Redis from scratch

A stripped down redis-server clone written as a hobby project. It is not intended to be used in production. No external dependencies were used for development.

Prequisites

Have Go installed.

Usage

• Clone the repo
• Run by executing

go run .

• Or build and run using

go build . && ./redis

• Connect to the server with any redis client. For example, redis-cli. The server listens on port 6379 by default.

$ redis-cli

Supported commands

• PING
• SET
• GET
• DEL
• MSET
• MGET
• HSET
• HGET
• HDEL
• EXISTS
• HEXISTS

Persistence

The encoding/gob package is used to asynchronously create a dump of the store in a binary file called dump.rdb every one second. This dump.rdb file is used to restore the data when then server is restarted in the same directory.
