Just trying to be helpful by making an adequately coined term more palatable to a critical audience, thereby expediting the end of a fruitless discussion on an otherwise excellent article. Compliments.
Regarding the critique on the title: perhaps an analogy can be made to propeller cavitation on ships. Water influx rate, propeller design and operational parameters all influence the detrimental effect of water bubbles forming — deteriorating the system's efficiency.
The GPU would be the propeller, the influx is the work, and the operational parameters is what this article's about.
Well, above the fold in the chapter 'What is PlanetScale for Postgres?' the second paragraph mentions custom operator. That makes me assume it is kubernetes.
