Redis for Caching, Queues, and Real-Time Systems

A hands-on book about using Redis beyond simple caching. It covers key design, TTLs, invalidation, counters, rate limits, queues, locks, pub/sub, streams, sessions, memory management, and production operations. Read each chapter with a small project in mind. The examples are intentionally practical: adapt them, test the failure cases, and keep notes about trade-offs.
