didn't msft write an ~entire new file system specifically to scale git to the windows code base?

I have fuzzy memories on reading about it.

They wrote something that allowed them to virtualize Git -- can't remember the name of that. But it basically hydrated files on-demand when accessed in the filesystem.

The problem was I think something to do with like the number of git objects that it was scaling to causing crazy server load or something. I don't remember the technical details, but definitely something involving the scale of git objects.

Unfortunately even with these improvements, working in the repo was quite slow.

Changes branches took an eternity, and people resorted to a more workspaces style solution.

If you’re planning on starting a big tech company, I wouldn’t recommend the approach.

I thought Microsoft made a number of improvements to git to allow it work with all of their internal repos.
