By default, return u64::MAX, which means no extra waiting is needed before commiting;
get max committable checkpoint, for handlers that want to wait for some condition before commiting,
one use-case is the objects snapshot handler,
which waits for the lag between snapshot and latest checkpoint to reach a certain threshold.
