monoio VS diesel

There is also another thread-per-core implementation by ByteDance (TikTok) for Rust called Monoio with benchmarks[0] comparing it to Tokio and Glommio.

My understanding is you always need a runtime, somethings needs to drive the async flow. But there are others on the market, just not without the.. market domination... of tokio.

https://github.com/smol-rs/smol looks promising simply for being minimal

https://github.com/bytedance/monoio looks potentially easier to work with than tokio

https://github.com/DataDog/glommio is built around linux io_uring and seems somewhat promising for performance reasons.

I haven't played with any of these yet, because Tokio is unfortunately the path of least resistance. And a bit viral in how it's infected tings.

I assume Tokio itself, see e.g monoio or glommio, but also Seastar for C++.

I think monoio is also thread-per-core but also iouring https://github.com/bytedance/monoio. I don't know how you would shard certain keys into different threads, but if you can do that deterministically then there could be a significant speed up.

I believe this is also "thread-per-core".

Bytedance has their in-house monoio <https://github.com/bytedance/monoio> (supports io-uring) but it requires rust nightly.

There's another thread-per-core runtime called https://github.com/bytedance/monoio

It's worth mentioning: Under "Async Executors", for "io_uring" there is only "Glommio"

I recently found out that ByteDance has a competitor library which supposedly has better performance:

https://github.com/bytedance/monoio

https://github.com/DataDog/glommio/issues/554

I see that, I also tried with monoio, but the developer of that runtime mentioned that https://github.com/bytedance/monoio/blob/master/examples/hyper_server.rs might have soundness issues

7. Diesel

Both seem nice. However, both of them rely very heavily on prepared statements. Unfortunately, using prepared statements is a no-go when you use connection poolers like pgbouncer, or in my case AWS RDS proxy. A discussion in Diesel indicates that disel is not going to provide any support for disabling prepared stements (https://github.com/diesel-rs/diesel/discussions/3575), and a discussion on sqlx hints that disabling prepared statements is possible, but I haven't found any documentation or examples for it.

In addition we are experimenting with prebuild versions of diesel-cli that can be installed directly. We have a set of prebuilt binaries here. We are interested in feedback about how the provided binaries work on your platform.

First of all thanks for making this great tool. As it happens I currently toy around with using it for diesel-cli releases. See the WIP PR here. I think diesel-cli is a good example of a tool that depends on system libraries as it needs to link native database drivers, so this new release is welcome. Defining the dependencies seems to allow easily building things on x86_64-unknown-linux-gnu and x86_64-apple-darwin. It seems to pick up everything in the right way there.

I did look at mysql initially. Then I started checking other crates. Diesel is an Object Relation Model (ORM), I'm not yet keen on taking on the complication of learning ORM, I give this crate a pass in the meantime.

I would recommend people look at diesel from Rust for how nice it could be. https://diesel.rs/ Look at the complex queries example. So much more readable and easier to understand.

Most wanted missing features in diesel

There are two problems with using Rust for web servers:

1. The only production-ready Rust web servers require writing async request handlers. Async Rust is not fun.

2. The only good Postgres client library is async: https://crates.io/crates/sqlx

I'm trying to remedy the first problem with https://crates.io/crates/servlin .

Solving the second problem will be another project. I hope someone else does it. There is https://crates.io/crates/diesel but it has the same problem as async Rust: incomprehensible compiler errors.
