Backend Engineering #11.1 — Redis Fundamentals | In-Memory Data Store Explained

What exactly is Redis, why do backend applications use it, and where does it fit in a real-world production system? In this session, we break down Redis from scratch and build a clear understanding of its core concepts, data structures, and practical use cases. Topics covered: • What Redis is and why in-memory storage matters • Redis keys, values, and key naming conventions • Redis data structures: Strings, Hashes, Lists, Sets, and Sorted Sets • How to choose the right data structure for a requirement • TTL (Time To Live) and temporary data • Real-world use cases: caching, sessions, rate limiting, OTPs, counters, and leaderboards • Redis vs PostgreSQL vs Kafka • Where Redis fits in a production-grade backend architecture The goal is not just to learn Redis commands, but to understand why Redis exists, when to use it, and how to think about it as a backend engineer.
