I was under the impression that Cassandra used concurrent mark and sweep (i.e. -XX:+UseConcMarkSweepGC) as the default setting.

- erichocean 14y agoI does, but that's still not pause-less, and it doesn't cover a "full" collection at all, just the intermediate ones. I get a full collection roughly once every 10 minutes. Until then, the pauses are only in the 20-30ms range (which is still double the usual latency for a request). With Azul Zing, the longest you'll ever see is the 20-30ms range, and it's virtually always around 1ms.
