Sure it’s old but the stats I posted in a lower comment show that at YouTube’s scale, it makes sense to store.

Work in games is popular! For me it plays on the satisfaction of completing a project. A game that does this well I think is Satisfactory.

For what other communities to post this in, maybe !nostupidquestions@lemmy.world. But this one is pretty good

Are you suggesting they don’t store different versions? This (speculative ik) suggests they do.

I believe they store and that’s why it processes lowest res first and works up

Are you wondering if one instance can be spread across multiple machines? I don’t think that’s possible and seems unnecessary. I say that because spreading users onto more instances creates less load on the larger instances, not more. Edit: I guess you can scale instances across machines!

Nice that they can control it more, but I’d bet most companies don’t want to maintain their own instance
