James Philips (Couchbase) quoted by Curt Monash:
NoSQL is simply a three-horse race between Couchbase, MongoDB, and Cassandra.
Off the top of my head I could name at least two other projects that are either having numerous deployments or are already managing huge amounts of data. And I’d bet every regular reader would figure out that I’m referring to Redis and HBase.
