eladkal commented on issue #7858: ShortCircuitOperator Ignoring Trigger Rules for Downstream Task and Skipping all Tasks URL: https://github.com/apache/airflow/issues/7858#issuecomment-615863490 When the callable of `ShortCircuitOperator` is evaluated to `False` it short-circuits the entire downstream branch. This means that all downstream tasks are set to `SKIP` immediately. This is done by calling `skip` method of `SkipMixin`. The `ShortCircuitOperator` is more for the usage of "Stop here. don't continue no matter what." The docs seems to be written by the spirit of `BranchPythonOperator` where it uses `skip_all_except` method of `SkipMixin`. It's not quite the same because it checks for dependency between tasks rather than trigger rules but at it uses a less violent approach. I'm not sure if this this is a bug in the `ShortCircuitOperator`. I for once have workflows that need the functionality exactly as it is now so I think this is more case of wrong documentation issue rather than a bug. On the other hand maybe the `ShortCircuitOperator` can be enhanced to have two modes: `hard` & `soft`. Where `hard` is the same behavior as now while `soft` will check if SKIP should cascade further.
