> Eden is fast. Crazy fast, in fact, if you look at the size of the monorepo.

You’re measuring the wrong thing. The user actions are slow and take several seconds to complete usually. No one gives a shit how big the repo is. They care how long their operation takes.

There isn't a tool that can do this job faster. git takes a few seconds once you're at half a million commits. Facebook has many repos checked in in their entirety that are bigger than that.

That’s like saying cargo ships are fast because they carry lots of stuff. It’s still slow in absolute terms to get my stuff from China.

Compared to what? Not having a monorepo? Sure, but you run into different issues with that approach. Eden is the best solution there is for a monorepo of this size.

Yeah compared to not having a monorepo and buying more SSDs. The separate repos are much nicer to work in, but harder for the infra folks to manage. I miss having dataswarm as a separate repo. I will miss IG’s.

I understand the tradeoff. That doesn’t mean it’s “fast”. It’s slow but the other alternatives are slower.
