Those are mind-boggling numbers. Although I kind of doubt that "almost every" engineer has access to the entire repo, especially when it comes to the search ranking stuff.
> (...) all 2 billion lines sit in a single code repository available to all 25,000 Google engineers.
I wonder how close the "piper" system is to the code.google.com project.
"The two internet giants (Google and Facebook) are working on an open source version control system that anyone can use to juggle code on a massive scale. It’s based on an existing system called Mercurial. “We’re attempting to see if we can scale Mercurial to the size of the Google repository,” Potvin says, indicating that Google is working hand-in-hand with programming guru Bryan O’Sullivan and others who help overs…
Edit: And for those that are just shocked that git isn't the answer.

Because Google and Facebook are using Mercurial over Git internally. Edit: And for those that are just shocked that git isn't the answer. Facebook: https://code.facebook.com/posts/218678814984400/scaling-merc... Google: http://www.primordia.com/blog/2010/01/23/why-google-uses-mer...

I wonder how much time it takes to clone the repo, provided they use git.
The bad news was that it allowed people to say "I've just changed the API to to support the initiative, code released after this commit will need to be updated." and have that effect hundreds of projects, but at the same time, the project teams could do the adaptation very quickly and adapt. With the orb on their desk telling them at that their integration and unit tests were passing.
I thought to myself, if there is ever a distributed world wide operating system / environment, it is going to look something like that.
This explains quite some things. Still, this is not a very forward-thinking solution. Building and combining microservices – effectively UNIX philosophy applied to the web – is the most effective way to make progress. EDIT: Seems like I misunderstood the article – from the way I read it, it sounded like Google has a monolithic codebase, with heavily dependent products, deployed monolithically. As zaphar mentioned, it…
