      • sideOutputLeftLateData

        @PublicEvolving
public KeyedStream.IntervalJoined<IN1,​IN2,​KEY> sideOutputLeftLateData​(org.apache.flink.util.OutputTag<IN1> outputTag)
        Send late arriving left-side data to the side output identified by the given OutputTag. Data is considered late after the watermark

      • sideOutputRightLateData

        @PublicEvolving
public KeyedStream.IntervalJoined<IN1,​IN2,​KEY> sideOutputRightLateData​(org.apache.flink.util.OutputTag<IN2> outputTag)
        Send late arriving right-side data to the side output identified by the given OutputTag. Data is considered late after the watermark

      • process

        @PublicEvolving
public <OUT> SingleOutputStreamOperator<OUT> process​(ProcessJoinFunction<IN1,​IN2,​OUT> processJoinFunction)
        Completes the join operation with the given user function that is executed for each joined pair of elements.
        Type Parameters:
        OUT - The output type.
        Parameters:
        processJoinFunction - The user-defined process join function.
        Returns:
        The transformed DataStream.

public <OUT> SingleOutputStreamOperator<OUT> process​(ProcessJoinFunction<IN1,​IN2,​OUT> processJoinFunction,
                                                     org.apache.flink.api.common.typeinfo.TypeInformation<OUT> outputType)
        Completes the join operation with the given user function that is executed for each joined pair of elements. This methods allows for passing explicit type information for the output type.
        Type Parameters:
        OUT - The output type.
        Parameters:
        processJoinFunction - The user-defined process join function.
        outputType - The type information for the output type.
        Returns:
        The transformed DataStream.

      • enableAsyncState

        @Experimental
public KeyedStream.IntervalJoined<IN1,​IN2,​KEY> enableAsyncState()
        Enable the async state processing for following keyed processing function. This also requires only State V2 APIs are used in the function.
        Returns:
        the configured IntervalJoin itself.
