I lean toward making this part of the Stream API, just like
parallelismHint(). In both cases it is about requesting cluster resources,
(I.e. Threads/CPU/Memory).
I'm strongly against (though open to new ideas) of making this a
topology-level API as proposed earlier. That approach involves a lot of "magic
strings" and feels to me like a violation of the Trident API. If there's a
better way to do it, I'm open to it, but let's not use strings as identifiers.
