[jira] [Created] (FLINK-17741) Create integration or e2e test for out of order (savepoint) barriers

Roman Khachatryan created FLINK-17741:
-----------------------------------------

             Summary: Create integration or e2e test for out of order (savepoint) barriers
                 Key: FLINK-17741
                 URL: https://issues.apache.org/jira/browse/FLINK-17741
             Project: Flink
          Issue Type: Test
          Components: Tests
            Reporter: Roman Khachatryan


Unaligned checkpoints MVP assumes at most one barrier at a time. This is ensured by max-concurrent-checkpoints on CheckpointCoordinator.

But it seems possible that CheckpointCoordinator considers a checkpoint canceled, starts a new one, while some old barriers are still flowing in the graph.

As of now, this situation isn't tested.
