In Webex, we are using Cassandra for store User Feed & User Activity data, it was nearly real time, to support web user interactive, current was in early testing. We evaluated Voldemort, MemcacheDB, Dynomite.
I most want : 1. support build second index on values or columns. 2. support some kind of optimistic lock, base on row or columnfamily. 3. support increment/decrement. 2009/11/21 Jonathan Ellis <jbel...@gmail.com> > Hi all, > > I'd love to get a better feel for who is using Cassandra and what kind > of applications it is seeing.
