Redis in Rust: Testing redis-cli + GET/SET support

And I’m back. It’s been a busy month with the [Genuary]([Genuary 2023]) series and life in general, but I’m still thinking about Redis in general 😄.

Up this time, let’s see what the official redis-cli app does when talking to our client and actually start handling some commands. Specifically, the very basic commands: SET and GET. With that, we would actually have a (very very basic) keystore up and running!

Redis in Rust: An Echo Server [Part 2]

Following up from Cloning Redis in Rust: RESP [Part 1], we can parse the protocol. So now… let’s do something with it.

The obvious(ish) next step, in my mind? Make a server. It’s all going to be over the network eventually, so it’s either here or storing data. Here it is!

Specifically, my goal is not to build the networking and data structures for this project from scratch. Where there are primitives or libraries that will do something like networking for me, I’m going to use them.

Ergo:

So, how do I write a simple server in Tokio?

Cloning Redis in Rust: RESP [Part 1]

Recently, I read through Build Your Own Redis with C/C++. C/C++ are ugly, so let’s run through it in Rust!

My goal: implement some large subset of Redis (both server and client) in Rust. For any features I implement, it should be compatible with Redis off the shelf. I should be able to use their client with my server and their server with my client and it should just work.

No idea if this is going to work out, but it sounds like an interesting problem!

First task: the REdis Serialization Protocol (RESP).
