Class ClusteringPlanOperator

java.lang.Object

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

org.apache.hudi.sink.clustering.ClusteringPlanOperator

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.state.CheckpointListener, org.apache.flink.streaming.api.operators.Input<Object>, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.OneInputStreamOperator<Object,ClusteringPlanEvent>, org.apache.flink.streaming.api.operators.SetupableStreamOperator<ClusteringPlanEvent>, org.apache.flink.streaming.api.operators.StreamOperator<ClusteringPlanEvent>, org.apache.flink.streaming.api.operators.StreamOperatorStateHandler.CheckpointedStreamOperator

public class ClusteringPlanOperator
extends org.apache.flink.streaming.api.operators.AbstractStreamOperator<ClusteringPlanEvent>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<Object,ClusteringPlanEvent>

Operator that generates the clustering plan with pluggable strategies on finished checkpoints.

It should be singleton to avoid conflicts.
