Benedict commented on CASSANDRA-6843:
-------------------------------------
Rebased patch
[here|https://github.com/belliottsmith/cassandra/tree/6843-offheap.gc]
Some quick and dirty benchmarks show that this patch moves the bottleneck for
overwrite workloads to the commit log, giving a 2x+ performance boost, with
more to be had once we compress the commit log.
