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. 

Cheers
