A library that integrates Airflow DAGs with Marquez for automatic metadata collection.
This library is under active development at WeWork.
$ pip install marquez-airflow
To install from source run:
$ python setup.py install
To use this library, the line from airflow import DAG
needs to be replaced by from marquez_airflow import DAG
, see example below:
from marquez_airflow import DAG
from airflow.operators.dummy_operator import DummyOperator
DAG_NAME = 'my_DAG_name'
default_args = {
'marquez_location': 'github://data-dags/dag_location/',
'marquez_input_urns': ["s3://some_data", "s3://more_data"],
'marquez_output_urns': ["s3://output_data"],
'owner': ...,
'depends_on_past': False,
'start_date': ...,
}
dag = DAG(DAG_NAME, schedule_interval='*/10 * * * *',
default_args=default_args, description="yet another DAG")
run_this = DummyOperator(task_id='run_this', dag=dag)
run_this_too = DummyOperator(task_id='run_this_too', dag=dag)
run_this_too.set_upstream(run_this)
