Mukul Kumar Singh commented on RATIS-801:
-----------------------------------------
[~bharat], I feel it will be great addition to have StateMachine having the
ability to trigger snapshots. Can we add a shouldTakeSnapshot() methods to
StateMachine . ?
> Ratis snapshot should consider stateMachine#appliedIndex for triggering
> snapshot

> Currently, while triggering snapshot, snapshotUpdater#appliedIndex is taken
> into account to decide whether it has exceeded the snapshot threshold from
> the last snapshotIndex. This may lead to creating more snapshots than usual
> as stateMachineUpdater#appliedIndex is updated as soon as the
> applyTransaction call happens. Ideally, Ratis snapshot should nbe triggered
> taking stateMachine's applied index into account.
