sivabalan narayanan commented on HUDI-6547:
-------------------------------------------
Myself, surya and Prashanth jammed over this. This sequence of events may not
be possible. bcoz, a completed a commit can never be rolled back unless in
restore cases. and we will never schedule a log compaction if we find any
pending commits prior to that. So, this sequence may not happen
> Rollback of older deltacommit fails after a log compaction commit
