EndOfData (Flink : Runtime 2.0-preview1 API)

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.
