[jira] [Updated] (FLINK-4511) Schedule periodic savepoints
[ https://issues.apache.org/jira/browse/FLINK-4511?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Aljoscha Krettek updated FLINK-4511:
------------------------------------
Issue Type: New Feature (was: Sub-task)
Parent: (was: FLINK-4484)
> Schedule periodic savepoints
> ----------------------------
>
> Key: FLINK-4511
> URL: https://issues.apache.org/jira/browse/FLINK-4511
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / State Backends
> Reporter: Ufuk Celebi
> Priority: Major
>
> Allow triggering of periodic savepoints, which are kept in a bounded queue (like completed checkpoints currently, but separate).
> If there is no periodic checkpointing enabled, only periodic savepoints should be schedulded.
> If periodic checkpointing is enabled, the periodic savepoints should not be scheduled independently, but instead the checkpoint scheduler should trigger a savepoint instead. This will ensure that no unexpected interference between checkpoints and savepoints happens. For this, I would restrict the savepoint interval to be a multiple of the checkpointing interval (if enabled).
