------------------------------------------
Summary: Do not process absent groups in cluster in lease updater
Key: IGNITE-23857
URL: https://issues.apache.org/jira/browse/IGNITE-23857
Project: Ignite
Issue Type: Improvement
Reporter: Vladislav Pyatkov
h3.Motivation
We are getting rid of expired leases (for removed replication groups) in the
common cycle of maintenance of the leases.
> LeaseUpdater.Updater#updateLeaseBatchInternal
In a case when all replication groups are removed, we add this code to no miss
update:
{code}
boolean emptyAssignments =
aggregatedStableAndPendingAssignmentsByGroups.isEmpty();
if (renewedLeases.isEmpty() && (!emptyAssignments ||
leasesCurrent.leaseByGroupId().isEmpty())) {
LOG.debug("No leases to update found.");
return;
}
{code}
We can simplify the condition:
{code}
renewedLeases.isEmpty()
{code}
but in this case we will store expired leases until the new one does not appear.
h3.Definition of done
Make the condition simpler.
