Hey guys, I’m kinda confused between the requirements & limitations of tasks vs flows. I’ve experimented with each and aside from the fact that tasks need to be contained within flows, it seems that • tasks can call .submit on other tasks • flows don’t have a .submit but its not really important as you can always wrap a flow within a task • chaining flows (by direct invocations) often works, but can be problematic if you use task_runners (eg Ray) are there problems wrt to wrapping flows within tasks? I really like how quick prefect got me started but it seems there are many ways to achieve the same thing so any help from more experienced users would help
