Thank you everyone for your input.
My dataset is ~100G of size with 1 or 2 read intensive column families. The
cluster has plenty of RAM. I'll start off small with 4G of row cache and
monitor the success rate.

My experience has been that the row cache is much more effective.
However, reasonable row cache sizes are so small relative to RAM that I
don't see it as a significant trade-off unless it's in a very memory
constrained environment. If you want to enable the row cache (a big if)
you probably wa
Our experience is that you want to have all your very hot data fit in the row
cache (assuming you don’t have very large rows), and leave the rest for the OS.
Unfortunately, it completely depends on your access patterns and data what is
the right size for the cache - zero makes sense for a lot
Hello list,
I was if anyone has any pointers or some advise regarding using row cache
vs leaving it up to the OS buffer cache.
I run cassandra 1.1 and 1.2 with JNA, so off-heap row cache is an option.
Any input appreciated.
