What is the purpose of the `mapped` argument in `Task.set_upstream`? is this just another way of applying mapping, or should we always be setting `mapped=True` if the upstream task is mapped? (we usually use `Task.map()` when mapping tasks)

Hey <@U020E11T0UW>, are the two tasks related? Do you want the upstream to finish all the mapped runs before proceeding to the downstream task?

I think the purpose of that is if you have  task A with mapped runs A1, A2, and A3. And then you have B1, B2, and B3, You can chain B1 as the downstream to A1 so B1 will run after A1 finished if `mapped=True`

Thanks Kevin! I'm not 100% sure I understand but we are testing it out right now.

The short answer I think is that you should set `mapped=True` is the upstream task is mapped.

Ok i think doing this did what we were hoping it would do!
