CouchDB will enforce unique docids within a database on a single node.
In the long run, we may also support partitioning a single database
across many nodes. In that case, we should also support uniqueness
constraints with a single logical database. So should your name server
get too busy for one box, Couch should support spreading the load
across a cluster of boxes.
