kiebor81/mudis: Mudis is a fast, thread-safe, in-memory, sharded LRU cache for Ruby applications. Rails and Hanami (or any Rack) compatible.

Mudis is a fast, thread-safe, in-memory, sharded LRU (Least Recently Used) cache for Ruby applications. Inspired by Redis, it provides value serialization, optional compression, per-key expiry, and metric tracking in a lightweight, dependency-free package that lives inside your Ruby process. It’s ideal for scenarios where performance and process-local caching are critical, and where a full Redis setup is overkill or otherwise not possible/desirable. Alternatively, Mudis can be upscaled with higher sharding and resources in a dedicated Rails/Hanami/Roda/etc app to provide a Mudis Web Cache Server. Mudis also works naturally in Hanami because it’s a pure Ruby in-memory cache. Whether used as a singleton within a process or via IPC in cluster mode, it preserves Hanami’s lightweight and modular architecture.
