Hi,

Can you please let me know how to create a airflow job to run only once? Means will not be run second time.

Thanks

There are some preset schedule available in airflow! You can find more information under the DAG runs section of the official airflow document. The one that will denote that a DAG is to be scheduled only once would be the @once macro.

It should look something similar to this instantiation of a DAG object

from airflow.models import DAG

dag = DAG(
    dag_id='my_dag',
    schedule_interval='@once'
)

Once a dagrun has been created, it will not create anymore regardless of the state of the dagrun.
