Default args and DAG parameters in Apache Airflow - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set the default start date for the DAG.

Apache Airflow

default_args = {
    'start_date': [1]
}

Drag options to blanks, or click blank then click option'

Adatetime(2023, 1, 1)

Btimedelta(days=1)

Ctimezone('UTC')

Ddatetime.now()

💡 Hint

Common Mistakes

Using timedelta instead of datetime

Using datetime.now() which is dynamic

The start_date in default_args must be a datetime object specifying when the DAG should start running.

medium

Complete the code to set the DAG's schedule interval to run daily.

Apache Airflow

dag = DAG(
    'example_dag',
    default_args=default_args,
    schedule_interval=[1]
)

Drag options to blanks, or click blank then click option'

A'@hourly'

BNone

C'@weekly'

D'@daily'

💡 Hint

Common Mistakes

Using '@hourly' or '@weekly' instead of '@daily'

Setting schedule_interval to None disables scheduling

The schedule_interval set to '@daily' makes the DAG run once every day.

3fill in blank

hard

Fix the error in setting the default retry delay to 5 minutes.

Apache Airflow

default_args = {
    'retry_delay': [1]
}

Drag options to blanks, or click blank then click option'

A5

B'5 minutes'

Ctimedelta(minutes=5)

Dtimedelta(5)

💡 Hint

Common Mistakes

Passing an integer directly

Using a string instead of timedelta

Using timedelta without specifying minutes

The retry_delay must be a timedelta object specifying the delay duration. Use timedelta(minutes=5) for 5 minutes.

4fill in blank

hard

Fill both blanks to create a DAG with default args and a weekly schedule.

Apache Airflow

dag = DAG(
    'weekly_dag',
    default_args=[1],
    schedule_interval=[2]
)

Drag options to blanks, or click blank then click option'

Adefault_args

B'@daily'

C'@weekly'

DNone

💡 Hint

Common Mistakes

Using '@daily' instead of '@weekly'

Passing None for default_args

Use the default_args dictionary for default arguments and set schedule_interval to '@weekly' for weekly runs.

5fill in blank

hard

Fill all three blanks to define default args with retries and create a DAG with a monthly schedule.

Apache Airflow

default_args = {
    'start_date': [1],
    'retries': [2],
    'retry_delay': [3]
}

dag = DAG(
    'monthly_dag',
    default_args=default_args,
    schedule_interval='@monthly'
)

Drag options to blanks, or click blank then click option'

Dtimedelta(days=1)

💡 Hint

Common Mistakes

Using strings instead of datetime or timedelta

Setting retries as string

Using timedelta without specifying minutes

Set start_date to a fixed datetime, retries to an integer count, and retry_delay to a timedelta for delay duration.
