What is ReadySet?

ReadySet is a lightweight SQL caching engine that sits between your application and Postgres or MySQL database and turns even the most complex SQL reads into lightning-fast lookups. Unlike other caching solutions, ReadySet keeps the cache up-to-date automatically and requires no changes to your application code.

Based on years of dataflow research at MIT¹, ReadySet stores the results of queries in-memory and automatically keeps these results up-to-date as the underlying database changes. ReadySet can do this automatically because it listens to your database’s replication stream.

This means:

• No extra code to keep your cache and database in sync
• No extra code to evict stale records
• No TTLs to set – your cache is as up-to-date as your replication lag

ReadySet is wire-compatible with MySQL and Postgres.
