[jira] [Created] (FLINK-16177) Integrate Operator Coordinators with Checkpoints

Stephan Ewen created FLINK-16177:
------------------------------------

             Summary: Integrate Operator Coordinators with Checkpoints
                 Key: FLINK-16177
                 URL: https://issues.apache.org/jira/browse/FLINK-16177
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Checkpointing
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 1.11.0


The operator coordinators are stateful and hence need to store state in checkpoints.

See FLIP-27 for details on operator coordinators: https://cwiki.apache.org/confluence/display/FLINK/FLIP-27%3A+Refactor+Source+Interface

The initial implementation approach is to trigger coordinator checkpoints first, and when all coordinator checkpoints are done, then the source checkpoint barriers will be injected.

_Note:_ This functionality will eventually replace the checkpoint master hooks.
