Method Detail

forStage

public static BatchSideInputHandlerFactory forStage(org.apache.beam.runners.core.construction.graph.ExecutableStage stage,
                                                    BatchSideInputHandlerFactory.SideInputGetter sideInputGetter)

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.

forIterableSideInput

public <V,W extends org.apache.beam.sdk.transforms.windowing.BoundedWindow> StateRequestHandlers.IterableSideInputHandler<V,W> forIterableSideInput(java.lang.String transformId,
                                                                                                                                                                java.lang.String sideInputId,

                                                                                                                                                                org.apache.beam.sdk.coders.Coder<W> windowCoder)

Description copied from interface: StateRequestHandlers.SideInputHandlerFactory

Returns an StateRequestHandlers.IterableSideInputHandler for the given pTransformId,


 sideInputId

. The supplied elementCoder and windowCoder should be used to encode/decode their respective values.

Specified by:: forIterableSideInput in interface StateRequestHandlers.SideInputHandlerFactory
