from Wednesday 8 May to Friday 10 May 2019.

I'm a developer at Clever Cloud. I work with Scala and Rust most of the time. Database-wise, I'm a PostgreSQL fan. I like teaching stuff to my colleagues, both old timers and new comers.

Zookeeper in action

Tools-in-Action

While it's accepted to use ZooKeeper to manage databases clusters, it's a bit less common to use it for applications cluster. And quite frankly we think it's extremely sad as ZooKeeper saved us on certain business use cases. We will explain how we used it to spread out data processing in realtime on an application cluster with automatic scalability.

In other words, how do you assign a fraction of the data to each instance of your application in realtime when the number of instances can vary at any time. We will show you how we managed this for the monitoring and alerting of all the applications running on Clever Cloud, our public Platform as a Service.
