# Redis Clone in Go

A lightweight, concurrent key-value store built from scratch in Go. This project implements the Redis protocol (RESP) and features custom sharding and a modular command system.

## Key Features

- **High Concurrency:** Uses data sharding to minimize lock contention.
- **RESP Protocol:** Fully compatible with standard tools like `redis-cli`.
- **Pub/Sub System:** Real-time message broadcasting for connected clients.
- **Modular Architecture:** Easy-to-extend command registry for adding new features.

## Quick Start

### 1. Run the Server

```bash
go run main.go

```

### 2. Connect with `redis-cli`

Open a new terminal window and run:

```bash
redis-cli

```

### 3. Try it out

```bash
> SET mykey "Hello Go"
OK
> GET mykey
"Hello Go"
> SUBSCRIBE news

```

## Project Structure

- `pkg/core`: Core data structures and protocol serialization.
- `pkg/commands`: The registry and logic for all commands.
- `pkg/pubsub`: Independent message hub for real-time communication.
