Jonathan Ellis created CASSANDRA-4292:
-----------------------------------------
Summary: Per-disk I/O queues
Key: CASSANDRA-4292
URL: https://issues.apache.org/jira/browse/CASSANDRA-4292
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Jonathan Ellis
Priority: Minor
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.
