    Description

      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.
