[GitHub] [airflow] wanlce opened a new issue #21594: First scheduling issue after schedule interval change

wanlce opened a new issue #21594:
URL: https://github.com/apache/airflow/issues/21594


   ### Apache Airflow version
   
   main (development)
   
   ### What happened
   
   New version of the timetables issue
   
   eg:
   At first I had a scheduling time of 30 * * * * *
   After running it twice, I changed it to 32 * * * *
   The actual first run time after the change is fine, but because the data interval starts from the end of the previous interval, it has already been determined and not refreshed, so the displayed execution_date is incorrect.   This can cause problems with Cross-dag dependencies.

   Correct:

   My current solution is to add start = self._get_prev(end) below end = self._get_next(start) to reset data_interval_start.
   I'm not sure if this is appropriate
   Looking forward to new ideas
