-----------------------------------
Hi [~srichter][~yanghua]I think this is a bit looks like a duplicate of this
[FLINK-8871|https://issues.apache.org/jira/browse/FLINK-8871] which needs a
good discussion as you([~srichter]) have mentioned, or
[FLINK-8871|https://issues.apache.org/jira/browse/FLINK-8871] should be blocked
by this ticket (which only finish the RPC related works)? Maybe we should
connect these two guys together to get a better picture...what do you think?
> Introduce AbortCheckpoint message from JM to TMs
> ------------------------------------------------
>
> Key: FLINK-9375
> URL: https://issues.apache.org/jira/browse/FLINK-9375
> Project: Flink
> Issue Type: Improvement
> Components: State Backends, Checkpointing
> Reporter: Stefan Richter
> Assignee: vinoyang
> Priority: Major
>
> We should introduce an {{AbortCheckpoint}} message that a jobmanager can send
> to taskmanagers if a checkpoint is canceled so that the operators can eagerly
> stop their alignment phase and continue to normal processing. This can reduce
> some backpressure issues in the context of canceled and restarted checkpoints.
