+ description: |
+ Whether to create DAG runs that span an interval or one single point
in time for cron schedules, when
+ a cron string is provided to `schedule` argument of a DAG. If True,
+ CronDataIntervalTimetable is used, which is the legacy Airflow
behavior suitable
+ for DAGs with well-defined data_interval you get contiguous intervals
from the end of the previous
+ interval up to the scheduled datetime. If False, CronTriggerTimetable
is used,
+ which is closer to the behavior of cron itself.
+
+ Notably, for CronTriggerTimetable, the logical_date is the same as the
time the DAG Run will try to
+ schedule, while for CronDataIntervalTimetable, the logical_date is the
beginning of the data interval,
+ but the DAG Run will try to schedule at the end of the data interval.
For more differences
+ between the two Timetables, see
