Date Fri, 30 Aug 2013 11:46:54 GMT


Chris Burroughs commented on CASSANDRA-5821:

>  You probably are not asking for the count and only for better internal handling, right?

Yep, just looking for better handling.  Although if mappingCount() or any other new introspection
methods were available we would probably expose them.
