org.apache.flink.table.runtime.operators.dynamicfiltering.DynamicFilteringDataCollectorOperatorCoordinator

All Implemented Interfaces:

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

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

The operator coordinator for DynamicFilteringDataCollectorOperator. The coordinator collects DynamicFilteringEvent then redistributes to listening source coordinators.
