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?
