   > This is true in theory -- but I think we also take pains to try and avoid 
"over scheduling" tasks in tokio -- for example, we purposely only have N input 
partitions (and hence N streams) per scan, even if there are 100+ files -- the 
goal is to keep all the cores busy, but not oversubscribed.
   
   What I was trying to say is that from a scheduling/yielding pov you can 
reason about each box in isolation. Whether you actually try to make 100s of 
concurrent (not parallel) tasks or not is a rabbit hole for another thread 😄
