I have operated a BDR Postgres cluster spread across five global regions with hundreds of TB of data, with multiple reader nodes attached to each primary, each on instances with node-local NVMe drives; the entire cluster saw over 1 million QPS. I will grant you that there are much larger examples of scale, but they typically exist on DBs designed for that, like Spanner, Vitess, etc.
I am not asking for hand-holding, I’m asking for one single publicly-available example of this being done, because I cannot fathom it being necessary or beneficial, and you have not provided concrete proof.
