We switched from Go to Rust in production. After the initial ramp-up time, it's really a lot more productive than Go for us, at least.

May I ask what "production" is?

the actual product environment, not development research or testing.

What area of computing you are talking about?

Real-time fraud detection as service for adtech companies. We started with Java but got tired of GC pauses, perhaps due to an inexperienced team but we were not able to tame it. Then we moved to Go and now we are in Rust.

That is a lot of language swapping. How long of a period did this happen over?

that sounds like data science. why aren't you in python?

He mentioned GC pauses being an issue. Python's GC is significantly less sophisticated than Java/Go, which were also not satisfactory enough.

> but got tired of GC pauses

Lol, were you guys making 3D simulations or something? "GC hiccups" usually only become an issue in high-performance-demanding applications.

Decisions in online ad bidding have to be done in fractions of a second, so unpredictable latency could cost a lot of money.

Some companies seem to be fine with that.

They use D, with their own GC implementation.

Ah I see. Makes sense. I wish all stacks of adtech can give high priority to performance. The current online ad landscape is an abomination.

We've been happy with Rust, as well.

Ditto! Would love some clarification.

Interesting! Can you tell what are you working on? It may help others.

Asking for the next Pirates movie? (couldn't resist)
