Go Redis Server

A minimal Redis-compatible server implementation in Go, built from scratch with only one external dependency (tidwall/resp) for RESP serialization. This project was created to deepen my understanding of networking, concurrency, and in-memory data storage.

Features

• Redis Protocol Support: Implements the RESP (REdis Serialization Protocol) using the tidwall/resp library.
• Basic Command Support: Supports a subset of Redis commands, including:
  • GET: Retrieve the value of a key.
  • SET: Set the value of a key.
  • CLIENT: Client connection management.
  • HELLO: Handshake with the server.
• Concurrency Handling: Utilizes Go's goroutines and channels to handle multiple client connections efficiently.
• Tested with Redis Client: Verified compatibility with the official Redis CLI.

Getting Started

Prerequisites

• Go 1.20 or higher(recommended)
• Basic understanding of Redis and its commands

Installation

1. Clone the repository:

   git clone https://github.com/KDT2006/go-redis.git
   cd go-redis

2. Build the server:

   go build -o goredis
   

3. Run the server:

   ./goredis
   

Why This Project?

This project was built to:

• Learn Go Concurrency: Deepen my understanding of Go's concurrency model, including goroutines and channels, by handling multiple client connections efficiently.
• Understand Redis Internals: Gain hands-on experience with how Redis works under the hood, including its protocol (RESP) and in-memory data storage.
• Explore Networking: Learn about TCP servers, client-server communication, and protocol implementation in a real-world context.
• Showcase Problem-Solving Skills: Demonstrate my ability to build a functional, minimalistic system from scratch with minimal dependencies.

Future Improvements

Here are some potential enhancements for this project:

• Support More Redis Commands: Add support for additional Redis commands like DEL, EXISTS, INCR, EXPIRE.
• Benchmarking: Measure and optimize the server's performance under high load.
