Accelerating PostgreSQL with ReadySet Caching
Disclaimer: The opinions expressed in this article are my own and do not necessarily reflect the views of my employer. This tutorial demonstrates how to use ReadySet as a caching layer for PostgreSQL databases. ReadySet is a wire-compatible caching solution that sits between your application and database, providing sub-millisecond query performance without requiring code changes. Why Cache PostgreSQL? PostgreSQL is the world's most advanced open-source relational database, widely used for transactional workloads. Whether you're running PostgreSQL on-premises, in the cloud, or using a managed service, every query incurs: Network round-trip latency – Depending on region and network conditions (e.g., 14ms from a client in New Jersey to a cluster in AWS us-east-1) Query processing overhead – Parsing, planning, and execution on the database server Result serialization – Packaging and transmitting results back to your application For read-heavy workloads with repetit...
