> Introduce Incremental savepoint
> -------------------------------
>                 Key: FLINK-8753
>                 URL: https://issues.apache.org/jira/browse/FLINK-8753
>             Project: Flink
>          Issue Type: New Feature
>          Components: State Backends, Checkpointing
>    Affects Versions: 1.5.0
>            Reporter: Sihua Zhou
>            Assignee: Sihua Zhou
>            Priority: Major
> Right now, savepoint goes through the full checkpoint path, take a savepoint 
> could be slowly. In our production, for some long term job it often costs 
> more than 10min to complete a savepoint which is unacceptable for a real time 
> job, so we have to turn back to use the externalized checkpoint instead 
> currently. But the externalized  checkpoint has a time interval (checkpoint 
> interval) between the last time. So I proposal to introduce the increment 
> savepoint which goes through the increment checkpoint path.
> Any advice would be appreciated!
