There's an
old_parts_lifetime
setting (8 minutes by default) which delays the removal of stale parts. How is the race condition possible if the test execution time is about 30-40 seconds, and it's much less than 8 minutes?
@tavplubix, the value of old_parts_lifetime
is randomized. In fact, in all the examples that I listed, old_parts_lifetime
is set to 10, making it possible for the race condition to manifest itself.

Well done @mstetsyuk, thanks! However, one thing is not clear:
However, because the test has a race condition with ReplicatedMergeTreeCleanupThread removing stale parts, the part log also includes RemovePart events.
