Subject too many long running tasks in sensors
Date Wed, 18 Oct 2017 12:58:30 GMT

We are using sensors for lightweight but taking long time tasks. It's like monitoring results
of some testing executed on remote machine. We would like to see such a task in a DAG but
with so much tasks/dags in running state we will hit max number of processes/dag runs (defined
in airflow.cfg) soon. Is it possible to have a sensor, which instead of sleep and keep the
process would just exit and be rescheduled later? Are we using sensors in wrong manner?
