Joshua Harlow df067e974c Add new eventlet docs + a few other tweaks to the index.rst

Explain what the new eventlet handler is and how it can be
used (with api docs as well) and links some of the items in
index.rst to targets (and makes the irc link clickable).

kazoo

Kazoo is a Python library designed to make working with Zookeeper a more hassle-free experience that is less prone to errors.

Kazoo features:

A wide range of recipe implementations, like Lock, Election or Queue
Data and Children Watchers
Simplified Zookeeper connection state tracking
Unified asynchronous API for use with greenlets or threads
Support for gevent 0.13 and gevent 1.0
Support for eventlet
Support for Zookeeper 3.3 and 3.4 servers
Integrated testing helpers for Zookeeper clusters
Pure-Python based implementation of the wire protocol, avoiding all the memory leaks, lacking features, and debugging madness of the C library

Kazoo is heavily inspired by Netflix Curator simplifications and helpers.

Note

You should be familiar with Zookeeper and have read the Zookeeper Programmers Guide before using kazoo.

Why

Using Zookeeper in a safe manner can be difficult due to the variety of edge-cases in Zookeeper and other bugs that have been present in the Python C binding. Due to how the C library utilizes a separate C thread for Zookeeper communication some libraries like gevent (or eventlet) also don't work properly by default.

By utilizing a pure Python implementation, Kazoo handles all of these cases and provides a new asynchronous API which is consistent when using threads or gevent (or eventlet) greenlets.

Source Code

All source code is available on github under kazoo <https://github.com/python- zk/kazoo>.

Bugs/Support

Bugs should be reported on the kazoo github issue tracker.

The developers of kazoo can frequently be found on the Freenode IRC network in the \#zookeeper channel.
