devgonvarun opened a new issue, #62929: URL: https://github.com/apache/airflow/issues/62929
### Apache Airflow version 3.1.7 ### If "Other Airflow 3 version" selected, which one? _No response_ ### What happened? ["use_job_schedule" configuration](https://airflow.apache.org/docs/apache-airflow/stable/configurations-ref.html#use-job-schedule)) as the documentation says should "Turn off scheduler use of cron intervals by setting this to False. DAGs submitted manually in the web UI or with trigger_dag will still run.". However, setting this to "False" not only disables time based scheduling but also Assets based scheduling. ### What you think should happen instead? This configuration should only affect time based scheduling as mentioned in the documentation. Asset based scheduling should not be affected. Use Case: a Development environment with disabled time based scheduling, so that developers can develop their dags with the most freedom in this environment and when their dags are ready they can move them to higher (test and prod) environments with time based scheduling enabled. Because of "use_job_schedule" affecting both time and asset based scheduling, Asset based scheduling cannot be used in this environment. So this is a bug report on the intended behaviour of "use_job_schedule" based on the documentation OR request of a new configuration that decouples time and asset based scheduling from "use_job_schedule". ### How to reproduce Start a new airflow instance with "use_job_schedule" set to False. You can also use the "AIRFLOW__SCHEDULER__USE_JOB_SCHEDULE" environment variable to set this. Then use the following minimal Asset based scheduling dag, manually create asset trigger from the Assets menu and you will observe that the dag does not get triggered. Now retry with "use_job_schedule" set to True and the dag will get triggered. ``` from airflow.sdk import dag, task, Asset import pendulum my_asset = Asset("asset") @task def trigger_on_asset_event(): print("hello after asset event") @dag( start_date=pendulum.datetime(2025, 6, 29, tz="Europe/Berlin"), schedule=[my_asset], ) def asset_scheduled_dag(): trigger_on_asset_event() asset_scheduled_dag() ``` ### Operating System Debian GNU/Linux 12 (bookworm) ### Versions of Apache Airflow Providers _No response_ ### Deployment Official Apache Airflow Helm Chart ### Deployment details _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
