Subject Re: Cassandra users survey
Date Fri, 20 Nov 2009 21:42:48 GMT
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.

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.



(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.)
