> Are you running the "get_pandas_df" at the top-level of your DAG file? if
so, then yes - scheduler will try to execute it while parsing the DAG. Python
DAG file is "imported" and "executed" by the scheduler regularly. All the
processing should happen in the operator's "execute()'' methods (either
operators you use or the custom operators you write).
No, nothing is in the DAG file but the definition of the operators, as the
best practices state. The `get_pandas_df` is in a python file that is executed
by a custom BashOperator.
dags
import_blog
dag_import_blog.py
py_get_query.py
In dag_import_blog.py:
```
with DAG(blabla)
task_1 = BashOperator(task_id='t1',
bash_command='python3
/opt/airflow/dags/import/blog/py_get_query.py)
```
