My Redis Implementation in Go

I haven't learned a new programming language in a while, and what better way to do so than with a small project? I built a simple Redis implementation from scratch in Go! 🚀

Project Overview

This project is a basic implementation of Redis in Go. It includes key features such as command parsing, data structure handling for in-memory storage, client connections, and Append-Only Files (AOF) for data persistence.

Features

• Command Parsing and Execution: Efficiently parse and execute commands sent by clients.
• Data Structures: Implementation of in-memory storage using appropriate data structures.
• Append-Only Files (AOF): Data persistence using AOF.

Learning Resources

This project was inspired and guided by the article Build Redis from Scratch. The article provides an excellent overview and step-by-step instructions for building a Redis clone from scratch.

Topics Covered

• Append-Only Files (AOF)
• Command parsing and execution
• Data structures for in-memory storage
• Handling client connections

Installation

To get started, clone the repository:

git clone https://github.com/sergi-s/my-redis.git

Navigate to the project directory:

cd my-redis

Run the project:

go run .

Usage

Once the server is running, you can interact with it using a Redis client or a simple telnet connection:

telnet localhost 6379

or

redis-cli

Note: If you are going to use redis-cli, make sure to stop any running Redis service to avoid conflicts.

Example Commands

Here are some examples of how to use the implemented Redis commands:

127.0.0.1:6379> ping
PONG

127.0.0.1:6379> hset users u1 sergi
OK

127.0.0.1:6379> hgetall users
1) "u1"
2) "sergi"

127.0.0.1:6379> hset users u2 sergi2
OK

127.0.0.1:6379> hgetall users
1) "u1"
2) "sergi"
3) "u2"
4) "sergi2"

127.0.0.1:6379> HGET users u1
"sergi"

127.0.0.1:6379> HGET users u2
"sergi2"
