I'm definitely a database noob so I'm looking for correction -- but isn't
the main advantage of CouchDB / Tokyo Cabinet etc. that it's much simpler to
spread them horizontally across multiple machines in a similar fashion to
memcache? From what I understand, the main problem with MySQL / other
traditional databases is that the complexity of your architecture increases
dramatically as you go scale beyond one server as you have to deal with all
sorts of problems with data replication whereas with CouchDB, it's much more
straightforward to spread the data around. Is that correct?
