Andy Grove commented on ARROW-8774:
-----------------------------------

I think it would be good to add tot he design doc. I expect we'll end up
creating more JIRAs as an outcome of the discussions there.

> DataFusion currently spawns one thread per partition and this results in poor 
> performance if there are more partitions than available cores/threads. It 
> would be better to have a thread-pool that defaults to number of available 
> cores.
> Here is a Google doc where we can collaborate on a design discussion.
