I am having trouble understanding exactly at what level Prefect is able to parallelize tasks? I was looking at the Map/Reduce part of the docs for prefect, and saw that you could map a task over a number of inputs in parallel, but what if each of those tasks take up a lot of processing power, then things will be very slow. I want to use prefect as my workflow manager, but I am confused how things get parallelized. If I run prefect hooked up to my kubernetes cluster, do all the workflow steps happen inside of a single container in a single Pod? If I want to make tasks not just only have access to the resources of the Pod that the Prefect flow is running in, do I have to make each task kick off its own kubernetes job? Sorry for all the questions, it just isn't clear to me how to run a workflow on 50 inputs at once, or if that even makes sense (let me know if I should really just be running 50 separate workflows).
