Shashikant Banerjee created RATIS-801:
-----------------------------------------
Summary: Ratis snapshot should consider stateMachine#appliedIndex
for triggering snapshot
Key: RATIS-801
URL: https://issues.apache.org/jira/browse/RATIS-801
Project: Ratis
Issue Type: Improvement
Affects Versions: 0.5.0
Reporter: Shashikant Banerjee
Assignee: Shashikant Banerjee
Fix For: 0.5.0
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.
