Hi all, I'd love to get a better feel for who is using Cassandra and what kind of applications it is seeing. If you are using Cassandra, could you share what you're using it for and what stage you are at with it (evaluation / testing / production)? Also, what alternatives you evaluated/are evaluating would be useful. Finally, feel free to throw in "I'd love to use Cassandra if only it did X" wishes. :)
I can start: Rackspace is using Cassandra for stats collection (testing, almost production) and as a backend for the Mail & Apps division (early testing). We evaluated HBase, Hypertable, dynomite, and Voldemort as well. Thanks, -Jonathan (If you're in stealth mode or don't want to say anything in public, feel free to reply to me privately and I will keep it off the record.)
