ZooKeeper is a high-performance coordination service for distributed applications. It exposes common services - such as naming, configuration management, synchronization, and group services - in a simple interface so you don't have to write them from scratch. You can use it off-the-shelf to implement consensus, group management, leader election, and presence protocols. And you can build on it for your own, specific needs. If you are upgrading from version 2.2.1 on SourceForge be sure to review the 3.0.1 release notes for migration instructions.

In ZooKeeper version 3 watches are re-registered when the client reconnects to a server. See this section of the docs: http://hadoop.apache.org/zookeeper/docs/r3.0.1/zookeeperProgrammers.html#ch_zkWatches Specifically this: "Watches will not be received while disconnected from a server. When a client reconnects, any previously registered watches will be reregistered and triggered if needed." I have created a jira to improve these docs: https://issues.apache.org/jira/browse/ZOOKEEPER-253 Thanks for bringing this to our attention!

Also, nothing says that some other client won't change the node immediately after you change it. You can access the version using zoo_exists or zoo_get - specifically the "struct Stat stat" argument of either of those methods contains a "version" member.

I agree that I can use zoo_exists and zoo_get to get the version of the znode as it exists currently. The problem I am trying to solve is that getting the version from struct Stat in either zoo_exists or zoo_get may not be the same version that my last successful zoo_set used. I would like to get the version that denotes my last successful zoo_set() operation to a particular znode. I understand that the data and version to the znode may change immediately one or multiple times after my zoo_set() and this is fine, but I would still like to know the znode's versions of the data I set.
