> 10,000!!!! req/sec

I've forgotten how to count that low.

I'm gonna need a Kubernetes cluster with a distributed database with a caching layer, RabbitMQ/Kafka/whatever, and...

10,000!!!! is such a huge number I don't think we could even represent with a computer.

Being obviously pedantic here, I agree with what you meant.

Well, it depends what those requests are doing surely? I always thought it was weird to treat "request" as a unit of measurement. Are you requesting a static help page, or a GraphQL search query?
