Your own miniature redis written in Go.

MyRedis is a minimal yet functional in-memory key-value store inspired by Redis. Designed for learning and experimentation, MyRedis demonstrates the core concepts of Redis, including its protocol, data structures, and command parsing, all implemented from scratch.

• A Redis clone that lets you store and retrieve strings and hashes and delete them.
• Parse RESP (Redis Serialization Protocol) to handle commands and send responses.
• Handle multiple client connections simultaneously using goroutines.
• Persist data to disk using an Append Only File (AOF) so the server can recover after crashes or restarts.
• Accept and manage client connections with simple networking.
• Easily extendable design for adding new commands or features.

• Go (Latest)
• redis-cli (sudo apt install redis-tools)

Clone this repository:

git clone https://github.com/DSCmatter/MyRedis.git cd MyRedis cd src/

You can run the server manually or use the provided shell script.

sudo snap stop redis go run *.go // runs all files in the directory redis-cli ping // will output with PONG

By default, the server runs on 6379.

A shell script runMyRedis.sh is included to simplify running and testing:

chmod +x runMyRedis.sh ./runMyRedis.sh OR bash runMyRedis.sh

This script stops any existing Redis instance, runs MyRedis, waits briefly, then connects with redis-cli.

You can interact with MyRedis using the redis-cli tool or any compatible Redis client:

redis-cli 

Try basic commands:

set name leon get name del name 

hset names v1 ada hset names v2 leon hgetall names Response: 1) "v1" 2) "Ada" 3) "v2" 4) "leon

main.go # Initializer resp.go # RESP parser handler.go # handles basic commands  aof.go # data persistence
