Google calls API calls “queries”… because of their history as a search engine. QPS == API calls/per second == Requests per second
That said, I can’t imagine these numbers mean much to anyone after a certain point. It’s not like either company is running a single service handling them. The scale is limited by their budget and access to servers because my traffic shouldn’t impact yours. I feel like the better number is RPS/QPS per table or per logical database or whatever.
