all of this yet my food still arrives cold af

kidding aside, I wonder if DD has the same problems as Uber or Lyft except with food delivery. Each new "change feed" is a specific region, county/municipality, or city. Federal, state, and local laws all handled delicately.

Ha.

The first thing I noticed and you almost got to it in your summary: at 1.2MM/2300 = 520 qps per node, this isn't a wild setup. I'm wrapping my head around how they're generating that amount of load. Seems like an easy task for any database to handle.
