Steven Zhen Wu commented on FLINK-12619:
----------------------------------------
It is very useful to support optimized/incremental/light-weight snapshot
(checkpoint or savepoint) during stop. E.g. it can help with redeployment case
to minimize/avoid duplicates for non-exactly-once sink, where parallelism and
state backend remained the same.
> Support TERMINATE/SUSPEND Job with Checkpoint

> Inspired by the idea of FLINK-11458, we propose to support terminate/suspend
> a job with checkpoint. This improvement cooperates with incremental and
> external checkpoint features, that if checkpoint is retained and this feature
> is configured, we will trigger a checkpoint before the job stops. It could
> accelarate job recovery a lot since:
> 1. No source rewinding required any more.
> 2. It's much faster than taking a savepoint since incremental checkpoint is
> enabled.
> Please note that conceptually savepoints is different from checkpoint in a
> similar way that backups are different from recovery logs in traditional
> database systems. So we suggest using this feature only for job recovery,
> while stick with FLINK-11458 for the
> upgrading/cross-cluster-job-migration/state-backend-switch cases.
