Method Detail

forStage

public static FlinkStreamingSideInputHandlerFactory forStage(org.apache.beam.runners.core.construction.graph.ExecutableStage stage,
                                                             java.util.Map<org.apache.beam.model.pipeline.v1.RunnerApi.ExecutableStagePayload.SideInputId,org.apache.beam.sdk.values.PCollectionView<?>> viewMapping,
                                                             org.apache.beam.runners.core.SideInputHandler runnerHandler)

Creates a new state handler for the given stage. Note that this requires a traversal of the stage itself, so this should only be called once per stage rather than once per bundle.

forSideInput
