Building a Redis Clone from Scratch – Part 1: In-Memory KV Store with TCP

A step-by-step guide to building a Redis-like distributed key-value store from scratch using Java. Part 1 covers creating an in-memory storage system using ConcurrentHashMap, implementing a TCP server to handle GET, SET, and DELETE commands, and establishing basic networking communication. The tutorial includes practical code examples and testing instructions using Telnet, setting the foundation for future parts that will cover distributed systems concepts like Raft consensus, consistent hashing, and clustering.
