Subject changing DAG schedule_interval where depends_on_past=True
Date Fri, 08 Sep 2017 23:05:00 GMT
Hi all,

I want to move a DAG currently scheduled @daily (i.e., midnight) to be scheduled at 6 AM instead.
The DAG has a task in it that has depends_on_past=True. It seems this task won’t run anew
now because it looks 24 hours back and sees a task there hasn’t been run.

What’s the best practice for making this change? Should I change the DAG’s start_date?
Will that mess anything up?
