I started exploring apache cassandra 1.1.3. I am facing problem with how to
improve performance of cassandra using caching configurations.
I tried setting following configurations:
./nodetool -h 107.108.189.204 setcachecapacity DemoUser Users 25 0
./nodetool -h 107.108.189.204

http://www.datastax.com/dev/blog/caching-in-cassandra-1-1 for
background.
