[jira] [Created] (FLINK-25191) Skip savepoints for recovery

Dawid Wysakowicz created FLINK-25191:
----------------------------------------

             Summary: Skip savepoints for recovery
                 Key: FLINK-25191
                 URL: https://issues.apache.org/jira/browse/FLINK-25191
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Checkpointing
            Reporter: Dawid Wysakowicz
             Fix For: 1.15.0


Intermediate savepoints should not be used for recovery. In order to achieve that we should:
* do not send {{notifyCheckpointComplete}} for intermediate savepoints
* do not add them to {{CompletedCheckpointStore}}

Important! Synchronous savepoints (stop-with-savepoint) should still commit side-effects. We need to distinguish them from the intermediate savepoints.
