1. readyset

   1 25 4,896 9.8 Rust

   Readyset is a MySQL and Postgres wire-compatible caching layer that sits in front of existing databases to speed up queries and horizontally scale read throughput. Under the hood, ReadySet caches the results of cached select statements and incrementally updates these results over time as the underlying data changes.

   I also faced similar issues and was looking for easy ways to improve performance in our application when I came across an awesome tool called Readyset. It sits between your application and database, intelligently caching complex queries while automatically handling invalidation. This setup can significantly boost performance without requiring major changes to your existing infrastructure.
