This series guides you through building an in-memory database similar to Redis using Go. It focuses on low-level details involving databases, data structures, and algorithms. The project highlights include understanding RESP for command parsing, using goroutines for multiple connections, and implementing data persistence with the Append Only File (AOF) method. Suitable for developers familiar with Go and Redis commands.

Build Redis from scratch

Are these articles suitable for me, and will I be able to understand them?

I’ve used Redis as a cached middleware in an Express.js RestAPI backend to improve its performance. The result was a huge success - the server performance improved by more than 200%. The idea was to not fetch all the time from the database - using Redis we could cache the data while was not modified.

That was an interesting one. Though the article misses few screenshots and I personally don’t like use of <code>append</code> to work with arrays whose length is known, it’s worth checking out

That looks like a fun project, well paced to learn the implementation

Go is just perfect for this kind of projects!
