expand

public WriteResult expand(PCollection<KV<DestinationT,ElementT>> 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:

expandInconsistent

expandTriggered

expandUntriggered

public WriteResult expandUntriggered(PCollection<KV<DestinationT,ElementT>> input,
