Re: [DISCUSS] Mechanism of SLA

[Collin McNulty]

I want to concur with Daniel and Damian, that the key behavior for SLA
should be based on when a DAG or task _should_ have run, not when it
actually started. I think that’s important from a semantic standpoint, but
also I think it’s just an important behavior to have in Airflow, because
that’s how organizations’ requirements are often stated (e.g. this report
ready by 7 AM).
