----------------------------------------
Assignee: Alexander Lapin
> Remove obsolete leases
> ----------------------
>
> Key: IGNITE-21106
> URL: https://issues.apache.org/jira/browse/IGNITE-21106
> Project: Ignite
> Issue Type: Bug
> Reporter: Alexander Lapin
> Assignee: Alexander Lapin
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> h3. Motivation
> Occurred that obsolete leases (expired leases for removed replication groups)
> aren't dropped themselves. Despite the fact that it's generally a leak and
> thus incorrect, some tests like ItSqlLogicTest may suffer from this.
> h3. Definition of Done
> Obsolete leases are removed from the meta storage and thus no longer
> processed.
> h3. Implementation Notes
> I believe that
> {code:java}
> // Remove all expired leases that are no longer present in assignments.
> renewedLeases.entrySet().removeIf(e ->
> e.getValue().getExpirationTime().before(now)
> && !currentAssignmentsReplicationGroupIds.contains(e.getKey()));{code}
> in
> {code:java}
> org.apache.ignite.internal.placementdriver.LeaseUpdater.Updater#updateLeaseBatchInternal{code}
> should do the trick.
