Fix Version/s: 1.1.1
My goal is to make truncate to be less IO intensive so that my junit tests run faster (as already explained in
CASSANDRA-3710). I think I have now a solution which does not change too much:
I created a patch that optimizes three things within truncate:
- Skip the whole Commitlog.forceNewSegment/discardCompletedSegments, if durable_writes are disabled for the keyspace.
CASSANDRA-3710implemented, truncate does not need to flush memtables to disk when snapshots are disabled.
- Reduce the sleep interval
The patch works nicely for me. Applying it and disabling durable_writes/autoSnapshot increased the speed of my testsuite vastly. I hope I did not overlook something.
Let me know if my patch needs cleanup. I'd be glad to change it, if it means the patch will get accepted.
