eladkal opened a new issue, #29900: URL: https://github.com/apache/airflow/issues/29900
### Body There are some use cases where users want to trigger new DAG run as soon as one finished. This is a request I've seen several times with some variations (for example like this [Stackoverflow question](https://stackoverflow.com/q/75623153/14624409)) but the basic request is the same. The workaround users do to get such functionality is place `TriggerDagRunOperator` as last task of their DAG invoking the same DAG: ``` from datetime import datetime from airflow import DAG from airflow.operators.empty import EmptyOperator from airflow.operators.trigger_dagrun import TriggerDagRunOperator with DAG( dag_id="example", start_date=datetime(2023, 1, 1,), catchup=False, schedule=None, ) as dag: task = EmptyOperator(task_id="first") trigger = TriggerDagRunOperator( task_id="trigger", trigger_dag_id="example", ) task >> trigger ``` As you can see this works nicely:  My suggestion is to add first class support for this use case, so the above example will be changed to: ``` from datetime import datetime from airflow import DAG from airflow.operators.empty import EmptyOperator from airflow.operators.trigger_dagrun import TriggerDagRunOperator with DAG( dag_id="example", start_date=datetime(2023, 1, 1,), catchup=False, schedule="@continues", ) as dag: task = EmptyOperator(task_id="first") ``` I guess it won't exactly be "@continues" but more likely new [ScheduleArg](https://github.com/apache/airflow/blob/8b8552f5c4111fe0732067d7af06aa5285498a79/airflow/models/dag.py#L127) type but I show it like that just for simplification of the idea. ### Committer - [X] I acknowledge that I am a maintainer/committer of the Apache Airflow project. -- This is an automated message from the Apache Git Service.
