> We have logic that allows us to exclude sstables with partition deletions that are older than the minimum collected timestamp in a local request. However, it’s possible that another node could have rows that aren’t known to the local node that are in turn older than the excluded partition deletion. In such a scenario, those will be mistakenly resurrected, which is a correctness issue.
