[GitHub] [airflow] potiuk commented on issue #27660: Callback added via dag_policy using cluster policy feature is not working

   Airflow 2.5.0 (released three days ago) has currently much better solution for those kind of approach - listeners:
   
   https://airflow.apache.org/docs/apache-airflow/stable/listeners.html
   
   They are much better way of handling the lifecycle of DAGs and Tasks, and we strongly recommend to upgrade rather than try to add callbacks via policies. This is a much more stable and robust solution that will likely get improved and optimized in the future and it should be used instead of policies for any kind of "lifecycle" global callbacks. 
   
   I will convert this one into a discussion now - in case more discussion is needed.
