Class BatchCoBroadcastWithNonKeyedOperator<IN1,IN2,OUT>

java.lang.Object

org.apache.flink.streaming.api.operators.AbstractStreamOperator<OUT>

org.apache.flink.streaming.api.operators.AbstractUdfStreamOperator<OUT,BroadcastProcessFunction<IN1,IN2,OUT>>

org.apache.flink.streaming.api.operators.co.CoBroadcastWithNonKeyedOperator<IN1,IN2,OUT>

org.apache.flink.streaming.api.operators.co.BatchCoBroadcastWithNonKeyedOperator<IN1,IN2,OUT>

Type Parameters:

IN1 - The input type of the regular (non-broadcast) side.

IN2 - The input type of the broadcast side.

OUT - The output type of the operator.

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.state.CheckpointListener, BoundedMultiInput, InputSelectable, KeyContext, KeyContextHandler, org.apache.flink.streaming.api.operators.OutputTypeConfigurable<OUT>, SetupableStreamOperator<OUT>, StreamOperator<OUT>, StreamOperatorStateHandler.CheckpointedStreamOperator, TwoInputStreamOperator<IN1,IN2,OUT>, UserFunctionProvider<BroadcastProcessFunction<IN1,IN2,OUT>>

@Internal
public class BatchCoBroadcastWithNonKeyedOperator<IN1,IN2,OUT>
extends CoBroadcastWithNonKeyedOperator<IN1,IN2,OUT>
implements BoundedMultiInput, InputSelectable

A TwoInputStreamOperator for executing BroadcastProcessFunctions in RuntimeExecutionMode.BATCH execution mode.

Compared to CoBroadcastWithNonKeyedOperator this uses BoundedMultiInput and InputSelectable to enforce the requirement that the broadcast side is processed before the regular input.

Method Detail

endInput

public void endInput(int inputId)
              throws Exception

Description copied from interface: BoundedMultiInput

It is notified that no more data will arrive from the input identified by the inputId. The inputId is numbered starting from 1, and `1` indicates the first input.

WARNING: It is not safe to use this method to commit any transactions or other side effects! You can use this method to e.g. flush data buffered for the given input or implement an ordered reading from multiple inputs via InputSelectable.

Specified by:

endInput in interface BoundedMultiInput

Throws:

Exception

nextSelection

public InputSelection nextSelection()

Description copied from interface: InputSelectable

Returns the next InputSelection that wants to get the record. This method is guaranteed to not be called concurrently with other methods of the operator.

Specified by:

nextSelection in interface InputSelectable

processElement1

public void processElement1(StreamRecord<IN1> element)
                     throws Exception

Description copied from interface: TwoInputStreamOperator

Processes one element that arrived on the first input of this two-input operator. This method is guaranteed to not be called concurrently with other methods of the operator.

Specified by:

processElement1 in interface TwoInputStreamOperator<IN1,IN2,OUT>

Overrides:

processElement1 in class CoBroadcastWithNonKeyedOperator<IN1,IN2,OUT>

Throws:

Exception
