Subject Re: key cache size

This is the key cache entry 
https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/cache/KeyCacheKey.java

Note that the Descriptor is re-used. 

If you want to see key cache metrics, including bytes used,  use nodetool info.

What would be the overhead for this key in the key cache ?
