I built a Redis-alternative distributed cache in Rust — with WAL persistence, mTLS, and Raft consensus

MnemeCache is an open-source distributed in-memory cache written from scratch in Rust. It is not a Redis wrapper or drop-in replacement — it's a ground-up rethink of how a modern cache should be built: separation of hot memory and persistence, mTLS security by default, and Raft-based HA without the complexity tax. 🐙 GitHub: github.com/mneme-labs/mneme 🐳 Docker Hub: hub.docker.com/r/mnemelabs Why not just use Redis? Redis is a single-process C daemon with 25 years of accumulated complexity. Persistence is bolted on (RDB snapshots or AOF logging). TLS is optional and cumbersome to configure in clusters. HA requires Sentinel — a separate fleet of processes with its own failure modes. MnemeCache is designed so that persistence, security, and HA are architectural defaults , not add-ons. What makes it different WAL + Keeper nodes — Core never touches disk. Writes stream over mTLS to dedicated Keeper processes that own all disk I/O and run snapshot compaction independently. Raft consensus — 3
