Mirza Aliev updated IGNITE-27770:
---------------------------------
Description: {{LogicalTopologyEventListener#onTopologyLeap}} is not
implemented in {{TopologyAwareRaftGroupService}}, 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 subscriptions will be missed. (was:

place and it must be fixed as soon as possible)
