Hi Jonathon, I'd say I am at the evaluation stage. The only reason I am looking at nosql type applications instead of using mysql is the vain hope my application will one day scale to the point that mysql won't be the best option. Cassandra appears to be the best fit for the requirement I have that everything must scale horizontally.
The information I will store will be user accounts, user configuration options, and other small data sets to start. Eventually, the largest implementation will be comments functionality on urls for a search engine interface I am building. The only things i'd like to see is the atomic operations discussed a while back, and an easier interface for python. Honestly the latter can be built on top of thrift ( lazyboy is one attempt ) so I could just write it myself, but you did ask.

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.
