Yuan Mei commented on FLINK-4511:
---------------------------------

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.

> 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).
