ZK provides all of the coordination you need for this problem, but you
should store your data elsewhere.
Any key-data store with decent read-write speed will suffice. Memcache
would be reasonable for that if
you don't need persistence in the presence of failure. Voldemort would be
another alternative if you do
Couchdb is generally pretty slow as a key/value store and is probably not a
very good option for this.
