[Zookeeper-user] Scalability and ZooKeeper java client thread safety

[Anthony U. <ant...@gm...>]

I have a distributed server cluster and each of the many threads on
each server has a ZooKeeper java client used to communicate to other
machines.  What kind of scalability can I expect from the zookeeper
server?  Can I just add more QuorumServers infinitely?

Also, assuming I can coordinate the default watcher behavior of these
various threads, would it be safe to share the ZooKeeper objects
between them?
