Question on Task dependency

I have scenario, where i need to move on to next task even if the upstream
task is failed, as long as upstream task execution is done.

Set_upstream and set_downstream methods trigger downstream task only on
success, is there a way to implement this scenario?

Hi you could have a look at the trigger_rule on your operator -

Hope that's what you meant
