Rediss

Rediss is a simple Redis clone, written completely in Go.

Features

• TCP server, supports multiple concurrent clients.
• RESP protocol for client-server communication.
• AOF persistence using RESP.
• Publish/Subscribe (it exists, but has issues with multiple clients, which kind of defeats the purpose).
• Client CLI built with Cobra to communicate with the server.
• Server CLI built with Cobra to handle the database, AOF, and requests from clients.
• Makefile to handle building, as well as the dev servers.
• Completed commands for GET, SET, HGET, HSET, HGETALL, PING, and DEL, as well as unfinished implementations of PUBLISH, SUBSCRIBE, and COMMAND.
• Support for subcommands, as shown in COMMAND.
• Custom error handling.
