Overview

Note:

When passing TransformInput as input to an Aws::Client method, you can use a vanilla Hash:

{
  data_source: { # required
    s3_data_source: { # required
      s3_data_type: "ManifestFile", # required, accepts ManifestFile, S3Prefix, AugmentedManifestFile
      s3_uri: "S3Uri", # required
    },
  },
  content_type: "ContentType",
  compression_type: "None", # accepts None, Gzip
  split_type: "None", # accepts None, Line, RecordIO, TFRecord
}

Describes the input source of a transform job and the way the transform job consumes it.

Instance Attribute Details

#compression_typeString

If your transform data is compressed, specify the compression type. Amazon SageMaker automatically decompresses the data for the transform job accordingly. The default value is None.

Possible values:

  • None
  • Gzip

Returns:

  • (String)

    If your transform data is compressed, specify the compression type.

#content_typeString

The multipurpose internet mail extension (MIME) type of the data. Amazon SageMaker uses the MIME type with each http call to transfer data to the transform job.

Returns:

  • (String)

    The multipurpose internet mail extension (MIME) type of the data.

#data_sourceTypes::TransformDataSource

Describes the location of the channel data, which is, the S3 location of the input data that the model can consume.

Returns:

  • (Types::TransformDataSource)

    Describes the location of the channel data, which is, the S3 location of the input data that the model can consume.

#split_typeString

The method to use to split the transform job\'s data files into smaller batches. Splitting is necessary when the total size of each object is too large to fit in a single request. You can also use data splitting to improve performance by processing multiple concurrent mini-batches. The default value for SplitType is None, which indicates that input data files are not split, and request payloads contain the entire contents of an input object. Set the value of this parameter to Line to split records on a newline character boundary. SplitType also supports a number of record-oriented binary data formats.

When splitting is enabled, the size of a mini-batch depends on the values of the BatchStrategy and MaxPayloadInMB parameters. When the value of BatchStrategy is MultiRecord, Amazon SageMaker sends the maximum number of records in each request, up to the MaxPayloadInMB limit. If the value of BatchStrategy is SingleRecord, Amazon SageMaker sends individual records in each request.

Some data formats represent a record as a binary payload wrapped with extra padding bytes. When splitting is applied to a binary data format, padding is removed if the value of BatchStrategy is set to SingleRecord. Padding is not removed if the value of BatchStrategy is set to MultiRecord.

For more information about the RecordIO, see Data Format in the MXNet documentation. For more information about the TFRecord, see Consuming TFRecord data in the TensorFlow documentation.

Returns:

  • (String)

    The method to use to split the transform job\'s data files into smaller batches.
