Brandon Williams updated CASSANDRA-10505:
-----------------------------------------
Reproduced In: 2.1.8
2.1.8 is where the original problem occurred, but the compaction issue still
remains on 2.1 HEAD.
> Duplicate range tombstones
> --------------------------

> Key: CASSANDRA-10505
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10505
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Brandon Williams
> Fix For: 2.1.x
>
>
> I don't have a way to reproduce this just yet, but I have the sstables to
> prove it and can provide those offline. What I can reproduce, however, is
> the magnification of this problem via compaction. Here's what I know so far:
> * under some condition, we flush the exact same RT more than once in the same
> sstable. Same timestamps, everything.
> * Once this happens in multiple sstables, compacting them causes the
> duplication to grow. The more this occurs, the worse the problem gets.
> This continues until gc_grace has passed, then they are all evicted normally.
> I'd at least like to take a look at the compaction amplification for now,
> that way if the condition does occur, at least compaction can help it, rather
> than exacerbate it.
