Mmm, I worked at google in 2012 and F1 was in active development.
I’ve never heard of Spanner internally. Maybe it was in development, but it was not in use.
Edit: went and read more. Looks like Spanner existed but didn’t have sql, so it wasn’t what it is today. And looks like I don’t remember things any more.
at least by 2013 it had some basic SQL (although much more limited subset that one usable today); if you needed more you would be using f1; IIRC I used spanner (without F1) in production around 2013
