Subject trying to use row_cache (b/c we have hot rows) but nodetool info says zero requests
Date Wed, 16 Jan 2013 18:33:13 GMT
We have quite wide rows and do a lot of concentrated processing on each I thought I'd try the row cache on one node in my cluster to see
if I could detect an effect of using it.

The problem is that nodetool info says that even with a two gig row_cache
we're getting zero requests.  Since my client program is actively
processing, and since keycache shows lots of activity I'm puzzled.

Shouldn't any read of a column cause the entire row to be loaded?

My entire data file is only 32 gig right now so its hard to imagine the 2
gig is too small to hold even a single row?

Any suggestions how to proceed are appreciated.
