 Users could either load the data with [a python script](https://github.com/lyft/amundsendatabuilder/blob/master/example/scripts/sample_data_loader.py) with the library
 or with an [Airflow DAG](https://github.com/lyft/amundsendatabuilder/blob/master/example/dags/sample_dag.py) importing the library.
