Citus Documentation

Welcome to the documentation for Citus 10! 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.

As of version 10, Citus includes new ways to grow and scale your database, with the introduction of a new columnar storage feature and the ability to run on a single-node.
