Many plants and trees spread rotating ”helicopter seeds”. Many vines roto-grow themselves around vertical supports. Day flowers rotate to follow the sun.
Apples and oranges fall on the ground and can roll far and wide. Walnuts too.
Partial rotation is still rotation, of course: see animal joints in walk, trot and gallop.
And then there’s the belly-up pig drunk on brewery grain rolling down the hill. That mash packs a wallop!
Those rotating things still produce their thrust by pushing a wing-shaped structure through air, producing a high-pressure zone on one side, and a low-pressure zone on another. That is what I was getting at. It is the same principle.
The modern way is to sidestep the issue altogether and use Kubernetes with a database designed to run on Kubernetes. You can get sharding, replication and leader election essentially for free - you can concentrate on using the database instead of running the database.
Compute is really cheap compared to engineering man-hours.
It would be a lot cheaper to do as the slavic shamans do: collect amanita muscaria caps, dry them by your campfire to denature the poisons, and … well, you can figure out the rest.
