Amundsen Databuilder is a data ingestion library, which is inspired by [Apache Gobblin](https://gobblin.apache.org/). It could be used in an orchestration framework(e.g. Apache Airflow) to build data from Amundsen. You could use the library either with an adhoc python script([example](https://github.com/lyft/amundsendatabuilder/blob/master/example/scripts/sample_data_loader.py)) or inside an Apache Airflow DAG([example](https://github.com/lyft/amundsendatabuilder/blob/master/example/dags/sample_dag.py)).
