Modules usage
~~~~~~~~~~~~~

Airflow
^^^^^^^

**Use case:** When having a new scheduled task file on Airflow.

**Functional:**

Auto naming DAG ID and alerting failed DAG to Telegram:

- Sample code of base config Airflow ``dag`` file:

.. code-block:: python

    from airflow import DAG
    from airflow.decorators import task
    from sop_deutils.y4a_airflow import auto_dag_id, telegram_alert

    default_args = {
        "retries":  20,			# number times to retry when the task is failed
        "retry_delay": timedelta(minutes=7),			# time delay among retries
        "start_date": datetime(2023, 7, 14, 0, 0, 0),			# date that the DAG start to run 
        "owner": 'duikha',			# account name of DAG owner
        "on_failure_callback": telegram_alert,			# this contains function to alert to Telegram when the DAG/task is failed
        "execution_timeout": timedelta(hours=4),			# limit time the DAG run
    }

    dag = DAG(
        dag_id=auto_dag_id(),			# this contains function to name the DAG based on the file directory
        description='Sample DAG',			# description about the DAG
        schedule_interval="1 6 * * *",              # schedule for the DAG run
        default_args=default_args,			# default arguments contains dictionary of predefined params above
        catchup=False,			# If True, the DAG will backfill tasks from the start_date to current date
    )

    with dag:
        @task(owner='linhvu')       # account name of task owner. if not specified, the owner is the same as the DAG owner
        def function_1():
            ...

        @task(owner='trieuna')      # account name of task owner. if not specified, the owner is the same as the DAG owner
        def function_2():
            ...

        function_1() >> function_2()

-  List of account name can be found `here <https://docs.google.com/document/d/1jMouKkrJsqcGlxkgB1aJldGI-Osr3PYt3K1bwUM3I5c/edit?usp=sharing>`__.
