ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. All of these kinds of services are used in some form or another by distributed applications. This meeting is for users and developers. Discussions will be around roadmap, any issues users are having, and to help plan for the next release. Definitely come if you're a current user of ZooKeeper; or if your company has plans for a huge data store and you're evaluating solutions.
