[jira] [Commented] (AIRFLOW-1223) Is there a (preferred) method for programmatically forcing a dag's refresh

    [ https://issues.apache.org/jira/browse/AIRFLOW-1223?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16937588#comment-16937588 ]

-------------------------------

I don't think there is a CLI for that.

> 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 text file or a db table).  When additions or changes are made to this table, 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.
