Subject key cache size calculation
Date Mon, 02 Apr 2012 23:24:10 GMT
Hi guys,

We are calculating key cache size right now. There is this column family
with ~ 100 million columns and right now we have the cache size set at 2
million.

I suspect that the active data we got is not all fitting in the 2 million
cache size and we at times are getting query execution time way higher then
the normal. Is there a limit to key cache size? I know that is all taken
from heap but how much max we can go with setting the key cache sizes?

cheers,
Shoaib
