GitHub user kaminagakur4 added a comment to the discussion: Manually Triggering a Paused DAG
@raphaelauv is right that the scheduler will not touch a paused DAG, and right that no config changes it. Those filters are hardcoded with no conf lookup: in 3.1.3, `dagrun.py:618` has `DagModel.is_paused == false()` and `scheduler_job_runner.py:400` has `~DM.is_paused`. But there is one path that runs outside the scheduler entirely: ```bash airflow dags test <dag_id> ``` I tested this on 3.1.3. With `is_paused = True` and no scheduler process running at all, both tasks executed, the DagRun finished `success`, and `airflow dags list` still showed `is_paused: True` afterwards. `DAG.test()` creates the run and executes the tasks inside the CLI process, and there is no `is_paused` check anywhere in that path. Two caveats before you lean on it. This is not a documented guarantee. The command is supported as a debugging tool, and the 3.1.3 debug docs do not mention paused DAGs at all, so treat running-while-paused as behavior that could change. It also needs a shell where the dags folder and the metadata DB config both live, so on a managed service like MWAA or Composer the subcommand may not be exposed to you. Two other things worth knowing either way. `airflow dags trigger` on a paused DAG is not a no-op: it creates the run, the run sits in `queued`, and it starts the moment you unpause. And backfill does not get around the pause in Airflow 3. It has been scheduler driven since AIP-78, so it goes through the same query above. That is a change from 2.x. If the reason for pausing is only to stop it running on a schedule, then pause is the wrong lever. `schedule=None` on an unpaused DAG gives you manual-only triggering without keeping a duplicate DAG around. One last note if you use the UI: when a DAG is paused the trigger dialog shows "Unpause on trigger" and that box is checked by default, so triggering from the UI unpauses unless you uncheck it.
