We are keeping an eye on Cassandra with a view to using it in a large-scale audit data application. Currently I don't think it does quite what we want but I'm still very impressed with what it does do.
We're not yet at the stage of really properly evaluating it for production use, but I have had a play but only with up to 4 nodes on VMs with little data. To evaluate it properly I'd need to try it with a lot more nodes on real hardware with a lot of data; this would require considerable motivation from the business to loan me the kit (and spare my time from other activities, of course) I'd like to see * More ideas / solutions for the load balancing problem (all my data goes into a few nodes) - I understand this quite well but find it very difficult to explain to others * Bulk delete operations such as the proposed remove_range - or a method of supplying a timestamp to delete rows after. This is essential for efficient data purging. But rather a lot of the things that I wanted from 0.3 have been done already, thanks. Mark
