It's not "just a database row," I oversimplified a bit too much perhaps, but it pretty much is very very little in the way of data. Since the following blog post, more stuff has been added to Git (2018, iirc): https://gitlab.com/gitlab-org/gitaly/blob/master/doc/delta_islands.md https://gitlab.com/gitlab-org/gitaly/blob/master/doc/delta_i... https://gitlab.com/gitlab-org/gitaly/-/issues/1519 https://gitlab.com/gitlab-org/gitaly/-/issues/1519 https://github.blog/2015-09-22-counting-objects/ https://github.blog/2015-09-22-counting-objects/ > Very early on we figured out that actually forking people’s repositories was not sustainable. For instance, there are almost 11,000 forks of Rails hosted on GitHub: if each one of them were its own copy of the repository, that would imply an incredible amount of redundant disk space, requiring several times more fileservers than the ones we have in our infrastructure.
