  • Facebook does not use Git due to scale issues with their large monorepo, instead opting for Mercurial.
  • Mercurial may be a better option for large monorepos, but Git has made improvements to support them better.
  • Despite some drawbacks, Git usage remains dominant with 93.87% share, due to familiarity, additional tools, and industry trends.

You and I both clone a repo with ten changes in it. We each make a new commit. Both systems will call it commit 11. If I pull your change into my repo your 11 becomes my 12.

The sequential change IDs are only consistent locally.

Got it! Are they renumbered chronologically? Like if my 11 was created before your 11, would yours be the one that's renumbered?

[-] wewbull@feddit.uk 2 points 5 months ago

No. They are not renumbered. Your 11 is always the same commit. It's consistent locally (which is what I mean by "local only") otherwise they'd change under your feet. You just can't share them with others and expect the same results. You have to use the hash for that.
