grant-write-acp -
x-amz-grant-full-control
You specify each grantee as a type=value pair, where the type is one of the following:
-
id– if the value specified is the canonical user ID of an Amazon Web Services account -
uri– if you are granting permissions to a predefined group -
emailAddress– if the value specified is the email address of an Amazon Web Services accountUsing email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:
-
US East (N. Virginia)
-
US West (N. California)
-
US West (Oregon)
-
Asia Pacific (Singapore)

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities.
The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class.

◆ DeleteBucketPolicy()
|
virtual |
This implementation of the DELETE action uses the policy subresource to delete the policy of a specified bucket. If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must have the DeleteBucketPolicy permissions on the specified bucket and belong to the bucket owner's account to use this operation.
If you don't have DeleteBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.
As a security precaution, the root user of the Amazon Web Services account that owns a bucket can always use this operation, even if the policy explicitly denies the root user the ability to perform this action.
For more information about bucket policies, see Using Bucket Policies and UserPolicies.

◆ DeleteBucketWebsite()
|
virtual |
This action removes the website configuration for a bucket. Amazon S3 returns a 200 OK response upon successfully deleting a website configuration on the specified bucket. You will get a 200 OK response if the website configuration you are trying to delete does not exist on the bucket. Amazon S3 returns a 404 response if the bucket specified in the request does not exist.
This DELETE action requires the S3:DeleteBucketWebsite permission. By default, only the bucket owner can delete the website configuration attached to a bucket. However, bucket owners can grant other users permission to delete the website configuration by writing a bucket policy granting them the S3:DeleteBucketWebsite permission.

◆ DeleteObject()
|
virtual |
Removes the null version (if there is one) of an object and inserts a delete marker, which becomes the latest version of the object. If there isn't a null version, Amazon S3 does not remove any objects but will still respond that the command was successful.
To remove a specific version, you must be the bucket owner and you must use the version Id subresource. Using this subresource permanently deletes the version. If the object deleted is a delete marker, Amazon S3 sets the response header, x-amz-delete-marker, to true.
If the object you want to delete is in a bucket where the bucket versioning configuration is MFA Delete enabled, you must include the x-amz-mfa request header in the DELETE versionId request. Requests that include x-amz-mfa must use HTTPS.
For more information about MFA Delete, see Using MFA Delete. To see sample requests that use versioning, see Sample Request.
You can delete objects by explicitly calling DELETE Object or configure its lifecycle (PutBucketLifecycle) to enable Amazon S3 to remove them for you. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them the s3:DeleteObject, s3:DeleteObjectVersion, and s3:PutLifeCycleConfiguration actions.
The following action is related to DeleteObject:

◆ DeleteObjects()
|
virtual |
This action enables you to delete multiple objects from a bucket using a single HTTP request. If you know the object keys that you want to delete, then this action provides a suitable alternative to sending individual delete requests, reducing per-request overhead.
The request contains a list of up to 1000 keys that you want to delete. In the XML, you provide the object key names, and optionally, version IDs if you want to delete a specific version of the object from a versioning-enabled bucket. For each key, Amazon S3 performs a delete action and returns the result of that delete, success, or failure, in the response. Note that if the object specified in the request is not found, Amazon S3 returns the result as deleted.
The action supports two modes for the response: verbose and quiet. By default, the action uses verbose mode in which the response includes the result of deletion of each key in your request. In quiet mode the response includes only keys where the delete action encountered an error. For a successful deletion, the action does not return any information about the delete in the response body.
When performing this action on an MFA Delete enabled bucket, that attempts to delete any versioned objects, you must include an MFA token. If you do not provide one, the entire request will fail, even if there are non-versioned objects you are trying to delete. If you provide an invalid token, whether there are versioned keys in the request or not, the entire Multi-Object Delete request will fail. For information about MFA Delete, see MFA Delete.
Finally, the Content-MD5 header is required for all Multi-Object Delete requests. Amazon S3 uses the header value to ensure that your request body has not been altered in transit.

◆ GetBucketAccelerateConfiguration()
|
virtual |
This implementation of the GET action uses the accelerate subresource to return the Transfer Acceleration state of a bucket, which is either Enabled or Suspended. Amazon S3 Transfer Acceleration is a bucket-level feature that enables you to perform faster data transfers to and from Amazon S3.
To use this operation, you must have permission to perform the s3:GetAccelerateConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to your Amazon S3 Resources in the Amazon S3 User Guide.
You set the Transfer Acceleration state of an existing bucket to Enabled or Suspended by using the PutBucketAccelerateConfiguration operation.
A GET accelerate request does not return a state value for a bucket that has no transfer acceleration state. A bucket has no Transfer Acceleration state if a state has never been set on the bucket.
For more information about transfer acceleration, see Transfer Acceleration in the Amazon S3 User Guide.

◆ GetObject()
|
virtual |
Retrieves objects from Amazon S3. To use GET, you must have READ access to the object. If you grant READ access to the anonymous user, you can return the object without using an authorization header.
An Amazon S3 bucket has no directory hierarchy such as you would find in a typical computer file system. You can, however, create a logical hierarchy by using object key names that imply a folder structure. For example, instead of naming an object sample.jpg, you can name it photos/2006/February/sample.jpg.
To get an object from such a logical hierarchy, specify the full key name for the object in the GET operation. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg, specify the resource as /photos/2006/February/sample.jpg. For a path-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named examplebucket, specify the resource as /examplebucket/photos/2006/February/sample.jpg. For more information about request types, see HTTP Host Header Bucket Specification.
For more information about returning the ACL of an object, see GetObjectAcl.
If the object you are retrieving is stored in the S3 Glacier or S3 Glacier Deep Archive storage class, or S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers, before you can retrieve the object you must first restore a copy using RestoreObject. Otherwise, this action returns an InvalidObjectStateError error. For information about restoring archived objects, see Restoring Archived Objects.
Encryption request headers, like x-amz-server-side-encryption, should not be sent for GET requests if your object uses server-side encryption with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.
If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you GET the object, you must use the following headers:
-
x-amz-server-side-encryption-customer-algorithm
-
x-amz-server-side-encryption-customer-key
-
x-amz-server-side-encryption-customer-key-MD5
For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys).
Assuming you have the relevant permission to read object tags, the response also returns the x-amz-tagging-count header that provides the count of number of tags associated with the object. You can use GetObjectTagging to retrieve the tag set associated with an object.
Permissions
You need the relevant read object (or version) permission for this operation. For more information, see Specifying Permissions in a Policy. If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.
-
If you have the
s3:ListBucketpermission on the bucket, Amazon S3 will return an HTTP status code 404 ("no such key") error. -
If you don’t have the
s3:ListBucketpermission, Amazon S3 will return an HTTP status code 403 ("access denied") error.
Versioning
By default, the GET action returns the current version of an object. To return a different version, use the versionId subresource.
-
If you supply a
versionId, you need thes3:GetObjectVersionpermission to access a specific version of an object. If you request a specific version, you do not need to have thes3:GetObjectpermission. -
If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes
x-amz-delete-marker: truein the response.
For more information about versioning, see PutBucketVersioning.
Overriding Response Header Values
There are times when you want to override certain response header values in a GET response. For example, you might override the Content-Disposition response header value in your GET request.
You can override values for a set of response headers using the following query parameters. These response header values are sent only on a successful request, that is, when status code 200 OK is returned. The set of headers you can override using these parameters is a subset of the headers that Amazon S3 accepts when you create an object. The response headers that you can override for the GET response are Content-Type, Content-Language, Expires, Cache-Control, Content-Disposition, and Content-Encoding. To override these header values in the GET response, you use the following request parameters.
You must sign the request, either using an Authorization header or a presigned URL, when using these parameters. They cannot be used with an unsigned (anonymous) request.
-
response-content-type -
response-content-language -
response-expires -
response-cache-control -
response-content-disposition -
response-content-encoding
Additional Considerations about Request Headers
If both of the If-Match and If-Unmodified-Since headers are present in the request as follows: If-Match condition evaluates to true, and; If-Unmodified-Since condition evaluates to false; then, S3 returns 200 OK and the data requested.
If both of the If-None-Match and If-Modified-Since headers are present in the request as follows: If-None-Match condition evaluates to false, and; If-Modified-Since condition evaluates to true; then, S3 returns 304 Not Modified response code.
For more information about conditional requests, see RFC 7232.
The following operations are related to GetObject:
See Also:
◆ GetObjectAcl()
|
virtual |
Returns the access control list (ACL) of an object. To use this operation, you must have s3:GetObjectAcl permissions or READ_ACP access to the object. For more information, see Mapping of ACL permissions and access policy permissions in the Amazon S3 User Guide
This action is not supported by Amazon S3 on Outposts.
Versioning
By default, GET returns ACL information about the current version of an object. To return ACL information about a different version, use the versionId subresource.
If your bucket uses the bucket owner enforced setting for S3 Object Ownership, requests to read ACLs are still supported and return the bucket-owner-full-control ACL with the owner being the account that created the bucket. For more information, see Controlling object ownership and disabling ACLs in the Amazon S3 User Guide.
The following operations are related to GetObjectAcl:
See Also:
◆ GetObjectAclAsync()
|
virtual |
An Async wrapper for GetObjectAcl that queues the request into a thread executor and triggers associated callback when operation has finished.
◆ GetObjectAclCallable()
|
virtual |
A Callable wrapper for GetObjectAcl that returns a future to the operation so that it can be executed in parallel to other requests.
◆ GetObjectAsync()
|
virtual |
An Async wrapper for GetObject that queues the request into a thread executor and triggers associated callback when operation has finished.
◆ GetObjectAttributes()
|
virtual |
Retrieves all the metadata from an object without returning the object itself. This action is useful if you're interested only in an object's metadata. To use GetObjectAttributes, you must have READ access to the object.
GetObjectAttributes combines the functionality of GetObjectAcl, GetObjectLegalHold, GetObjectLockConfiguration, GetObjectRetention, GetObjectTagging, HeadObject, and ListParts. All of the data returned with each of those individual calls can be returned with a single call to GetObjectAttributes.
If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers:
-
x-amz-server-side-encryption-customer-algorithm -
x-amz-server-side-encryption-customer-key -
x-amz-server-side-encryption-customer-key-MD5
For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) in the Amazon S3 User Guide.
-
Encryption request headers, such as
x-amz-server-side-encryption, should not be sent for GET requests if your object uses server-side encryption with Amazon Web Services KMS keys stored in Amazon Web Services Key Management Service (SSE-KMS) or server-side encryption with Amazon S3 managed encryption keys (SSE-S3). If your object does use these types of keys, you'll get an HTTP400 Bad Requesterror. -
The last modified property in this case is the creation date of the object.
Consider the following when using request headers:
-
If both of the
If-MatchandIf-Unmodified-Sinceheaders are present in the request as follows, then Amazon S3 returns the HTTP status code200 OKand the data requested:-
If-Matchcondition evaluates totrue. -
If-Unmodified-Sincecondition evaluates tofalse.
-
-
If both of the
If-None-MatchandIf-Modified-Sinceheaders are present in the request as follows, then Amazon S3 returns the HTTP status code304 Not Modified:-
If-None-Matchcondition evaluates tofalse. -
If-Modified-Sincecondition evaluates totrue.
-
For more information about conditional requests, see RFC 7232.
Permissions
The permissions that you need to use this operation depend on whether the bucket is versioned. If the bucket is versioned, you need both the s3:GetObjectVersion and s3:GetObjectVersionAttributes permissions for this operation. If the bucket is not versioned, you need the s3:GetObject and s3:GetObjectAttributes permissions. For more information, see Specifying Permissions in a Policy in the Amazon S3 User Guide. If the object that you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.
-
If you have the
s3:ListBucketpermission on the bucket, Amazon S3 returns an HTTP status code404 Not Found("no such key") error. -
If you don't have the
s3:ListBucketpermission, Amazon S3 returns an HTTP status code403 Forbidden("access denied") error.

When Amazon S3 evaluates the PublicAccessBlock configuration for a bucket or an object, it checks the PublicAccessBlock configuration for both the bucket (or the bucket that contains the object) and the bucket owner's account. If the PublicAccessBlock settings are different between the bucket and the account, Amazon S3 uses the most restrictive combination of the bucket-level and account-level settings.
For more information about when Amazon S3 considers a bucket or an object public, see The Meaning of "Public".
The following operations are related to GetPublicAccessBlock:

◆ HeadBucket()
|
virtual |
This action is useful to determine if a bucket exists and you have permission to access it. The action returns a 200 OK if the bucket exists and you have permission to access it.
If the bucket does not exist or you do not have permission to access it, the HEAD request returns a generic 404 Not Found or 403 Forbidden code. A message body is not included, so you cannot determine the exception beyond these error codes.
To use this operation, you must have permissions to perform the s3:ListBucket action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources.
To use this API against an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using the Amazon Web Services SDKs, you provide the ARN in place of the bucket name. For more information see, Using access points.

◆ HeadBucketCallable()
|
virtual |
A Callable wrapper for HeadBucket that returns a future to the operation so that it can be executed in parallel to other requests.
◆ HeadObject()
|
virtual |
The HEAD action retrieves metadata from an object without returning the object itself. This action is useful if you're only interested in an object's metadata. To use HEAD, you must have READ access to the object.
A HEAD request has the same options as a GET action on an object. The response is identical to the GET response except that there is no response body. Because of this, if the HEAD request generates an error, it returns a generic 404 Not Found or 403 Forbidden code. It is not possible to retrieve the exact exception beyond these error codes.
If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers:
-
x-amz-server-side-encryption-customer-algorithm
-
x-amz-server-side-encryption-customer-key
-
x-amz-server-side-encryption-customer-key-MD5
For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys).
-
Encryption request headers, like
x-amz-server-side-encryption, should not be sent for GET requests if your object uses server-side encryption with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error. -
The last modified property in this case is the creation date of the object.
Request headers are limited to 8 KB in size. For more information, see Common Request Headers.
Consider the following when using request headers:
-
Consideration 1 – If both of the
If-MatchandIf-Unmodified-Sinceheaders are present in the request as follows:-
If-Matchcondition evaluates totrue, and; -
If-Unmodified-Sincecondition evaluates tofalse;
Then Amazon S3 returns
200 OKand the data requested. -
-
Consideration 2 – If both of the
If-None-MatchandIf-Modified-Sinceheaders are present in the request as follows:-
If-None-Matchcondition evaluates tofalse, and; -
If-Modified-Sincecondition evaluates totrue;
Then Amazon S3 returns the
304 Not Modifiedresponse code. -
For more information about conditional requests, see RFC 7232.
Permissions
You need the relevant read object (or version) permission for this operation. For more information, see Specifying Permissions in a Policy. If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.
-
If you have the
s3:ListBucketpermission on the bucket, Amazon S3 returns an HTTP status code 404 ("no such key") error. -
If you don’t have the
s3:ListBucketpermission, Amazon S3 returns an HTTP status code 403 ("access denied") error.

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities.
The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class.
For more information, see Storage class for automatically optimizing frequently and infrequently accessed objects.

◆ ListMultipartUploads()
|
virtual |
This action lists in-progress multipart uploads. An in-progress multipart upload is a multipart upload that has been initiated using the Initiate Multipart Upload request, but has not yet been completed or aborted.
This action returns at most 1,000 multipart uploads in the response. 1,000 multipart uploads is the maximum number of uploads a response can include, which is also the default value. You can further limit the number of uploads in a response by specifying the max-uploads parameter in the response. If additional multipart uploads satisfy the list criteria, the response will contain an IsTruncated element with the value true. To list the additional multipart uploads, use the key-marker and upload-id-marker request parameters.
In the response, the uploads are sorted by key. If your application has initiated more than one multipart upload using the same object key, then uploads in the response are first sorted by key. Additionally, uploads are sorted in ascending order within each key by the upload initiation time.

◆ PutBucketAcl()
|
virtual |
Sets the permissions on an existing bucket using access control lists (ACL). For more information, see Using ACLs. To set the ACL of a bucket, you must have WRITE_ACP permission.
You can use one of the following two ways to set a bucket's permissions:
-
Specify the ACL in the request body
-
Specify permissions using request headers
You cannot specify access permission using both the body and the request headers.
Depending on your application needs, you may choose to set the ACL on a bucket using either the request body or the headers. For example, if you have an existing application that updates a bucket ACL using the request body, then you can continue to use that approach.
If your bucket uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. You must use policies to grant access to your bucket and the objects in it. Requests to set ACLs or update ACLs fail and return the AccessControlListNotSupported error code. Requests to read ACLs are still supported. For more information, see Controlling object ownership in the Amazon S3 User Guide.
Access Permissions
You can set access permissions using one of the following methods:
-
Specify a canned ACL with the
x-amz-aclrequest header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. Specify the canned ACL name as the value ofx-amz-acl. If you use this header, you cannot use other access control-specific headers in your request. For more information, see Canned ACL. -
Specify access permissions explicitly with the
x-amz-grant-read,x-amz-grant-read-acp,x-amz-grant-write-acp, andx-amz-grant-full-controlheaders. When using these headers, you specify explicit access permissions and grantees (Amazon Web Services accounts or Amazon S3 groups) who will receive the permission. If you use these ACL-specific headers, you cannot use thex-amz-aclheader to set a canned ACL. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview.You specify each grantee as a type=value pair, where the type is one of the following:
-
id– if the value specified is the canonical user ID of an Amazon Web Services account -
uri– if you are granting permissions to a predefined group -
emailAddress– if the value specified is the email address of an Amazon Web Services accountUsing email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:
-
US East (N. Virginia)
-
US West (N. California)
-
US West (Oregon)
-
Asia Pacific (Singapore)
-
Asia Pacific (Sydney)
-
Asia Pacific (Tokyo)
-
Europe (Ireland)
-
South America (São Paulo)
For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.
-
For example, the following
x-amz-grant-writeheader grants create, overwrite, and delete objects permission to LogDelivery group predefined by Amazon S3 and two Amazon Web Services accounts identified by their email addresses.x-amz-grant-write: uri="http://acs.amazonaws.com/groups/s3/LogDelivery", id="111122223333", id="555566667777" -
You can use either a canned ACL or specify access permissions explicitly. You cannot do both.
Grantee Values
You can specify the person (grantee) to whom you're assigning access rights (using request elements) in the following ways:
-
By the person's ID:
<Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName> </Grantee>DisplayName is optional and ignored in the request
-
By URI:
<Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Group"><URI><>http://acs.amazonaws.com/groups/global/AuthenticatedUsers<></URI></Grantee> -
By Email address:
<Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="AmazonCustomerByEmail"><EmailAddress><>Grant.nosp@m.ees@.nosp@m.email.nosp@m..com<></EmailAddress>lt;/Grantee>The grantee is resolved to the CanonicalUser and, in a response to a GET Object acl request, appears as the CanonicalUser.
Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:
-
US East (N. Virginia)
-
US West (N. California)
-
US West (Oregon)
-
Asia Pacific (Singapore)
-
Asia Pacific (Sydney)

You can choose to have storage class analysis export analysis reports sent to a comma-separated values (CSV) flat file. See the DataExport request element. Reports are updated daily and are based on the object filters that you configure. When selecting data export, you specify a destination bucket and an optional destination prefix where the file is written. You can export the data to a destination bucket in a different account. However, the destination bucket must be in the same Region as the bucket that you are making the PUT analytics configuration to. For more information, see Amazon S3 Analytics – Storage Class Analysis.
You must create a bucket policy on the destination bucket where the exported file is written to grant permissions to Amazon S3 to write objects to the bucket. For an example policy, see Granting Permissions for Amazon S3 Inventory and Storage Class Analysis.
To use this operation, you must have permissions to perform the s3:PutAnalyticsConfiguration action. The bucket owner has this permission by default.

◆ PutBucketCors()
|
virtual |
Sets the cors configuration for your bucket. If the configuration exists, Amazon S3 replaces it.
To use this operation, you must be allowed to perform the s3:PutBucketCORS action. By default, the bucket owner has this permission and can grant it to others.
You set this configuration on a bucket so that the bucket can service cross-origin requests. For example, you might want to enable a request whose origin is http://www.example.com to access your Amazon S3 bucket at my.example.bucket.com by using the browser's XMLHttpRequest capability.
To enable cross-origin resource sharing (CORS) on a bucket, you add the cors subresource to the bucket. The cors subresource is an XML document in which you configure rules that identify origins and the HTTP methods that can be executed on your bucket. The document is limited to 64 KB in size.
When Amazon S3 receives a cross-origin request (or a pre-flight OPTIONS request) against a bucket, it evaluates the cors configuration on the bucket and uses the first CORSRule rule that matches the incoming browser request to enable a cross-origin request. For a rule to match, the following conditions must be met:
-
The request's
Originheader must matchAllowedOriginelements. -
The request method (for example, GET, PUT, HEAD, and so on) or the
Access-Control-Request-Methodheader in case of a pre-flightOPTIONSrequest must be one of theAllowedMethodelements. -
Every header specified in the
Access-Control-Request-Headersrequest header of a pre-flight request must match anAllowedHeaderelement.
For more information about CORS, go to Enabling Cross-Origin Resource Sharing in the Amazon S3 User Guide.

◆ PutBucketEncryption()
|
virtual |
This action uses the encryption subresource to configure default encryption and Amazon S3 Bucket Key for an existing bucket.
Default encryption for a bucket can use server-side encryption with Amazon S3-managed keys (SSE-S3) or customer managed keys (SSE-KMS). If you specify default encryption using SSE-KMS, you can also configure Amazon S3 Bucket Key. When the default encryption is SSE-KMS, if you upload an object to the bucket and do not specify the KMS key to use for encryption, Amazon S3 uses the default Amazon Web Services managed KMS key for your account. For information about default encryption, see Amazon S3 default bucket encryption in the Amazon S3 User Guide. For more information about S3 Bucket Keys, see Amazon S3 Bucket Keys in the Amazon S3 User Guide.
This action requires Amazon Web Services Signature Version 4. For more information, see Authenticating Requests (Amazon Web Services Signature Version 4).
To use this operation, you must have permissions to perform the s3:PutEncryptionConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide.

◆ PutBucketInventoryConfiguration()
|
virtual |
This implementation of the PUT action adds an inventory configuration (identified by the inventory ID) to the bucket. You can have up to 1,000 inventory configurations per bucket.
Amazon S3 inventory generates inventories of the objects in the bucket on a daily or weekly basis, and the results are published to a flat file. The bucket that is inventoried is called the source bucket, and the bucket where the inventory flat file is stored is called the destination bucket. The destination bucket must be in the same Amazon Web Services Region as the source bucket.
When you configure an inventory for a source bucket, you specify the destination bucket where you want the inventory to be stored, and whether to generate the inventory daily or weekly. You can also configure what object metadata to include and whether to inventory all object versions or only current versions. For more information, see Amazon S3 Inventory in the Amazon S3 User Guide.
You must create a bucket policy on the destination bucket to grant permissions to Amazon S3 to write objects to the bucket in the defined location. For an example policy, see Granting Permissions for Amazon S3 Inventory and Storage Class Analysis.
To use this operation, you must have permissions to perform the s3:PutInventoryConfiguration action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide.

◆ PutBucketLifecycleConfiguration()
|
virtual |
Creates a new lifecycle configuration for the bucket or replaces an existing lifecycle configuration. Keep in mind that this will overwrite an existing lifecycle configuration, so if you want to retain any configuration details, they must be included in the new lifecycle configuration. For information about lifecycle configuration, see Managing your storage lifecycle.
Bucket lifecycle configuration now supports specifying a lifecycle rule using an object key name prefix, one or more object tags, or a combination of both. Accordingly, this section describes the latest API. The previous version of the API supported filtering based only on an object key name prefix, which is supported for backward compatibility. For the related API description, see PutBucketLifecycle.
Rules
You specify the lifecycle configuration in your request body. The lifecycle configuration is specified as XML consisting of one or more rules. An Amazon S3 Lifecycle configuration can have up to 1,000 rules. This limit is not adjustable. Each rule consists of the following:
-
Filter identifying a subset of objects to which the rule applies. The filter can be based on a key name prefix, object tags, or a combination of both.
-
Status whether the rule is in effect.
-
One or more lifecycle transition and expiration actions that you want Amazon S3 to perform on the objects identified by the filter. If the state of your bucket is versioning-enabled or versioning-suspended, you can have many versions of the same object (one current version and zero or more noncurrent versions). Amazon S3 provides predefined actions that you can specify for current and noncurrent object versions.
For more information, see Object Lifecycle Management and Lifecycle Configuration Elements.
Permissions
By default, all Amazon S3 resources are private, including buckets, objects, and related subresources (for example, lifecycle configuration and website configuration). Only the resource owner (that is, the Amazon Web Services account that created it) can access the resource. The resource owner can optionally grant access permissions to others by writing an access policy. For this operation, a user must get the s3:PutLifecycleConfiguration permission.
You can also explicitly deny permissions. Explicit deny also supersedes any other permissions. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them permissions for the following actions:
-
s3:DeleteObject -
s3:DeleteObjectVersion -
s3:PutLifecycleConfiguration
For more information about permissions, see Managing Access Permissions to Your Amazon S3 Resources.

A Callable wrapper for PutBucketLifecycleConfiguration that returns a future to the operation so that it can be executed in parallel to other requests.
◆ PutBucketLogging()
|
virtual |
Set the logging parameters for a bucket and to specify permissions for who can view and modify the logging parameters. All logs are saved to buckets in the same Amazon Web Services Region as the source bucket. To set the logging status of a bucket, you must be the bucket owner.
The bucket owner is automatically granted FULL_CONTROL to all logs. You use the Grantee request element to grant access to other people. The Permissions request element specifies the kind of access the grantee has to the logs.
If the target bucket for log delivery uses the bucket owner enforced setting for S3 Object Ownership, you can't use the Grantee request element to grant access to others. Permissions can only be granted using policies. For more information, see Permissions for server access log delivery in the Amazon S3 User Guide.
Grantee Values
You can specify the person (grantee) to whom you're assigning access rights (using request elements) in the following ways:
-
By the person's ID:
<Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName> </Grantee>DisplayName is optional and ignored in the request.
-
By Email address:
<Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="AmazonCustomerByEmail"><EmailAddress><>Grant.nosp@m.ees@.nosp@m.email.nosp@m..com<></EmailAddress></Grantee>The grantee is resolved to the CanonicalUser and, in a response to a GET Object acl request, appears as the CanonicalUser.

By URI:
<Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Group"><URI><>http://acs.amazonaws.com/groups/global/AuthenticatedUsers<></URI></Grantee>
To enable logging, you use LoggingEnabled and its children request elements. To disable logging, you use an empty BucketLoggingStatus request element:
<BucketLoggingStatus xmlns="http://doc.s3.amazonaws.com/2006-03-01" />
For more information about server access logging, see Server Access Logging in the Amazon S3 User Guide.

◆ PutBucketMetricsConfiguration()
|
virtual |
Sets a metrics configuration (specified by the metrics configuration ID) for the bucket. You can have up to 1,000 metrics configurations per bucket. If you're updating an existing metrics configuration, note that this is a full replacement of the existing metrics configuration. If you don't include the elements you want to keep, they are erased.
To use this operation, you must have permissions to perform the s3:PutMetricsConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources.

◆ PutBucketNotificationConfiguration()
|
virtual |
Enables notifications of specified events for a bucket. For more information about event notifications, see Configuring Event Notifications.
Using this API, you can replace an existing notification configuration. The configuration is an XML file that defines the event types that you want Amazon S3 to publish and the destination where you want Amazon S3 to publish an event notification when it detects an event of the specified type.
By default, your bucket has no event notifications configured. That is, the notification configuration will be an empty NotificationConfiguration.
<NotificationConfiguration>
</NotificationConfiguration>
This action replaces the existing notification configuration with the configuration you include in the request body.
After Amazon S3 receives this request, it first verifies that any Amazon Simple Notification Service (Amazon SNS) or Amazon Simple Queue Service (Amazon SQS) destination exists, and that the bucket owner has permission to publish to it by sending a test notification. In the case of Lambda destinations, Amazon S3 verifies that the Lambda function permissions grant Amazon S3 permission to invoke the function from the Amazon S3 bucket. For more information, see Configuring Notifications for Amazon S3 Events.
You can disable notifications by adding the empty NotificationConfiguration element.
For more information about the number of event notification configurations that you can create per bucket, see Amazon S3 service quotas in Amazon Web Services General Reference.
By default, only the bucket owner can configure notifications on a bucket. However, bucket owners can use a bucket policy to grant permission to other users to set this configuration with s3:PutBucketNotification permission.
The PUT notification is an atomic operation. For example, suppose your notification configuration includes SNS topic, SQS queue, and Lambda function configurations. When you send a PUT request with this configuration, Amazon S3 sends test messages to your SNS topic. If the message fails, the entire PUT action will fail, and Amazon S3 will not add the configuration to your bucket.
Responses
If the configuration in the request body includes only one TopicConfiguration specifying only the s3:ReducedRedundancyLostObject event type, the response will also include the x-amz-sns-test-message-id header containing the message ID of the test notification sent to the topic.

◆ PutBucketPolicy()
|
virtual |
Applies an Amazon S3 bucket policy to an Amazon S3 bucket. If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must have the PutBucketPolicy permissions on the specified bucket and belong to the bucket owner's account in order to use this operation.
If you don't have PutBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.
As a security precaution, the root user of the Amazon Web Services account that owns a bucket can always use this operation, even if the policy explicitly denies the root user the ability to perform this action.

◆ PutBucketReplication()
|
virtual |
Creates a replication configuration or replaces an existing one. For more information, see Replication in the Amazon S3 User Guide.
Specify the replication configuration in the request body. In the replication configuration, you provide the name of the destination bucket or buckets where you want Amazon S3 to replicate objects, the IAM role that Amazon S3 can assume to replicate objects on your behalf, and other relevant information.
A replication configuration must include at least one rule, and can contain a maximum of 1,000. Each rule identifies a subset of objects to replicate by filtering the objects in the source bucket. To choose additional subsets of objects to replicate, add a rule for each subset.
To specify a subset of the objects in the source bucket to apply a replication rule to, add the Filter element as a child of the Rule element. You can filter objects based on an object key prefix, one or more object tags, or both. When you add the Filter element in the configuration, you must also add the following elements: DeleteMarkerReplication, Status, and Priority.
If you are using an earlier version of the replication configuration, Amazon S3 handles replication of delete markers differently. For more information, see Backward Compatibility.
For information about enabling versioning on a bucket, see Using Versioning.
Handling Replication of Encrypted Objects
By default, Amazon S3 doesn't replicate objects that are stored at rest using server-side encryption with KMS keys. To replicate Amazon Web Services KMS-encrypted objects, add the following: SourceSelectionCriteria, SseKmsEncryptedObjects, Status, EncryptionConfiguration, and ReplicaKmsKeyID. For information about replication configuration, see Replicating Objects Created with SSE Using KMS keys.
For information on PutBucketReplication errors, see List of replication-related error codes
Permissions
To create a PutBucketReplication request, you must have s3:PutReplicationConfiguration permissions for the bucket.
By default, a resource owner, in this case the Amazon Web Services account that created the bucket, can perform this operation. The resource owner can also grant others permissions to perform the operation. For more information about permissions, see Specifying Permissions in a Policy and Managing Access Permissions to Your Amazon S3 Resources.
To perform this operation, the user or role performing the action must have the iam:PassRole permission.

◆ PutBucketTagging()
|
virtual |
Sets the tags for a bucket.
Use tags to organize your Amazon Web Services bill to reflect your own cost structure. To do this, sign up to get your Amazon Web Services account bill with tag key values included. Then, to see the cost of combined resources, organize your billing information according to resources with the same tag key values. For example, you can tag several resources with a specific application name, and then organize your billing information to see the total cost of that application across several services. For more information, see Cost Allocation and Tagging and Using Cost Allocation in Amazon S3 Bucket Tags.
When this operation sets the tags for a bucket, it will overwrite any current tags the bucket already has. You cannot use this operation to add tags to an existing list of tags.
To use this operation, you must have permissions to perform the s3:PutBucketTagging action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources.
PutBucketTagging has the following special errors:
-
Error code:
InvalidTagError-

◆ PutBucketVersioning()
|
virtual |
Sets the versioning state of an existing bucket.
You can set the versioning state with one of the following values:
Enabled—Enables versioning for the objects in the bucket. All objects added to the bucket receive a unique version ID.
Suspended—Disables versioning for the objects in the bucket. All objects added to the bucket receive the version ID null.
If the versioning state has never been set on a bucket, it has no versioning state; a GetBucketVersioning request does not return a versioning state value.
In order to enable MFA Delete, you must be the bucket owner. If you are the bucket owner and want to enable MFA Delete in the bucket versioning configuration, you must include the x-amz-mfa request header and the Status and the MfaDelete request elements in a request to set the versioning state of the bucket.
If you have an object expiration lifecycle policy in your non-versioned bucket and you want to maintain the same permanent delete behavior when you enable versioning, you must add a noncurrent expiration policy. The noncurrent expiration lifecycle policy will manage the deletes of the noncurrent object versions in the version-enabled bucket. (A version-enabled bucket maintains one current and zero or more noncurrent object versions.) For more information, see Lifecycle and Versioning.

◆ PutBucketWebsite()
|
virtual |
Sets the configuration of the website that is specified in the website subresource. To configure a bucket as a website, you can add this subresource on the bucket with website configuration information such as the file name of the index document and any redirect rules. For more information, see Hosting Websites on Amazon S3.
This PUT action requires the S3:PutBucketWebsite permission. By default, only the bucket owner can configure the website attached to a bucket; however, bucket owners can allow other users to set the website configuration by writing a bucket policy that grants them the S3:PutBucketWebsite permission.
To redirect all website requests sent to the bucket's website endpoint, you add a website configuration with the following elements. Because all requests are sent to another website, you don't need to provide index document name for the bucket.
-
WebsiteConfiguration -
RedirectAllRequestsTo -
HostName -
Protocol
If you want granular control over redirects, you can use the following elements to add routing rules that describe conditions for redirecting requests and information about the redirect destination. In this case, the website configuration must provide an index document for the bucket, because some requests might not be redirected.
-
WebsiteConfiguration -
IndexDocument -
Suffix -

◆ PutObject()
|
virtual |
Adds an object to a bucket. You must have WRITE permissions on a bucket to add an object to it.
Amazon S3 never adds partial objects; if you receive a success response, Amazon S3 added the entire object to the bucket.
Amazon S3 is a distributed system. If it receives multiple write requests for the same object simultaneously, it overwrites all but the last object written. Amazon S3 does not provide object locking; if you need this, make sure to build it into your application layer or use versioning instead.
To ensure that data is not corrupted traversing the network, use the Content-MD5 header. When you use this header, Amazon S3 checks the object against the provided MD5 value and, if they do not match, returns an error. Additionally, you can calculate the MD5 while putting an object to Amazon S3 and compare the returned ETag to the calculated MD5 value.
-
To successfully complete the
PutObjectrequest, you must have thes3:PutObjectin your IAM permissions. -
To successfully change the objects acl of your
PutObjectrequest, you must have thes3:PutObjectAclin your IAM permissions. -
The
Content-MD5header is required for any request to upload an object with a retention period configured using Amazon S3 Object Lock. For more information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview in the Amazon S3 User Guide.
Server-side Encryption
You can optionally request server-side encryption. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. You have the option to provide your own encryption key or use Amazon Web Services managed encryption keys (SSE-S3 or SSE-KMS). For more information, see Using Server-Side Encryption.
If you request server-side encryption using Amazon Web Services Key Management Service (SSE-KMS), you can enable an S3 Bucket Key at the object-level. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide.
Access Control List (ACL)-Specific Request Headers
You can use headers to grant ACL- based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API.
If the bucket that you're uploading objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format. PUT requests that contain other ACLs (for example, custom grants to certain Amazon Web Services accounts) fail and return a 400 error with the error code AccessControlListNotSupported.
For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide.
If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.
Storage Class Options
By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. Amazon S3 on Outposts only uses the OUTPOSTS Storage Class. For more information, see Storage Classes in the Amazon S3 User Guide.
Versioning
If you enable versioning for a bucket, Amazon S3 automatically generates a unique version ID for the object being stored. Amazon S3 returns this ID in the response. When you enable versioning for a bucket, if Amazon S3 receives multiple write requests for the same object simultaneously, it stores all of the objects.
For more information about versioning, see Adding Objects to Versioning Enabled Buckets. For information about returning the versioning state of a bucket, see GetBucketVersioning.

◆ PutObjectAcl()
|
virtual |
Uses the acl subresource to set the access control list (ACL) permissions for a new or existing object in an S3 bucket. You must have WRITE_ACP permission to set the ACL of an object. For more information, see What permissions can I grant? in the Amazon S3 User Guide.
This action is not supported by Amazon S3 on Outposts.
Depending on your application needs, you can choose to set the ACL on an object using either the request body or the headers. For example, if you have an existing application that updates a bucket ACL using the request body, you can continue to use that approach. For more information, see Access Control List (ACL) Overview in the Amazon S3 User Guide.
If your bucket uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. You must use policies to grant access to your bucket and the objects in it. Requests to set ACLs or update ACLs fail and return the AccessControlListNotSupported error code. Requests to read ACLs are still supported. For more information, see Controlling object ownership in the Amazon S3 User Guide.
Access Permissions
You can set access permissions using one of the following methods:
-
Specify a canned ACL with the
x-amz-aclrequest header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. Specify the canned ACL name as the value ofx-amz-acl. If you use this header, you cannot use other access control-specific headers in your request. For more information, see Canned ACL. -
Specify access permissions explicitly with the
x-amz-grant-read,x-amz-grant-read-acp,x-amz-grant-write-acp, andx-amz-grant-full-controlheaders. When using these headers, you specify explicit access permissions and grantees (Amazon Web Services accounts or Amazon S3 groups) who will receive the permission. If you use these ACL-specific headers, you cannot usex-amz-aclheader to set a canned ACL. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview.You specify each grantee as a type=value pair, where the type is one of the following:
-
id– if the value specified is the canonical user ID of an Amazon Web Services account -
uri– if you are granting permissions to a predefined group -
emailAddress– if the value specified is the email address of an Amazon Web Services accountUsing email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:
-
US East (N. Virginia)
-
US West (N. California)
-
US West (Oregon)
-
Asia Pacific (Singapore)
-
Asia Pacific (Sydney)
-
Asia Pacific (Tokyo)
-
Europe (Ireland)
-
South America (São Paulo)
For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.
-
For example, the following
x-amz-grant-readheader grants list objects permission to the two Amazon Web Services accounts identified by their email addresses.x-amz-grant-read: emailAddress="xyz@amazon.com", emailAddress="abc@amazon.com" -
You can use either a canned ACL or specify access permissions explicitly. You cannot do both.
Grantee Values
You can specify the person (grantee) to whom you're assigning access rights (using request elements) in the following ways:
-
By the person's ID:
<Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName> </Grantee>DisplayName is optional and ignored in the request.

This action is not supported by Amazon S3 on Outposts.
This action performs the following types of requests:
-
select- Perform a select query on an archived object -
restore an archive- Restore an archived object
To use this operation, you must have permissions to perform the s3:RestoreObject action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide.
Querying Archives with Select Requests
You use a select type of request to perform SQL queries on archived objects. The archived objects that are being queried by the select request must be formatted as uncompressed comma-separated values (CSV) files. You can run queries and custom analytics on your archived data without having to restore your data to a hotter Amazon S3 tier. For an overview about select requests, see Querying Archived Objects in the Amazon S3 User Guide.
When making a select request, do the following:
-
Define an output location for the select query's output. This must be an Amazon S3 bucket in the same Amazon Web Services Region as the bucket that contains the archive object that is being queried. The Amazon Web Services account that initiates the job must have permissions to write to the S3 bucket. You can specify the storage class and encryption for the output objects stored in the bucket. For more information about output, see Querying Archived Objects in the Amazon S3 User Guide.
For more information about the
S3structure in the request body, see the following:-
Managing Access with ACLs in the Amazon S3 User Guide
-
Protecting Data Using Server-Side Encryption in the Amazon S3 User Guide
-
Define the SQL expression for the
SELECTtype of restoration for your query in the request body'sSelectParametersstructure. You can use expressions like the following examples.-
The following expression returns all records from the specified object.
SELECT * FROM Object -
Assuming that you are not using any headers for data stored in the object, you can specify columns with positional headers.
SELECT s._1, s._2 FROM Object s WHERE s._3 > 100 -
If you have headers and you set the
fileHeaderInfoin theCSVstructure in the request body toUSE, you can specify headers in the query. (If you set thefileHeaderInfofield toIGNORE, the first row is skipped for the query.) You cannot mix ordinal positions with header column names.SELECT s.Id, s.FirstName, s.SSN FROM S3Object s

For more information about using SQL with S3 Glacier Select restore, see SQL Reference for Amazon S3 Select and S3 Glacier Select in the Amazon S3 User Guide.
When making a select request, you can also do the following:
-
To expedite your queries, specify the
Expeditedtier. For more information about tiers, see "Restoring Archives," later in this topic. -
Specify details about the data serialization format of both the input object that is being queried and the serialization of the CSV-encoded query results.
The following are additional important facts about the select feature:
-
The output results are new Amazon S3 objects. Unlike archive retrievals, they are stored until explicitly deleted-manually or through a lifecycle policy.
-
You can issue more than one select request on the same Amazon S3 object. Amazon S3 doesn't deduplicate requests, so avoid issuing duplicate requests.
-
Amazon S3 accepts a select request even if the object has already been restored. A select request doesn’t return error response
409.
Restoring objects
Objects that you archive to the S3 Glacier or S3 Glacier Deep Archive storage class, and S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers are not accessible in real time. For objects in Archive Access or Deep Archive Access tiers you must first initiate a restore request, and then wait until the object is moved into the Frequent Access tier. For objects in S3 Glacier or S3 Glacier Deep Archive storage classes you must first initiate a restore request, and then wait until a temporary copy of the object is available. To access an archived object, you must restore the object for the duration (number of days) that you specify.
To restore a specific object version, you can provide a version ID. If you don't provide a version ID, Amazon S3 restores the current version.
When restoring an archived object (or using a select request), you can specify one of the following data access tier options in the Tier element of the request body:
-
Expedited- Expedited retrievals allow you to quickly access your data stored in the S3 Glacier storage class or S3 Intelligent-Tiering Archive tier when occasional urgent requests for a subset of archives are required. For all but the largest archived objects (250 MB+), data accessed using Expedited retrievals is typically made available within 1–5 minutes. Provisioned capacity ensures that retrieval capacity for Expedited retrievals is available when you need it. Expedited retrievals and provisioned capacity are not available for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier. -
Standard- Standard retrievals allow you to access any of your archived objects within several hours. This is the default option for retrieval requests that do not specify the retrieval option. Standard retrievals typically finish within 3–5 hours for objects stored in the S3 Glacier storage class or S3 Intelligent-Tiering Archive tier. They typically finish within 12 hours for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier. Standard retrievals are free for objects stored in S3 Intelligent-Tiering.
-
Bulk- Bulk retrievals are the lowest-cost retrieval option in S3 Glacier, enabling you to retrieve large amounts, even petabytes, of data inexpensively. Bulk retrievals typically finish within 5–12 hours for objects stored in the S3 Glacier storage class or S3 Intelligent-Tiering Archive tier. They typically finish within 48 hours for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier. Bulk retrievals are free for objects stored in S3 Intelligent-Tiering.
For more information about archive retrieval options and provisioned capacity for Expedited data access, see Restoring Archived Objects in the Amazon S3 User Guide.
You can use Amazon S3 restore speed upgrade to change the restore speed to a faster speed while it is in progress. For more information, see Upgrading the speed of an in-progress restore in the Amazon S3 User Guide.
To get the status of object restoration, you can send a HEAD request. Operations return the x-amz-restore header, which provides information about the restoration status, in the response. You can use Amazon S3 event notifications to notify you when a restore is initiated or completed. For more information, see Configuring Amazon S3 Event Notifications in the Amazon S3 User Guide.
After restoring an archived object, you can update the restoration period by reissuing the request with a new period. Amazon S3 updates the restoration period relative to the current time and charges only for the request-there are no data transfer charges. You cannot update the restoration period when Amazon S3 is actively processing your current restore request for the object.
If your bucket has a lifecycle configuration with a rule that includes an expiration action, the object expiration overrides the life span that you specify in a restore request. For example, if you restore an object copy for 10 days, but the object is scheduled to expire in 3 days, Amazon S3 deletes the object in 3 days. For more information about lifecycle configuration, see PutBucketLifecycleConfiguration and Object Lifecycle Management in Amazon S3 User Guide.
Responses
A successful action returns either the 200 OK or 202 Accepted status code.
-
If the object is not previously restored, then Amazon S3 returns
202 Acceptedin the response. -
If the object is previously restored, Amazon S3 returns
200 OKin the response.

◆ SelectObjectContent()
|
virtual |
This action filters the contents of an Amazon S3 object based on a simple structured query language (SQL) statement. In the request, along with the SQL expression, you must also specify a data serialization format (JSON, CSV, or Apache Parquet) of the object. Amazon S3 uses this format to parse object data into records, and returns only records that match the specified SQL expression. You must also specify the data serialization format for the response.
This action is not supported by Amazon S3 on Outposts.
For more information about Amazon S3 Select, see Selecting Content from Objects and SELECT Command in the Amazon S3 User Guide.
For more information about using SQL with Amazon S3 Select, see SQL Reference for Amazon S3 Select and S3 Glacier Select in the Amazon S3 User Guide.
Permissions
You must have s3:GetObject permission for this operation. Amazon S3 Select does not support anonymous access. For more information about permissions, see Specifying Permissions in a Policy in the Amazon S3 User Guide.
Object Data Formats
You can use Amazon S3 Select to query objects that have the following format properties:
-
CSV, JSON, and Parquet - Objects must be in CSV, JSON, or Parquet format.
-
UTF-8 - UTF-8 is the only encoding type Amazon S3 Select supports.
-
GZIP or BZIP2 - CSV and JSON files can be compressed using GZIP or BZIP2. GZIP and BZIP2 are the only compression formats that Amazon S3 Select supports for CSV and JSON files. Amazon S3 Select supports columnar compression for Parquet using GZIP or Snappy. Amazon S3 Select does not support whole-object compression for Parquet objects.
-
Server-side encryption - Amazon S3 Select supports querying objects that are protected with server-side encryption.
For objects that are encrypted with customer-provided encryption keys (SSE-C), you must use HTTPS, and you must use the headers that are documented in the GetObject. For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) in the Amazon S3 User Guide.
For objects that are encrypted with Amazon S3 managed encryption keys (SSE-S3) and Amazon Web Services KMS keys (SSE-KMS), server-side encryption is handled transparently, so you don't need to specify anything. For more information about server-side encryption, including SSE-S3 and SSE-KMS, see Protecting Data Using Server-Side Encryption in the Amazon S3 User Guide.
Working with the Response Body
Given the response size is unknown, Amazon S3 Select streams the response as a series of messages and includes a Transfer-Encoding header with chunked as its value in the response. For more information, see Appendix: SelectObjectContent Response.
GetObject Support
The SelectObjectContent action does not support the following GetObject functionality. For more information, see GetObject.
-
Range: Although you can specify a scan range for an Amazon S3 Select request (see SelectObjectContentRequestSelectObjectContentRequestScanRange in the request parameters), you cannot specify the range of bytes of an object to return. -
GLACIER, DEEP_ARCHIVE and REDUCED_REDUNDANCY storage classes: You cannot specify the GLACIER, DEEP_ARCHIVE, or
REDUCED_REDUNDANCYstorage classes. For more information, about storage classes see Storage Classes in the Amazon S3 User Guide.

◆ UploadPart()
|
virtual |
Uploads a part in a multipart upload.
In this operation, you provide part data in your request. However, you have an option to specify your existing Amazon S3 object as a data source for the part you are uploading. To upload a part from an existing object, you use the UploadPartCopy operation.
You must initiate a multipart upload (see CreateMultipartUpload) before you can upload any part. In response to your initiate request, Amazon S3 returns an upload ID, a unique identifier, that you must include in your upload part request.
Part numbers can be any number from 1 to 10,000, inclusive. A part number uniquely identifies a part and also defines its position within the object being created. If you upload a new part using the same part number that was used with a previous part, the previously uploaded part is overwritten.
For information about maximum and minimum part sizes and other multipart upload specifications, see Multipart upload limits in the Amazon S3 User Guide.
To ensure that data is not corrupted when traversing the network, specify the Content-MD5 header in the upload part request. Amazon S3 checks the part data against the provided MD5 value. If they do not match, Amazon S3 returns an error.
If the upload request is signed with Signature Version 4, then Amazon Web Services S3 uses the x-amz-content-sha256 header as a checksum instead of Content-MD5. For more information see Authenticating Requests: Using the Authorization Header (Amazon Web Services Signature Version 4).
Note: After you initiate multipart upload and upload one or more parts, you must either complete or abort multipart upload in order to stop getting charged for storage of the uploaded parts. Only after you either complete or abort multipart upload, Amazon S3 frees up the parts storage and stops charging you for the parts storage.
For more information on multipart uploads, go to Multipart Upload Overview in the Amazon S3 User Guide .
For information on the permissions required to use the multipart upload API, go to Multipart Upload and Permissions in the Amazon S3 User Guide.
You can optionally request server-side encryption where Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it for you when you access it. You have the option of providing your own encryption key, or you can use the Amazon Web Services managed encryption keys. If you choose to provide your own encryption key, the request headers you provide in the request must match the headers you used in the request to initiate the upload by using CreateMultipartUpload. For more information, go to Using Server-Side Encryption in the Amazon S3 User Guide.
Server-side encryption is supported by the S3 Multipart Upload actions. Unless you are using a customer-provided encryption key, you don't need to specify the encryption parameters in each UploadPart request. Instead, you only need to specify the server-side encryption parameters in the initial Initiate Multipart request. For more information, see CreateMultipartUpload.
If you requested server-side encryption using a customer-provided encryption key in your initiate multipart upload request, you must provide identical encryption information in each part upload using the following headers.
-
x-amz-server-side-encryption-customer-algorithm
-
x-amz-server-side-encryption-customer-key
-
x-amz-server-side-encryption-customer-key-MD5
Special Errors
-
-
Code: NoSuchUpload
-
Cause: The specified multipart upload does not exist. The upload ID might be invalid, or the multipart upload might have been aborted or completed.
-
HTTP Status Code: 404 Not Found

Uploads a part by copying data from an existing object as data source. You specify the data source by adding the request header x-amz-copy-source in your request and a byte range by adding the request header x-amz-copy-source-range in your request.
For information about maximum and minimum part sizes and other multipart upload specifications, see Multipart upload limits in the Amazon S3 User Guide.
Instead of using an existing object as part data, you might use the UploadPart action and provide data in your request.
You must initiate a multipart upload before you can upload any part. In response to your initiate request. Amazon S3 returns a unique identifier, the upload ID, that you must include in your upload part request.

Note the following additional considerations about the request headers x-amz-copy-source-if-match, x-amz-copy-source-if-none-match, x-amz-copy-source-if-unmodified-since, and x-amz-copy-source-if-modified-since:
-
Consideration 1 - If both of the
x-amz-copy-source-if-matchandx-amz-copy-source-if-unmodified-sinceheaders are present in the request as follows:x-amz-copy-source-if-matchcondition evaluates totrue, and;x-amz-copy-source-if-unmodified-sincecondition evaluates tofalse;Amazon S3 returns
200 OKand copies the data. -
Consideration 2 - If both of the
x-amz-copy-source-if-none-matchandx-amz-copy-source-if-modified-sinceheaders are present in the request as follows:x-amz-copy-source-if-none-matchcondition evaluates tofalse, and;x-amz-copy-source-if-modified-sincecondition evaluates totrue;Amazon S3 returns
412 Precondition Failedresponse code.
Versioning
If your bucket has versioning enabled, you could have multiple versions of the same object. By default, x-amz-copy-source identifies the current version of the object to copy. If the current version is a delete marker and you don't specify a versionId in the x-amz-copy-source, Amazon S3 returns a 404 error, because the object does not exist. If you specify versionId in the x-amz-copy-source and the versionId is a delete marker, Amazon S3 returns an HTTP 400 error, because you are not allowed to specify a delete marker as a version for the x-amz-copy-source.
You can optionally specify a specific version of the source object to copy by adding the versionId subresource as shown in the following example:
x-amz-copy-source: /bucket/object?versionId=version id

Passes transformed objects to a GetObject operation when using Object Lambda access points. For information about Object Lambda access points, see Transforming objects with Object Lambda access points in the Amazon S3 User Guide.
This operation supports metadata that can be returned by GetObject, in addition to RequestRoute, RequestToken, StatusCode, ErrorCode, and ErrorMessage. The GetObject response metadata is supported so that the WriteGetObjectResponse caller, typically an Lambda function, can provide the same metadata when it internally invokes GetObject. When WriteGetObjectResponse is called by a customer-owned Lambda function, the metadata returned to the end user GetObject call might differ from what Amazon S3 would normally return.
You can include any number of metadata headers. When including a metadata header, it should be prefaced with x-amz-meta. For example, x-amz-meta-my-custom-header: MyCustomValue. The primary use case for this is to forward GetObject metadata.
Amazon Web Services provides some prebuilt Lambda functions that you can use with S3 Object Lambda to detect and redact personally identifiable information (PII) and decompress S3 objects. These Lambda functions are available in the Amazon Web Services Serverless Application Repository, and can be selected through the Amazon Web Services Management Console when you create your Object Lambda access point.
Example 1: PII Access Control - This Lambda function uses Amazon Comprehend, a natural language processing (NLP) service using machine learning to find insights and relationships in text. It automatically detects personally identifiable information (PII) such as names, addresses, dates, credit card numbers, and social security numbers from documents in your Amazon S3 bucket.
Example 2: PII Redaction - This Lambda function uses Amazon Comprehend, a natural language processing (NLP) service using machine learning to find insights and relationships in text. It automatically redacts personally identifiable information (PII) such as names, addresses, dates, credit card numbers, and social security numbers from documents in your Amazon S3 bucket.
Example 3: Decompression - The Lambda function S3ObjectLambdaDecompression, is equipped to decompress objects stored in S3 in one of six compressed file formats including bzip2, gzip, snappy, zlib, zstandard and ZIP.
For information on how to view and use these functions, see Using Amazon Web Services built Lambda functions in the Amazon S3 User Guide.
