org.apache.flink.streaming.api.operators.python.process.ExternalPythonBatchCoBroadcastProcessOperator<IN1,IN2,OUT>

Type Parameters:

IN1 - The input type of the regular stream

IN2 - The input type of the broadcast stream

OUT - The output type of the CoBroadcastProcess function

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.state.CheckpointListener, org.apache.flink.api.java.typeutils.ResultTypeQueryable<OUT>, org.apache.flink.streaming.api.operators.BoundedMultiInput, org.apache.flink.streaming.api.operators.InputSelectable, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.KeyContextHandler, DataStreamPythonFunctionOperator<OUT>, org.apache.flink.streaming.api.operators.StreamOperator<OUT>, org.apache.flink.streaming.api.operators.StreamOperatorStateHandler.CheckpointedStreamOperator, org.apache.flink.streaming.api.operators.TwoInputStreamOperator<IN1,IN2,OUT>, org.apache.flink.streaming.api.operators.YieldingOperator<OUT>

@Internal
public class ExternalPythonBatchCoBroadcastProcessOperator<IN1,IN2,OUT>
extends ExternalPythonCoProcessOperator<IN1,IN2,OUT>
implements org.apache.flink.streaming.api.operators.BoundedMultiInput, org.apache.flink.streaming.api.operators.InputSelectable

The ExternalPythonBatchCoBroadcastProcessOperator is responsible for executing the Python CoBroadcastProcess Function under BATCH mode, ExternalPythonCoProcessOperator is used under STREAMING mode. This operator forces to run out data from broadcast side first, and then process data from regular side.
