Good stuff, and I hope I didn’t come across too rude but 10k parallel is not a problem for even basic setups to manage, it’s a problem solved many different ways some out of the box some not. Maybe your question was phrased wrong. But hit into 10kk parallel, there’s an interesting metric to discuss optimization.

I’m reminded of the quasi meme “You have designed an infinitely scalable service for 10 clients “
