BaseKeyedTwoOutputProcessOperator

public class TwoOutputProcessOperator<IN,OUT_MAIN,OUT_SIDE>
extends org.apache.flink.runtime.asyncprocessing.operators.AbstractAsyncStateUdfStreamOperator<OUT_MAIN,org.apache.flink.datastream.api.function.TwoOutputStreamProcessFunction<IN,OUT_MAIN,OUT_SIDE>>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<IN,OUT_MAIN>, org.apache.flink.streaming.api.operators.BoundedOneInput

Operator for TwoOutputStreamProcessFunction.

We support the second output via flink side-output mechanism.
