Citus & Patroni: The Key to Scalable and Fault-Tolerant PostgreSQL | Citus Con 2023

Video recording of Alexander Kukushkin’s conference talk at Citus Con 2023 about Citus & Patroni, the key to scalable and fault-tolerant PostgreSQL. The Citus database is an open source extension to PostgreSQL that enables you to scale out 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.
This talk covers implementation details of Patroni & Citus integration, and includes a demo of cluster deployment and maintenance on Citus worker nodes without interrupting client connections.
Alexander Kukushkin is well known in the PostgreSQL community as a Patroni expert. Besides Patroni, Alexander occasionally contributes to PostgreSQL and other open source projects and tools, usually Postgres related.
