Redis Patterns

Covers the bread and butter of Redis in production: cache-aside and write-through patterns, distributed locks with proper token-based release, sliding window rate limiting via Lua, and the difference between Pub/Sub (fire-and-forget) and Streams (durable queues with consumer groups). The connection pooling and key naming conventions alone will save you from common mistakes. Includes tag-based cache invalidation for grouped keys and session storage with hash structures. The atomic operations are correctly implemented with pipelines and Lua scripts where needed. This is the reference you reach for when adding Redis to an app, not learning it from scratch.
