Denis Chudov updated IGNITE-21325:
----------------------------------
Description:
Motivation
No processing of any transactional request should be started when the event
processing of PRIMARY_REPLICA_EXPIRED event is in progress. The reason is that
such requests may try to acquire transactional locks on the current primary
replica, and the locks acquired during the previous lease are released by the
listener of PRIMARY_REPLICA_EXPIRED event. The validity of the current primary
is checked in {{{}PartitionReplicaListener#ensureReplicaIsPrimary{}}}.
We must ensure that this method is called after the processing of
PRIMARY_REPLICA_EXPIRED event. The future returned by
{{PlacementDriver#previousPrimaryExpired}} can be used for this.
Definition of done
The processing of transactional requests for the current primary replica can't
be started before the processing of PRIMARY_REPLICA_EXPIRED event finishes.
