             Summary: Single partition queries can mistakenly omit partition deletions and resurrect data
                 Key: CASSANDRA-15690
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15690
             Project: Cassandra
          Issue Type: Bug
            Reporter: Aleksey Yeschenko
            Assignee: Sam Tunnicliffe


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.
