We're using Cassandra in development to store custom index information  
on large document sets. Also considered HBase and Voldemort.  
Cassandra's data model and performance tradeoffs seemed to best fit  
our needs.

Features that we're looking forward to seeing:
* map/reduce integration
* built-in counters with incr/decr
* more automated load balancing
