Azure Database for PostgreSQL Hyperscale (Citus)

Citus Data was founded 9 years ago to change what’s possible with Postgres

Scaling out your Postgres database horizontally Each node has PostgreSQL with Citus installed. Each shard [ ] is 1 PostgreSQL table. Coordinator sends DMS/DDL queries to selective worker nodes. Coordinator node

Azure PostgreSQL for PostgreSQL Hyperscale (Citus) • PostgreSQL database with data and queries distributed across nodes to provide unlimited horizontal scalability • Shard your PostgreSQL database across multiple nodes to give your application more memory, compute, and • Powered by the open source Citus extension and managed by Azure

Microsoft Windows team relies on Citus and Postgres (on Azure) for mission- critical shiproom decisions “Distributed PostgreSQL is a game changer. We can support more than 6M queries every day, on 2 PB of data. With Citus, most of our queries respond in less than 0.2 seconds.” aka.ms/blog-petabyte-scale-analytics

Citus helps ASB onboard customers 20x faster “After migrating to Citus, we can onboard Vonto customers 20X faster, in 2 minutes vs. the 40+ minutes it used to take. And with the launch of Hyperscale (Citus) on Azure Database for PostgreSQL, we are excited to see what we can build next on Azure.”
