Supercharging Spring Boot with Redis: Caching, Pub/Sub, Rate Limiting & More

From ~500ms PostgreSQL queries to ~1ms Redis hits — a complete hands-on guide. If you've ever watched your API response times crawl under load and thought "there must be a better way" — Redis is that better way. In this post, I'll walk you through a production-ready Spring Boot project I built to explore everything Redis can do: declarative caching, raw data structures, Pub/Sub messaging, rate limiting, and session management. By the end, you'll understand not just how to wire Redis into Spring Boot, but why each piece works — and what traps to avoid along the way.
