Ask HN: What is `PiperOrigin-RevId` in Google commits?

2 pointscidnurh1 comment

If you have a look at most Google repositories, a lot of commits in them contain this `PiperOrigin-RevId` id. I suppose that its something similar to `Change-Id` in Gerrit, but I'm not sure.

Does anyone know what's that?

"Piper" is the custom version control tooling Google uses for their central repository, so this might be a reference added when commits are exported to git repositories.

(reference for Piper being the name of the system: https://cacm.acm.org/magazines/2016/7/204032-why-google-stor... )
