Subject Re: What is substituting keys_cached column family argument
Date Thu, 06 Dec 2012 13:54:19 GMT
Rob,

Have you played with this I have many CFs, some big some small some using
large caches some using small ones, some that take many requests, some that
take a few.

Over time I have cooked up a strategy for how to share the cache love, even
thought it may not be the "best" solution to the problem I feel it makes
sense.

I can not figure out how I am going to be happy with global caches that I
do not control the size. What is your take on this?

Edward
