Matt Stump commented on CASSANDRA-8150:
---------------------------------------
2.1 is production ready. We've got a number of DataStax customers using G1 with
both 2.0.X and 2.1.X. Some of the comments in CASSANDRA-7486 are a direct
result of those experiences.

> It's been found that the old twitter recommendations of 100m per core up to
> 800m is harmful and should no longer be used.
> Instead the formula used should be 1/3 or 1/4 max heap with a max of 2G. 1/3
> or 1/4 is debatable and I'm open to suggestions. If I were to hazard a guess
> 1/3 is probably better for releases greater than 2.1.
