Expand description
Describes the input source of a transform job and the way the transform job consumes it.
Fields (Non-exhaustive)
This struct is marked as non-exhaustive
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.data_source: Option<TransformDataSource>
Describes the location of the channel data, which is, the S3 location of the input data that the model can consume.
content_type: Option<String>
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.
compression_type: Option<CompressionType>
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
.
split_type: Option<SplitType>
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. Currently, the supported record formats are:
-
RecordIO
-
TFRecord
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 RecordIO
, see Create a Dataset Using
RecordIO in the MXNet documentation. For more information about
TFRecord
, see Consuming TFRecord data in the TensorFlow documentation.
