> PlanetScale, with their latest Metal introduction, optimized for super low latency (they act like they've reinvented the wheel, lol), but they clearly have something in mind going in this direction.

I’ve spoken to them personally, and didn’t get the impression at all that they think they’ve “re-invented the wheel.” More like they realized that separating compute and storage was a god-awful idea, and are bringing back how things used to be in the days of boring tech.

Also, re: branching, PS MySQL definitely has that. I assume they’ll bring it to Postgres.
