Mahalo is currently testing Cassandra as an alternative data store to MySQL for certain pieces of our data. We are close to production which would see a move of 15 million rows from one table into a cluster which we hope will increase speed and allow us to scale the data as it grows more easily than on MySQL. We also have a short url product and would like to move its stats collecting data to Cassandra as well, to do this we would love an incr/decr feature like memcache/memcachedb has. I'm not sure if this is outside of the scope of Cassandra or not, but I did notice on this list it was requested before but thought I'd reitterate again in hopes it gets into the feature list.
