Redis: getting started

From your project, add a Redis database. Spluur provisions a private, password-protected Redis instance on its own infrastructure and gives you a connection string to use as an environment variable.

Free-tier Redis instances are capped by memory (256MB), not by request count. Once that limit is reached, the instance evicts the least-recently-used keys automatically rather than rejecting writes — fine for caches and rate limiters, worth knowing if you're storing something you can't afford to lose.
