Citus vs. Single-Node Postgres Database | A Side-by-Side Comparison
In this demo of the Citus database, engineer Marco Slot shines a light on the performance of the Citus extension to PostgreSQL, and the benefits of scaling out Postgres horizontally. Citus is available as open source, as a fully-managed database as a service, and as enterprise software that can be run anywhere. Today Citus is often used by SaaS teams building multi-tenant applications, as well as developers building real-time analytics applications that need sub-second response times across billions of records.
Marco showed the original version of this demo in a keynote at PostgresOpen Silicon Valley. People found it so useful that we decided to retool it and share more broadly. The Citus database cluster that Marco creates to compare against a regular Postgres node is a 4-node Citus database cluster with 244GB total RAM and 32 vCPUs, hosted in Citus Cloud (that’s our managed database as a service.)
