[Download the slide to get the entire talk in the form of presentation note embedded in the ppt] Apache ZooKeeper is the chosen leader in distributed coordination. In this talk, I have explored the atomic elements of Apache ZooKeeper, how it fits everything together and some of its popular use cases. For ZooKeeper simplicity is the key and as a consumer of the API, our imagination enables us to push the limits of the ZooKeeper world.

So we're running Apache ZooKeeper. Now What? By Camille Fournier Hakka Labs
The ZooKeeper framework was originally built at Yahoo! to make it easy for the company’s applications to access configuration information in a robust and easy-to-understand way, but it has since grown to offer a lot of features that help coordinate work across distributed clusters. Apache Zookeeper became a de-facto standard for coordination service and used by Storm, Hadoop, HBase, ElasticSearch and other distributed computing frameworks.
Concurrency is hard. Consistency in distributed systems is hard. And then the whole thing should be highly-available and error resilient.
Fear not, there are good news: There exists an awesome tool called ZooKeeper to help you with this. There even exists a plethora of Python libraries for it, but how to know what to use and how?
This talk will walk you through ZooKeeper and how to use it with Python. We’ll be focusing on what I think is the most prominient ZooKeeper library out there for Python: Kazoo.
You’ll see how to do things in ZooKeeper and how to implement them using Kazoo. We’ll also peek in to the recipes Kazoo offers, and if we have enough time, touch a real life application we’ve used Kazoo and ZooKeeper to build at Spotify.

Client C1 writes the first version of /config
Client C2 reads /config and writes the second version
Client C1 tries to write a change to /config,
but the request fails because the version does not match
