> 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.
