nice, I was just deciding what to use. I tried nextcloud, but I'm running a php system on my machines.

Senior Backend (8+ yrs exp)

I'm a backend-focused software engineer with deep experience building scalable, cloud-native systems. I’ve worked with startups across Latin America, Europe, and the U.S., taking on roles that span backend development, cloud infrastructure, and DevOps. My main area of expetise within backend is database tunning / optimization.

Also, I write about databases and software development in https://charlesfonseca.substack.com.

Author here. This is part 4 of my journey learning systems programming by building a Redis clone.

Happy to answer any questions about the implementation or benchmarks!

Same. It’s good to know that other people feel the same way.

The requests were made concurrently. I don't understand your question. Passing in an array or a pointer does not matter.

Fair. The languages have to come up with something based on APIs that were not meant for that, like io_uring, etc.

What changed, why it matters, and how to use the new API.

The format was made for taking snapshots, it’s terrible for lookup.

I didn’t know that, that’s pretty cool

It’s not feasible to do that in a single threaded system. The main drawback of disk persistence is that you need a log of memory to keep the file buffer open and pointers. If the key you’re looking for is not on disk, you’ll get awful results, the rdb format will give you worst then Postgres performance. You have to use another file format to optimize for a larger cache

That’s a good point, I should had renamed it. You can’t trust these big corp

Redis dynamically allocates memory, the idea of the project is to pre allocate everything, so it’s by principle faster than Redis.
barddoo

I definitely plan to do that in the future

Agree. I used it mostly for getting ideas, the memory management for example, Gemini listed so many different ways of managing memory I didn’t even know existed. I know I wanted to pre allocate memory like tigerbeetle does, so the hybrid approach was perfect. Essentially it has 3 different allocators, a huge one for the cache, a arena allocator for context, intermediate state like pub/sub and temp one, for requests. It was 100% Gemini’s idea.
