Pedis

A sleek, Golang-powered learning adventure inspired by Redis

What is Pedis?

Pedis is a Redis clone written in Golang. It is a learning project for me to learn Redis protocol. It is not intended to be a production-ready Redis clone.

Build

Pedis does not have any external dependencies. To build it, simply run:

$ go build -o pedis-server && ./pedis-server

Usage

• Initialize a Pedis server

package main

import (
	"ahmedash95/pedis/pedis"
	"fmt"
)

func main() {
	fmt.Println("Listening on port 6379")

	config := &pedis.Config{
		EnableAof: true,
	} // to enable AOF persistence or set config to nil

	server := pedis.NewServer(config)
	server.ListenAndServe("0.0.0.0:6379")
}

• Connect to the server using a Redis client

$ redis-cli -p 6379

Supported Commands

• GET
• SET
• DEL
• EXISTS
• EXPIRE
• TTL
• HSET
• HGET
• HGETALL
• HDEL
• HLEN
• HKEYS
• HVALS

Persistence

At the moment, Pedis supports AOF persistence. It is disable by default. To enabled it, set EnableAof to true in the config. the policy for now is to append to the AOF file every second.

Benchmarks

With no disk persistence

go run main.go

$ redis-benchmark -p 6379 -n 100000 -c 100 -t set,get

SET: 411761.19 requests per second
GET: 476640.00 requests per second
