Jonathan Ellis commented on CASSANDRA-840:
------------------------------------------
What problem is the table locking trying to solve? Just concurrent access to
columnFamilyStores_? If it is that then using a NBHM instead should be
cleaner. I've always intended to refactor CFS to have a Table reference rather
than a Table String.
> Add the ability to add/remove/rename column families on a single node.
