Rust makes concurrency really easy, at least in comparison to C or C++. It has great cross-platform frameworks available, like Tokio which pgvecto.rs uses, and makes using them safe and straightforward.

C also makes concurrency very easy. So easy the uncareful regularly shoot off both feet. Too easy.

It's hard to get concurrency right in C

I wonder if having that sort of "safe concurrency" causes developers to overuse concurrency and introduce coordination costs.

Do we know that tokio's concurrency strategy is optimal for database access?

[fsociety]

Let’s assume that this is true. Then is the solution to go back to C where it is hard to get concurrency running correctly? Seems backwards thinking.

[throwawaymaths]

No, the solution is to keep the thing that's running quite well in c unless you can prove that it's better?

Starting with a claimed 20x speedup seems like proving it's better? https://modelz.ai/blog/pgvecto-rs
