Package com.google.cloud.dataflow.sdk.transforms Description

Defines PTransforms for transforming data in a pipeline.

A PTransform is an operation that takes an InputT (some subtype of PInput) and produces an OutputT (some subtype of POutput).

Common PTransforms include root PTransforms like TextIO.Read and Create, processing and conversion operations like ParDo, GroupByKey, CoGroupByKey, Combine, and Count, and outputting PTransforms like TextIO.Write.

New PTransforms can be created by composing existing PTransforms. Most PTransforms in this package are composites, and users can also create composite PTransforms for their own application-specific logic.
