Achal Soni created AIRFLOW-2279: ----------------------------------- Summary: Clearing Tasks Across DAGs Key: AIRFLOW-2279 URL: https://issues.apache.org/jira/browse/AIRFLOW-2279 Project: Apache Airflow Issue Type: Improvement Reporter: Achal Soni Attachments: cross_dag_ui_screenshot.png
At Stripe, we commonly have discrete dags that depend on each other by leveraging ExternalTaskSensors. We also find ourselves routinely wanting to not only clear tasks and their downstream tasks in a particular dag, but also their downstream tasks in their dependent dags (linked by ExternalTaskSensors). We currently have extended Airflow to handle this by modifying the webapp and cli tool to optionally clear dependent tasks across multiple dags (see attached screenshot). We want to open the floor for discussion with the larger Airflow community about the usage of ExternalTaskSensors and specifically how to handle clearing across dags. We are interested in learning more about the accepted practices in this regard, and are very open/willing to contribute in this area if there is interest! -- This message was sent by Atlassian JIRA (v7.6.3#76005)
