[GitHub] [airflow] tooptoop4 opened a new issue #8520: New boolean property in dag to prevent multi concurrent execution dates

tooptoop4 opened a new issue #8520:
URL: https://github.com/apache/airflow/issues/8520


   I want to be able to prevent the same Dagid running for multi exec dates at same time. For example DagA runs every hour I don't want the 3pm run to schedule tasks if the 2pm run is still running.
   
   I know max active dag runs is similar but it affects all dags, I want to be able to specify per dagid.
   
   Pools only operate at task level but I want to operate at dag level, in first come first serve basis, so I don't wan't to timeout the 2pm run after 60mins.

   Sorry for missing this issue when you first created. This has been possible for a long time with `DAG.max_active_runs`:
   
   ```python
   dag = DAG(dag_id="my_dag", max_active_runs=1)
   ```
