I've refreshed my memory about the issue and the proposed patch. Looks like we didn’t reach a clear agreement on how to resolve the problem. The patch is about introducing a configurable limit to the number of ephemeral znodes, while @kezhu suggested [1] to get rid of fuzzy snapshots based on [2].
#1716 has a -1 from @eolivelli, so I cannot immediately merge it. Can we come back to this problem as a team and discuss how to move forward? Is there anybody who’s willing to work on ZOOKEEPER-4874? Do you think ZOOKEEPER-4874 would be acceptable to backport to branch-3.9?
