Class KeyedMapBundleOperator<K,V,IN,OUT>

java.lang.Object

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

org.apache.flink.table.runtime.operators.bundle.AbstractMapBundleOperator<K,V,IN,OUT>

org.apache.flink.table.runtime.operators.bundle.KeyedMapBundleOperator<K,V,IN,OUT>

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.state.CheckpointListener, org.apache.flink.streaming.api.operators.Input<IN>, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.KeyContextHandler, org.apache.flink.streaming.api.operators.OneInputStreamOperator<IN,OUT>, org.apache.flink.streaming.api.operators.SetupableStreamOperator<OUT>, org.apache.flink.streaming.api.operators.StreamOperator<OUT>, org.apache.flink.streaming.api.operators.StreamOperatorStateHandler.CheckpointedStreamOperator, BundleTriggerCallback

public class KeyedMapBundleOperator<K,V,IN,OUT>
extends AbstractMapBundleOperator<K,V,IN,OUT>

The KeyedMapBundleOperator uses framework's key as bundle map key, thus can only be used on org.apache.flink.streaming.api.datastream.KeyedStream.
