Redis Guide

Intent

Redis should sit behind small interfaces so projects can swap clients, test with fakes, and avoid leaking Redis commands into services.

Uses

• Cache
• Distributed locks
• Rate limiting
• Idempotency key storage
• Lightweight pub/sub

Adapter Shape

RedisCache wraps a Redis-like client with get, set, and delete. More specific adapters should be added only when a project needs them.
