RDB - Redis-compatible Server in Rust

A lightweight Redis-compatible server implementation written in Rust using async/await with Tokio.

Features

• In-memory key-value store
• Support for basic Redis commands (SET, GET)
• RESP (Redis Serialization Protocol) protocol support
• Asynchronous I/O using Tokio
• Concurrent client handling
• Basic INFO and COMMAND support

Getting Started

Prerequisites

• Rust 1.75 or later
• Cargo (Rust's package manager)

Installation

git clone https://github.com/tennix/rdb.git
cd rdb
cargo build --release

Running the Server

cargo run

The server will start listening on 127.0.0.1:6379 (default Redis port).

Usage

You can connect to the server using any Redis client. For example, using redis-cli:

redis-cli

Supported Commands

• SET key value - Store a key-value pair
• GET key - Retrieve the value for a given key
• INFO - Get server information
• COMMAND - Get command information (minimal implementation)

Example

> INFO
> SET mykey "Hello World"
OK
> GET mykey
"Hello World"
> SAVE

Testing

Run the test suite with:

cargo test
