Description
As noted in CASSANDRA-809, we have a certain amount of flush (and compaction) threads, which mix and match disk volumes indiscriminately. It may be worth creating a tight thread -> disk affinity, to prevent unnecessary conflict at that level.
OTOH as SSDs become more prevalent this becomes a non-issue. Unclear how much pain this actually causes in practice in the meantime.
