Citus is an open source extension to PostgreSQL that enables you to scale out your database horizontally by sharding your data across many nodes, and Patroni is an open source tool for managing and automating PostgreSQL High Availability. Combined together three open source projects become a superhero – a scalable PostgreSQL cluster with self-healing capabilities.
In my presentation I will cover implementation details of Patroni & Citus integration, and do a live-demo of cluster deployment and showcase maintenance on Citus worker nodes without interrupting client connections.
