KeyDB
KeyDB is a multi-threaded, Redis-compatible in-memory datastore. It speaks the Redis protocol, so existing clients, queues, rate limiters and caches connect to it unchanged, while serving them from several threads instead of one.
Disclosure: deploy links carry the author's Railway referral code — the author receives a usage kickback when you deploy. The template itself is free to deploy; Railway usage charges apply.
