<h1>ZooKeeper: Because Coordinating Distributed Systems is a Zoo</h1>
<div id="front-matter"></div>
<p>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.
</p>
<p>
The following documents describe concepts and procedures to get
you started using ZooKeeper. If you have more questions, please
ask the <a href="http://hadoop.apache.org/zookeeper/mailing_lists.html">mailing list</a> or browse the
archives.
