Looks to me like having the ability to write Go syntax and interop directly with C is the plus.

"To keep things simple, there are no channels, goroutines, closures, or generics."

I wonder if it could be integrated with https://github.com/tidwall/neco, which has Go-like coroutines, channels, and synchronization methods.

I do this all the time. I’ll spend weeks or months on a project, with thousands of wip commits and various fragmented branches. When ready, I’ll squash it all into a single initial commit for public consumption.

This reminds me of a card swiping video game system I made years ago.

Or this.

    func fetchUser(id int) (user User, err error) {
        resp, err := http.Get(fmt.Sprintf("https://api.example.com/users/%d", id))
        if err != nil {
            return user, err
        }
        defer resp.Body.Close()
        return user, json.NewDecoder(resp.Body).Decode(&user)
    }

A bird in the hand.

Thanks! The Pogocache sharded hashmap design is optimized for extremely low contention and good memory locality. It super rare for any two threads to ever wait on the same key. That's the biggest part and it's all in the src/pogocache.c file. But the network layer is finely tuned too.

Mostly I perfed and profiled ad nauseam, monitoring cpu cycles along the way. I found that keeping a focus on latency and cycles was primo, and the rest fell into place.

Thanks you for the blog post about TG when it came out.

The protocols are autodetected. No need to carry multiple ports around.

Yes, it is highly hand optimized. There's a description of some of the methods I used near the bottom of there README. I mainly focused on minimizing contention, with the sharded hashmap and such. But the networking layer is carefully crafted.

Not intending to make pogocache into a sql database. I prefer keeping it a cache. More so exploring ways to work with existing databases such as sqlite, duckdb, postgres. Kinda like providing proxy-ish operations that transparently cache sql reads.

That's the only way right now. The other ways I'm considering is with an environment variable and/or acl.
