You can now write the hello world dag using the code below.Īirflow HelloWorld from datetime import datetimeįrom _operator import DummyOperatorįrom _operator import PythonOperatorĭag = DAG('hello_world', description='Hello World DAG', The output for the command when executed will be as below:Īirflow Admin user creation Output (airflow-venv) apples-MacBook-Air:apacheairflow bhagvan.kommadi$ airflow users create -role Admin -username admin -email admin -firstname admin -lastname admin -password admin Next, you can create the admin user using the command below:Īirflow Admin user creation airflow users create -role Admin -username admin -email admin -firstname admin -lastname admin -password admin You need to initialize the Airflow Database using the command below:Īirflow Database Setup $ source activate airflow-tutorial It uses a message queue to communicate with a different number of workers. Airflow has a modular architecture and is scalable.

They can be parameterized using python scripts. They are extensible and you can use different operators and executors. The data pipelines can be dynamic and configured in python code. A Scheduler is used for updating the task status in the metadata database. Airflow task information is stored in the database. DAG is a directed acyclic graph and is used for displaying the task relationships. The user interface helps in tracking the status of the workflow tasks.Īpache Airflow has components which are DAG, Webserver, Metadata database, and scheduler. Python is the language that you can use for creating the workflows. It has integrations that can be executed on different cloud platforms. It is open-source and part of the Apache community.
