The Go maintainers found out about this after Discord switched, and realized it was actually an edge case with the GC and fixed this very shortly after. This happened back in 2016. Also, to be fair, whenever you write something the second time, you know what to expect and tend to do it better.

also note that, discord switched from Cassandra to ScyllaDB and it was a big performance gain.

I'm a programmer. I always enjoyed how some giant online services were forced to create clever solutions in order to fix issues like this, and some times even creating new technical forms of iteration, to increase efficiency.
From games to Streaming services and even food apps are responsible for some of the best languages and web services we have today. And some of them were created by a single developer.

When I worked for Expedia, a big part of our job was watching the pattern of Java garbage collection spikes in recent releases. Stuff that worked great in test environments would sometimes still have to be rolled back when it hit high volume production, only because the garbage collection pattern became too unstable.

If Discord keeps growing, they will need to write it in assembler to be fast enough..

Im an ios developer. I tried Rust last summer for one of our lambda service. It was a pleasant to work with

[GorillaRezin]

I’m using rust for the first time coming from a JavaScript background. 😅 using it for a tts reader. It’s working great.

Excellent video. Do you have a longer format of the same video. I would like to know more about this.

If I remember correctly, it was a few years ago and since then, golang has significantly improved its garbage collector. Maybe they won't face this issue anymore with golang soon after some language updates

Rust solves a problem that only a tiny fraction of real world sites have while introducing the complexity of memory management. Adopting Rust as your startup language is a case of premature optimisation at the cost of a more rapid development.

after rust performance went down by micro seconds, not milli

Discord is switching everyday, from mongo to cassandra to scylla, and now from go to rust. what else 🤣

[olegmakarikhin]

On the contrary, we are currently rewriting some mechanisms for removing an unused resource from instant deletion to delayed deletion, because instant one can provoke a squall of spinlocks.

For your next project, consider "wordpress". Don't you think choice depends on the need? Not everyone is making Discord.

[ycombine]

Yes, for your next highly available massive realtime data project with tens of millions of users use rust... For everything else though... GC is probably fine. Use go... Or whatever other language helps you ship faster.

[LadislavJech]

You can use in Java GraalVM native-image to prevent GC at all.

[ElonMuskTheOne]

meanwhile, just yesterday I tried just to login to their app, and gave up due to latency.

[albertdadzie]

Very soon we will start using assembly for backend development just to spite the frontend developers 😂

[rafatomczyk]

You forgot to add you should reserve 1 year rust learning bootcamp for devs starting new project.
