Readyset is a transparent SQL caching layer for PostgreSQL and MySQL. It sits in front of your existing database to accelerate queries and scale read throughput horizontally, without requiring application code rewriting or manual cache invalidation management.

Under the hood, Readyset caches selected SELECT query results and updates them incrementally as underlying data changes. To do this, it leverages your database's replication stream, ensuring results stay synchronized with the source — no more stale caches.

Compatible at the wire protocol level for Postgres and MySQL, Readyset works with your current ORM or database client and serves cached queries with sub-millisecond latency, with no application code changes. Managed by DINAO, it is installed, tuned, and monitored on a French infrastructure, with backups and updates included.
