Hi, Resource label/tag has gained increasing popularity, for example, both GCP and AWS allow labels/tags to be attached to the cloud resources they offered. I am wondering whether the airflow community is interested in adding some default top-level airflow labels for all cloud resources that support labeling, spawned from airflow. In other words, all operators creating/using these resources will include the airflow labels (e.g., "airflow-version" : "1.8.1").
The benefits are twofold: - enable measuring the impact of apache airflow quantitatively at different places. - allow users to better organize airflow triggered cloud resources. These top-level labels will then be merged with user-provided labels specified in the various operators (e.g. https://github.com/apache/incubator-airflow/blob/master/airflow/contrib/operators/dataproc_operator.py#L55 ). Thanks. Feng
