Test for RBS scenario #8639

Open ttyusupov opened 3 years ago

ttyusupov commented 3 years ago

Jira Link: DB-3992

Follower (n3) is partitioned away / offline
Split hapenned
Leader (n1) GCed Raft log, so n3 can't catch up Raft log
n3 tablet replica is deleted and RBS started
Will n3 create child tablets? When?
Might be we don't need to RBS the parent tablet in this case and just RBS child ones? Can child tablets contain non-relevant parent data that we want to avoid downloading?

Another scenario: variation of TabletSplitExternalMiniClusterITest.ReplaceNodeForParentTablet, but turn on back offline TS after moving parent tablet to TS-4 and make sure everything is OK (including each tablet has 3 replicas).

@basavaraj29 , can you check with @amitanandaiyer and see if there are existing tests around this space. If not, we need to add the above. cc @ttyusupov
