---------------------------------------
[~StephanEwen] is this a blocker for the 1.3 release?
> 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.
