> Externalized checkpoints are cleaned up when the job is suspended. Suspensions happen on graceful shut down (non-HA) or loss of leadership (HA).
> In case of HA, the checkpoint store does not clean up any checkpoints as they might be recovered by a new leader. The only way to stop a HA job is to actually cancel it. Therefore the configured clean up behaviour doesn't matter.
> In case of non-HA, suspensions happen because of graceful shut down (for example stopping a YARN session). In this case I would treat the clean up behaviour similar to cancelling the job.
> {code}
> ExternalizedCheckpointCleanup.DELETE_ON_CANCELLATION => delete on suspension
> ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION => retain on suspension
> {code}
