Bluedis

Trying to build a Redis clone for learning the internals of how Redis works and how to build a low-latency system. The reference article can be found here

High Level Architecture

Usage Instructions

1. Install the redis-cli on your machine.

# Ubuntu example
sudo apt-get install redis

# Arch Linux example
sudo pacman -S redis

2. Compile and run the program. You should receive a listening message of PORT 6379 which is also the default port of Redis. Make sure nothing else is running on that port.

go build
./bluedis

3. Run the redis-cli and type out redis commands through another terminal. The following redis commands work

• get
• set
• hget
• hset
• hgetall

Example Usage

• Example 1 (For testing SET, GET)

set name ritesh # sets the name to ritesh
get name        # returns ritesh

• Example 2 (For testing HGET, HSET, HGETALL)

hset users u1 ritesh # sets u1 as ritesh
hget users u1        # returns ritesh
hset users u2 abhi   # set u2 as abhi
hgetall users        # should return both users

• Example 3 (For testing AOF)
  Restart the Bluedis server after executing some SET commands. Then try to GET them. It ought to get back your data thereby proving persistance.

Roadmap

• Build the server
• Reading RESP
• Writing RESP
• Redis Commands
• Data Persistance with Append-Only File
