------------------------------------------------------------
There is a re-architect related to savepoint and checkpoint.
Do not think periodic savepoint can benefit too much if it is purely user-owned
(triggered)
And do not know why periodic checkpoint is not enough.
Close this as no intention in this direction.

> Project: Flink
> Issue Type: New Feature
> Components: Runtime / State Backends
> Reporter: Ufuk Celebi
> Priority: Minor
> Labels: auto-deprioritized-major, stale-minor
>
> 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).
