[jira] [Created] (FLINK-8753) Introduce Incremental savepoint

Sihua Zhou created FLINK-8753:
---------------------------------

             Summary: 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


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.
