Shawn Kumar updated CASSANDRA-7486:
-----------------------------------
Description:
See
http://www.slideshare.net/MonicaBeckwith/garbage-first-garbage-collector-g1-7486gc-migration-to-expectations-and-advanced-tuning
and https://twitter.com/rbranson/status/482113561431265281
May want to default 2.1 to G1.
2.1 is a different animal from 2.0 after moving most of memtables off heap.
Suspect this will help G1 even more than CMS. (NB this is off by default but
needs to be part of the test.)
