Google uses some variant of perforce, just like MS has been doing.

  They used to, but now they use Piper which is built on top of mercurial.

    Piper is not built on top of Mercurial.

      Sorry, you are right, I got it confused with some other work Google was doing to improve the scalability of mercurial. It's not based on perforce though either, appears to be entirely custom technology.

        They first outgrew git, then outgrew perforce and implemented a custom server on top of their usual storage/database stack.
