Citus is a PostgreSQL extension that transforms Postgres into a distributed database, so you can achieve high performance at any scale. With Citus, you extend your PostgreSQL database with new superpowers. Distributed tables are sharded across a cluster of PostgreSQL nodes to combine their CPU, memory, storage and I/O capacity. References tables are replicated to all nodes for joins and foreign keys from distributed tables and maximum read performance. Distributed query engine routes and parallelizes SELECT, DML, and other operations on distributed tables across the cluster. Columnar storage compresses data, speeds up scans, and supports fast projections, both on regular and distributed tables. You can use these Citus superpowers to make your Postgres database scale-out ready on a single Citus node.
Features
- Build a large cluster capable of handling high transaction throughputs
- Run fast analytical queries
- Process large amounts of time series or IoT data for real-time analytics
- You can easily add more worker nodes to the cluster and rebalance the shards
- Since Citus is an extension to Postgres, you can use Citus with the latest Postgres versions
- Citus works seamlessly with the PostgreSQL tools and extensions you are already familiar with
