> Is there any way I can configure KeyCahce to use Non-Heap memory ? No. You could add a feature request here https://issues.apache.org/jira/browse/CASSANDRA
Could you post some stats on the current key cache size and hit rate ? (from nodetool info) It would be interesting to know how many keys it contains Vs the number of rows on the box and the hit rate.
