I have no comment on your comments. Just to make my questions clearer: SLA here means the internal service agreement on how quickly a DAG should be processed by the scheduler or a task be scheduled, in order to assess the performance. I'm not talking about the SLA email notification feature in Airflow here.
In addition, it's not making sense to use *Queues* together with *LocalExecutor* at all, if you have read the documentation (link attached in my last email). Thanks.
