There was a problem hiding this comment.
we should clean this up in master once backported. can you put a comment in there?

The build failure was regarding refresh listeners. I don't think it's a related but probably signals a concurrency bug. I tried to reproduce this without success (I run ~300 time). Capturing the info here in case it's needed. |
Similar assertion recently failed on master (#24418 (comment)), so looks to be unrelated to your changes here |

The assertion `assertOpsOnPrimary` does not store seq_no and primary term of successful deletes to the `lastOpSeqNo` and `lastOpTerm`. This leads to failures of the subsequence CAS deletes or indexes with seq_no and term. Moreover, this assertion trips a translog assertion because it bumps the primary term of some operations but not the primary term of the engine. Relates elastic#36467 Closes elastic#37684

PS there are still discussions about the parameter naming. I'll rename these once we have settled on something.
