Subject Re: cassandra key cache question
Date Thu, 27 Sep 2012 09:58:52 GMT
Hi!
One more question:
I have couple of dropped column families, and in the JMX console I don't
see them under org.apache.cassandra.db.ColumnFamilies, *BUT *I do see them
under org.apache.cassandra.db.Caches, and the cache is not empty!
Does it mean that Cassandra still keep memory busy doing caching for a
non-existing column family? If so, how do I remove those caches?

Thanks!
