类 CollectSinkOperatorCoordinator

java.lang.Object

org.apache.flink.streaming.api.operators.collect.CollectSinkOperatorCoordinator

所有已实现的接口:

AutoCloseable, org.apache.flink.runtime.operators.coordination.CoordinationRequestHandler, org.apache.flink.runtime.operators.coordination.OperatorCoordinator, org.apache.flink.runtime.state.CheckpointListener

public class CollectSinkOperatorCoordinator
extends Object
implements org.apache.flink.runtime.operators.coordination.OperatorCoordinator, org.apache.flink.runtime.operators.coordination.CoordinationRequestHandler

OperatorCoordinator for CollectSinkFunction.

This coordinator only forwards requests and responses from clients and sinks and it does not store any results in itself.
