Hi All, Relative newbie here.
Is it possible (or is there a known pattern) for allowing atomic updates of DAGs? By atomic I mean, if a DAG is in progress running some version of the code, then it should continue to use it even if the DAG code is changed. The change should be used up only for new DAG runs started after the update. Eg I have a dag setup as: A ---> B ---> C Each step produces an intermediate build artifact which is used as input by the next stage. If the DAG step is currently executing "B" and I update the DAG code, I dont want the changes to be picked up until "C" completes. Does airflow controller provide any such feature or is this something that each developer handles on their own? Thanks for your time. -mandeep
