-----------------------------------------
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.
