Vladislav Pyatkov updated IGNITE-21258:
---------------------------------------
Description:
h3. Motivation
We seek to decrease the load on the metastorage thread because when the MC
thread is holding, it blocks the handling of other events.
{code}
placementDriver.listen(PrimaryReplicaEvent.PRIMARY_REPLICA_ELECTED,
this::onPrimaryReplicaElected);
placementDriver.listen(PrimaryReplicaEvent.PRIMARY_REPLICA_EXPIRED,
this::onPrimaryReplicaExpired);
{code}
Currently, both primary replica events are handled on the MC thread, though the
striped executer is a well-suited place to do it.
h3. Definition of done
Move handling of the primary replica events (PRIMARY_REPLICA_ELECTED,
PRIMARY_REPLICA_EXPIRED) in the striped pool.
