Class MiniBatchAssignerOperator

java.lang.Object

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

org.apache.flink.table.runtime.operators.wmassigners.MiniBatchAssignerOperator

All Implemented Interfaces:

Serializable, org.apache.flink.runtime.state.CheckpointListener, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.OneInputStreamOperator<BaseRow,BaseRow>, org.apache.flink.streaming.api.operators.SetupableStreamOperator<BaseRow>, org.apache.flink.streaming.api.operators.StreamOperator<BaseRow>, org.apache.flink.streaming.runtime.tasks.ProcessingTimeCallback, org.apache.flink.util.Disposable

public class MiniBatchAssignerOperator
extends org.apache.flink.streaming.api.operators.AbstractStreamOperator<BaseRow>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<BaseRow,BaseRow>, org.apache.flink.streaming.runtime.tasks.ProcessingTimeCallback

A stream operator that emits mini-batch marker in a given period. NOTE: the mini-batch marker uses watermark instead
