Significant Changes

DeltaTriggerTimetable for trigger-based scheduling (#47074)

This change introduces DeltaTriggerTimetable, a new built-in timetable that complements the existing suite of Airflow timetables by supporting delta-based trigger schedules without relying on data intervals.

Airflow currently has two major types of timetables:

• Data interval-based (e.g., CronDataIntervalTimetable, DeltaDataIntervalTimetable)
• Trigger-based (e.g., CronTriggerTimetable)

However, there was no equivalent trigger-based option for delta intervals like timedelta(days=1). As a result, even simple schedules like schedule=timedelta(days=1) were interpreted through a data interval lens—adding unnecessary complexity for users who don't care about upstream/downstream data dependencies.

This feature is backported to Airflow 2.11.0 to help users begin transitioning before upgrading to Airflow 3.0.

• In Airflow 2.11, schedule=timedelta(...) still defaults to DeltaDataIntervalTimetable.
• A new config option [scheduler] create_delta_data_intervals (default: True) allows opting in to DeltaTriggerTimetable.
• In Airflow 3.0, this config defaults to False, meaning DeltaTriggerTimetable becomes the default for timedelta schedules.

By flipping this config in 2.11, users can preview and adopt the new scheduling behavior in advance — minimizing surprises during upgrade.

Consistent timing metrics across all backends (#39908, #43966)
