Subject [jira] Created: (CASSANDRA-863) Default cache levels should be explicit, not percentage

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.
