s3Uri
Depending on the value specified for the S3DataType
, identifies either a key name prefix or a manifest. For example:
A key name prefix might look like this:
s3://bucketname/exampleprefix/
.A manifest might look like this:
s3://bucketname/example.manifest
The manifest is an S3 object which is a JSON file with the following format:[ {"prefix": "s3://customer_bucket/some/prefix/"},``"relative/path/to/custdata-1",``"relative/path/custdata-2",``...``"relative/path/custdata-N"``]
The preceding JSON matches the followingS3Uris
:s3://customer_bucket/some/prefix/relative/path/to/custdata-1``s3://customer_bucket/some/prefix/relative/path/custdata-2``...``s3://customer_bucket/some/prefix/relative/path/custdata-N
The complete set ofS3Uris
in this manifest constitutes the input data for the channel for this datasource. The object that eachS3Uris
points to must be readable by the IAM role that Amazon SageMaker uses to perform tasks on your behalf.
