Michael Shire updated AIRFLOW-1223:
-----------------------------------
    Description: 
When making a change to a dag, in order to immediately load the change I have to click the "refresh" symbol in the dag list UI.

Is there a preferred way to programmatically force a dag to refresh/reload immediately?

sample use case:
A dag creates tasks and dependencies by reading a table (e.g. a list or a db table).  When additions or changes are made to this list, I'd like a command I can run to force the dag to update/refresh/reload straight away to pick up the new tasks and also appear refreshed in the webserver UI. 

The closest I can find is "airflow initdb" though I do not think that fully covers it and am unclear to the consequences or side effects of a running airflow.
