CancelCheckpointMarker (Flink : 2.0-SNAPSHOT API)

java.lang.Object
- org.apache.flink.runtime.event.AbstractEvent
- - org.apache.flink.runtime.event.RuntimeEvent
  - - org.apache.flink.runtime.io.network.api.CancelCheckpointMarker

All Implemented Interfaces:

IOReadableWritable
```
public class CancelCheckpointMarker
extends RuntimeEvent
```
The CancelCheckpointMarker travels through the data streams, similar to the CheckpointBarrier, but signals that a certain checkpoint should be canceled. Any in-progress alignment for that checkpoint needs to be canceled and regular processing should be resumed.
