URL: https://github.com/apache/airflow/issues/45274
### Apache Airflow version
Other Airflow 2 version (please specify below)
### If "Other Airflow 2 version" selected, which one?
2.10.2
### What happened?
Hi All,
Why does my DAG still behave like catchup=True and run for the missing DAG
run when I change the schedule interval? I already set it to False, but why is
it still running for the missing DAG run?
DAG code:
```python
with DAG(
dag_id=dag_id,
schedule=schedule_value,
start_date=datetime(2024, 12, 1),
catchup=False,
tags=["xxx"],
default_args=default_args,
) as dag:
schemas = variable_mapping["data"]
with TaskGroup(
group_id="compare",
tooltip="vs",
) as column_compare_tg:
for schema in list(schemas.keys()):
create_task(
env_vars, job_name=job_name, redshift_schema=schema,
_type="compare"
)
send_alert = create_task(env_vars, job_name=job_name, _type="alert")
column_compare_tg >> send_alert
```
### What you think should happen instead?
When I changed the schedule interval, the DAG should skip the missing run
and run only one task.
### How to reproduce
1. Create a DAG with `schedule_value` as a Airflow variable
2. First time: set the schedule as 2 time a day
3. Second time: set the schedule as 5 time a day
### Operating System
Debian GNU/Linux 12 (bookworm)
