dimberman opened a new issue #8078: Execute SubDAG tasks as part of parent DAG URL: https://github.com/apache/airflow/issues/8078 **Description** Currently, the SubDagOperator launches a completely different DAG and then monitors it as a separate entity. This has lead to all sorts of edge case (e.g. when workers have different executors than the scheduler). This Issue suggests that we instead merge all tasks from the subdag into the original DAG with an extra "original_dag" label. this means at the UI level we can still condense all subdag tasks into a single task, but a single scheduler will still perform all task launching. **Use case / motivation** We want SubDag tasks to act exactly the same as non-subdag tasks **Related Issues**
