Mirza Aliev updated IGNITE-27725:
---------------------------------
Description:
h3. Motivation
We would like to add some logs to Placement Driver and around, so we could
properly catch rare case when Placement Driver wasn't registered after
metastorage leader re-election and random nodes restarts.
* We have added logs to the most suspicious place --
{{LogicalTopologyEventListener#onTopologyLeap}}. This method wasn't even
implemented, meaning that if some node is lagging in terms of CMG raft group,
and rejoins after some time, it won't receive
{{LogicalTopologyEventListener#onNodeJoined}}, but {{onTopologyLeap}}, hence
all logic with node subscription will be missed. The first step is to log the
place and it must be fixed as soon as possible
https://issues.apache.org/jira/browse/IGNITE-27770
* Proper logging of {{LeaseTracker}} start and stop
* Starting Ragt client in {{PlacementDriverManager}}, receiving leader change
event.
etc.
