Skip run if DAG is already running

Question

I have a DAG that I need to run only one instance at the same time. To solve this I am using max_active_runs=1 which works fine:

dag_args = {
    'owner': 'Owner',
    'depends_on_past': False,
    'start_date': datetime(2018, 01, 1, 12, 00),
    'email_on_failure': False
}

sched = timedelta(hours=1)
dag = DAG(job_id, default_args=dag_args, schedule_interval=sched, max_active_runs=1)

The problem is:

When DAG is going to be triggered and there's an instance running, AirFlow waits for this run to finish and then triggers the DAG again.

My question is:

Is there any way to skip this run so DAG will not run after this execution in this case?

Thanks!

This is just from checking the docs, but it looks like you only need to add another parameter:

catchup=False

catchup (bool) – Perform scheduler catchup (or only run latest)? Defaults to True
