Class EndOfData

java.lang.Object

org.apache.flink.runtime.event.AbstractEvent

org.apache.flink.runtime.event.RuntimeEvent

org.apache.flink.runtime.io.network.api.EndOfData

All Implemented Interfaces:

org.apache.flink.core.io.IOReadableWritable

public class EndOfData
extends RuntimeEvent

This event indicates there will be no more data records in a subpartition. There still might be other events, in particular CheckpointBarriers traveling. The EndOfData is acknowledged by the downstream task. That way we can safely assume the downstream task has consumed all the produced records and therefore we can perform a final checkpoint for the upstream task.
