I should just point out that MySQL supports replication and
transactional tables. With replication, each instance may be
a slave of at most one master. That limits the topology, but
still allows flexibility, e.g.

 - one server for updates and N servers for queries (star)
 - two update/query servers each slaved off the other (binary system)
 - N update/query servers each slaved off its neighbour (ring)
