Git is a version control system created by Linus Torvalds in 2005 and well-known among software developers to track changes in files. The system makes it easier for developers to work together on the same project by providing a fast and reliable distributed revision control system.
But Git wasn’t designed to work with repos with millions of files or hundreds of gigabytes, a problem that Microsoft has faced when trying to implement the system for some of its developer’s teams. As an example provided by Microsoft on a blog post at MSDN , the Windows code base has over 3.5 million files and is over 270 GB in size. Such a huge repo caused many performance issues when running Git commands.
For example, a “git checkout” would take up to three hours to complete and a simple “git status” would take almost 10 minutes to run.
