[~carlyeks] to review since we were poking this in CASSANDRA-10829
> Parallel cleanup can lead to disk space exhaustion
> --------------------------------------------------
>
> Key: CASSANDRA-11179
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11179
> Project: Cassandra
> Issue Type: Improvement
> Components: Compaction, Tools
> Reporter: Tyler Hobbs
> Assignee: Marcus Eriksson
> Fix For: 2.1.x, 2.2.x, 3.0.x, 3.x
>
>
> In CASSANDRA-5547, we made cleanup (among other things) run in parallel
> across multiple sstables. There have been reports on IRC of this leading to
> disk space exhaustion, because multiple sstables are (almost entirely)
> rewritten at the same time. This seems particularly problematic because
> cleanup is frequently run after a cluster is expanded due to low disk space.
> I'm not really familiar with how we perform free disk space checks now, but
> it sounds like we can make some improvements here. It would be good to
> reduce the concurrency of cleanup operations if there isn't enough free disk
> space to support this.
