-------------------------------
Summary: Add DagStateSensor
Key: AIRFLOW-4597
URL: https://issues.apache.org/jira/browse/AIRFLOW-4597
Project: Apache Airflow
Issue Type: Wish
Components: contrib
Affects Versions: 1.10.3
Reporter: HaloKu
Airflow offers variety of sensor to poke DAGs.
Most of them are time based or execution_date base.
I have use case where all I care about is the DAG state.
DAG has 3 states: Completed, Running, Failed (The sensor is on DAG level. not
on task level.)
For example:
DAG A, DAG B
B can run only if A is not in "Running" state.
I don't care which execution_date A has. Simply B start only if A doesn't have
active run.
