All Implemented Interfaces:
Serializable, SdkPojo, ToCopyableBuilder<S3JsonSource.Builder,S3JsonSource>
@Generated("software.amazon.awssdk:codegen") public final class S3JsonSource extends Object implements SdkPojo, Serializable, ToCopyableBuilder<S3JsonSource.Builder,S3JsonSource>

Specifies a JSON data store stored in Amazon S3.

  • Method Details

    • name

      public final String name()

      The name of the data store.

      Returns:
      The name of the data store.

    • hasPaths

      public final boolean hasPaths()
      For responses, this returns true if the service returned a value for the Paths property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • paths

      public final List<String> paths()

      A list of the Amazon S3 paths to read from.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasPaths() method.

      Returns:
      A list of the Amazon S3 paths to read from.

    • compressionType

      public final CompressionType compressionType()

      Specifies how the data is compressed. This is generally not necessary if the data has a standard file extension. Possible values are "gzip" and "bzip").

      If the service returns an enum value that is not available in the current SDK version, compressionType will return CompressionType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from compressionTypeAsString().

      Returns:
      Specifies how the data is compressed. This is generally not necessary if the data has a standard file extension. Possible values are "gzip" and "bzip").
      See Also:

    • compressionTypeAsString

      public final String compressionTypeAsString()

      Specifies how the data is compressed. This is generally not necessary if the data has a standard file extension. Possible values are "gzip" and "bzip").

      If the service returns an enum value that is not available in the current SDK version, compressionType will return CompressionType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from compressionTypeAsString().

      Returns:
      Specifies how the data is compressed. This is generally not necessary if the data has a standard file extension. Possible values are "gzip" and "bzip").

    • hasExclusions

      public final boolean hasExclusions()
      For responses, this returns true if the service returned a value for the Exclusions property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • exclusions

      public final List<String> exclusions()

      A string containing a JSON list of Unix-style glob patterns to exclude. For example, "[\"**.pdf\"]" excludes all PDF files.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasExclusions() method.

      Returns:
      A string containing a JSON list of Unix-style glob patterns to exclude. For example, "[\"**.pdf\"]" excludes all PDF files.

    • groupSize

      public final String groupSize()

      The target group size in bytes. The default is computed based on the input data size and the size of your cluster. When there are fewer than 50,000 input files, "groupFiles" must be set to "inPartition" for this to take effect.

      Returns:
      The target group size in bytes. The default is computed based on the input data size and the size of your cluster. When there are fewer than 50,000 input files, "groupFiles" must be set to "inPartition" for this to take effect.

    • groupFiles

      public final String groupFiles()

      Grouping files is turned on by default when the input contains more than 50,000 files. To turn on grouping with fewer than 50,000 files, set this parameter to "inPartition". To disable grouping when there are more than 50,000 files, set this parameter to "none".

      Returns:
      Grouping files is turned on by default when the input contains more than 50,000 files. To turn on grouping with fewer than 50,000 files, set this parameter to "inPartition". To disable grouping when there are more than 50,000 files, set this parameter to "none".

    • recurse

      public final Boolean recurse()

      If set to true, recursively reads files in all subdirectories under the specified paths.

      Returns:
      If set to true, recursively reads files in all subdirectories under the specified paths.

    • maxBand

      public final Integer maxBand()

      This option controls the duration in milliseconds after which the s3 listing is likely to be consistent. Files with modification timestamps falling within the last maxBand milliseconds are tracked specially when using JobBookmarks to account for Amazon S3 eventual consistency. Most users don't need to set this option. The default is 900000 milliseconds, or 15 minutes.

      Returns:
      This option controls the duration in milliseconds after which the s3 listing is likely to be consistent. Files with modification timestamps falling within the last maxBand milliseconds are tracked specially when using JobBookmarks to account for Amazon S3 eventual consistency. Most users don't need to set this option. The default is 900000 milliseconds, or 15 minutes.

    • maxFilesInBand

      public final Integer maxFilesInBand()

      This option specifies the maximum number of files to save from the last maxBand seconds. If this number is exceeded, extra files are skipped and only processed in the next job run.

      Returns:
      This option specifies the maximum number of files to save from the last maxBand seconds. If this number is exceeded, extra files are skipped and only processed in the next job run.

    • additionalOptions

      public final S3DirectSourceAdditionalOptions additionalOptions()

      Specifies additional connection options.

      Returns:
      Specifies additional connection options.

    • jsonPath

      public final String jsonPath()

      A JsonPath string defining the JSON data.

      Returns:
      A JsonPath string defining the JSON data.

    • multiline

      public final Boolean multiline()

      A Boolean value that specifies whether a single record can span multiple lines. This can occur when a field contains a quoted new-line character. You must set this option to True if any record spans multiple lines. The default value is False, which allows for more aggressive file-splitting during parsing.

      Returns:
      A Boolean value that specifies whether a single record can span multiple lines. This can occur when a field contains a quoted new-line character. You must set this option to True if any record spans multiple lines. The default value is False, which allows for more aggressive file-splitting during parsing.

    • hasOutputSchemas

      public final boolean hasOutputSchemas()
      For responses, this returns true if the service returned a value for the OutputSchemas property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • outputSchemas

      public final List<GlueSchema> outputSchemas()
