Subject [jira] [Commented] (CASSANDRA-9896) Add ability to disable commitlog recycling
Date Mon, 27 Jul 2015 20:08:05 GMT


Brandon Williams commented on CASSANDRA-9896:

Here's a comparison of 1ms with 64 concurrent writes, 2.0.15, and a patch given to me by a
third party that removes the sleep, with a smaller size (1k vs 64k):

That patch performs significantly better, so I'm less certain that disabling the commitlog
recycling is the best solution, but obviously helps.  You can see the patch [here|]

> See CASSANDRA-9533 for background, specifically the graphs I linked.  Benedict suggests
this is due the commitlog recycling and I agree, so the simplest solution is to be able to
disable that.
