All Implemented Interfaces:

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

public class ClusteringOperator
extends org.apache.flink.table.runtime.operators.TableStreamOperator<ClusteringCommitEvent>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<ClusteringPlanEvent,ClusteringCommitEvent>, org.apache.flink.streaming.api.operators.BoundedOneInput

Operator to execute the actual clustering task assigned by the clustering plan task. In order to execute scalable, the input should shuffle by the clustering event ClusteringPlanEvent.
