Matt Stump created CASSANDRA-8150:
-------------------------------------
Summary: Simplify and enlarge new heap calculation
Key: CASSANDRA-8150
URL: https://issues.apache.org/jira/browse/CASSANDRA-8150
Project: Cassandra
Issue Type: Improvement
Components: Config
Reporter: Matt Stump
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.
