Performance is a feature. Users expect instant responses, and Redis is the tool that makes it possible.
1The Caching Strategy
When a request comes in, check Redis first (Cache Hit). If the data isn't there (Cache Miss), fetch it from the main database, save it to Redis, and then return it to the user.
2Beyond Just Caching
Redis isn't just for caching. It's used for session management, real-time leaderboards, pub/sub messaging, and even as a primary database for high-speed use cases.
3Data Structures
Unlike a simple key-value store, Redis supports Strings, Lists, Sets, and Hashes. This flexibility allows you to model complex data efficiently in memory.
