GoRedis

A lightweight, Redis-compatible in-memory key-value store built from scratch in Go. Integrates the RESP (Redis Serialization Protocol) for wire-level compatibility with standard Redis clients.

Features

• RESP protocol — speaks the same wire format as Redis, so existing Redis clients can connect out of the box
• Concurrent TCP server — handles multiple client connections using Go channels for connection lifecycle and command dispatch
• Thread-safe storage — sync.RWMutex-backed key-value store for safe concurrent reads and writes

Supported Commands

Command	Syntax	Description
SET	SET key value	Store a key-value pair
GET	GET key	Retrieve the value for a key
HELLO	HELLO value	Handshake/ping
CLIENT	CLIENT value	Client handshake/identification
