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.StreamOperator<OUT>, org.apache.flink.streaming.api.operators.StreamOperatorStateHandler.CheckpointedStreamOperator, org.apache.flink.streaming.api.operators.YieldingOperator<OUT>, 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 KeyedStream.
