Re: ExternalTaskSensor offsets with monthly jobs

[Adrian Bridgett <ad...@opensignal.com>]

Thanks Jeremiah and Laura - yes, that's a spot on description. We're 
actually being a little lazy and running at the start of each month but 
ideally yes, we'd want to run at the end of the month (not sure if 
that's even _possible_ - I guess we could run on 28th and then use this 
new enhancement to delay running until the ETL has finished at the end - 
i.e. it could take days).

Interesting push approach - I was hoping to avoid that (as we add lots 
of reports (actually customer deliveries in our case) so really the 
daily ETL job should be fixed and the reporting jobs alter over time - 
with a push I'd have to edit the ETL job for every customer.

I see that PR has just been merged so I'll go and do some testing - we 
are overdue for an airflow upgrade :-)
