Jonathan Ellis updated CASSANDRA-863:
-------------------------------------
Attachment: 863-v2.txt
v2 -- change default keys cached to 200k, move examples of overriding that in
sample config to CFs not used by stress test, and make Super1 BytesType so
stress performance isn't artificially worse than standard1 from the comparator
> Default cache levels should be explicit, not percentage
> -------------------------------------------------------

> 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.
