[jira] [Created] (FLINK-6328) Savepoints must not be counted as
retained checkpoints
Stephan Ewen created FLINK-6328:
-----------------------------------
Summary: Savepoints must not be counted as retained checkpoints
Key: FLINK-6328
URL: https://issues.apache.org/jira/browse/FLINK-6328
Project: Flink
Issue Type: Bug
Components: State Backends, Checkpointing
Affects Versions: 1.2.0
Reporter: Stephan Ewen
Priority: Blocker
Fix For: 1.3.0, 1.2.2
The Checkpoint Store retains the *n* latest checkpoints.
Savepoints are counted as well, meaning that for settings with 1 retained checkpoint, there are sometimes no retained checkpoints at all, only a savepoint.
That is dangerous, because savepoints must be assumed to disappear at any point in time - their lifecycle is out of control of the CheckpointCoordinator.
