Date: Tue, 04 May 2010 13:02:27 -0700 Message-ID: User-Agent: Gnus/5.110011 (No Gnus v0.11) Emacs/22.2.50 (darwin) MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii I have a ColumnFamily with a small number of keys, but each key has a large number of columns. What's the best way to get just the keys back? I don't want to load all the columns if I don't have to. There also isn't necessarily any column names in common between the different rows. Cheers, Chris Dean
