Default cache levels should be explicit, not percentage
-------------------------------------------------------
Key: CASSANDRA-863
URL: https://issues.apache.org/jira/browse/CASSANDRA-863
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 0.6
Reporter: Brandon Williams
Assignee: Brandon Williams
Priority: Trivial
Fix For: 0.6
Now that we can specify explicit numbers for row and key caches, the default
config should use this. The reason is that it's very easy to grow your keys
and not realize a percentage is going to get you eventually. It's better to
have a system that has a low cache hit rate and keeps going than a system that
encounters memory pressure from overpopulating its cache and slows to a crawl
or dies.
