      public RedisIO.ReadBytes withOutputParallelization(boolean outputParallelization)
      Whether to reshuffle the resulting PCollection so results are distributed to all workers. The default is to parallelize and should only be changed if this is known to be unnecessary.

    • populateDisplayData

      public void populateDisplayData(DisplayData.Builder builder)
      Description copied from class: PTransform
      Register display data for the given transform or component.

      populateDisplayData(DisplayData.Builder) is invoked by Pipeline runners to collect display data via DisplayData.from(HasDisplayData). Implementations may call super.populateDisplayData(builder) in order to register display data in the current namespace, but should otherwise use subcomponent.populateDisplayData(builder) to use the namespace of the subcomponent.

      By default, does not register any display data. Implementors may override this method to provide their own display data.

      Specified by:
      populateDisplayData in interface HasDisplayData
      Overrides:
      populateDisplayData in class PTransform<PBegin,PCollection<KV<byte[],byte[]>>>
      Parameters:
      builder - The builder to populate with display data.

    • expand

      public PCollection<KV<byte[],byte[]>> expand(PBegin input)
      Description copied from class: PTransform
      Override this method to specify how this PTransform should be expanded on the given InputT.

      NOTE: This method should not be called directly. Instead apply the PTransform should be applied to the InputT using the apply method.

      Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).

      Specified by:
      expand in class PTransform<PBegin,PCollection<KV<byte[],byte[]>>>
