mik-laj commented on pull request #7510: [AIRFLOW-6887][WIP] Do not check the
state of fresh DAGRun
URL: https://github.com/apache/airflow/pull/7510
When I have following DAG File:
```python
from datetime import timedelta
from airflow.models import DAG
from airflow.operators.dummy_operator import DummyOperator
from airflow.utils.dates import days_ago
args = {
'owner': 'airflow',
'start_date': days_ago(3),
}
def create_dag(dag_number):
dag = DAG(
dag_id=f'perf_50_dag_dummy_tasks_{dag_number}_of_50',
default_args=args,
schedule_interval=timedelta(minutes=30),
# schedule_interval=None,
dagrun_timeout=timedelta(minutes=60),
is_paused_upon_creation=False,
)
DummyOperator(
task_id='task_1_of_5',
dag=dag
)
return dag
for i in range(1, 200):
globals()[f"dag_{i}"] = create_dag(i)
```
I ran following code
```
from airflow.jobs.scheduler_job import DagFileProcessor
processor = DagFileProcessor([], log)
processor.process_file(DAG_FILE, None, pickle_dags=False)
```
I got the following values:
**Before:**
Query count: 1800
Average time 6104.482 ms
**After:**
Query count: 1601
Average time 5541.349 ms
**Diff**
