--------------------------------
Assignee: vinoyang
> Cancel checkpoint operations belonging to a discarded/aborted checkpoint
> ------------------------------------------------------------------------
>
> Key: FLINK-12058
> URL: https://issues.apache.org/jira/browse/FLINK-12058
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Checkpointing
> Affects Versions: 1.7.2, 1.8.0
> Reporter: Till Rohrmann
> Assignee: vinoyang
> Priority: Major
>
> In order to save CPU cycles and reduce disk and network I/O, we should try to
> cancel local checkpoint operations belonging to discarded aborted or subsumed
> checkpoints. For example, if a {{Task}} declines a checkpoint, the
> {{CheckpointCoordinator}} will discard this checkpoint. However, other
> checkpointing operations belonging to this checkpoint won't be necessarily
> notified and canceled.
> The notification mechanism could piggy back on the existing
> {{CancelCheckpointMarker}} or be a separate signal sent to all participating
> {{Tasks}}.
