Well, you can also run it as parallel as you want to. Given that you are acting against 10k entries. Going further, if you *really* wanted to scale, then you would want to look at whether you need to regenerate all 10k projects from scratch every day. I would be surprised if a) A project that does have the ancestry suddenly stops having the ancestry b) A project with no new commits in the packaging branch starts including ancestry c) All 10k branches would have new commits every day. As always, the way to scale to N is to avoid doing this O(N) :).
