Citus Documentation
Welcome to the documentation for Citus 13.0! Citus is an open source extension to PostgreSQL that transforms Postgres into a distributed database. To scale out Postgres horizontally, Citus employs distributed tables, reference tables, and a distributed SQL query engine. The query engine parallelizes SQL queries across multiple servers in a database cluster to deliver dramatically improved query response times, even for data-intensive applications.
Learn the Citus architecture, install locally,
and follow some ten-minute tutorials.
See how Citus allows multi-tenant applications
to scale with minimal database changes.
