Description

Description

Add the ability to filter DAGs based on their Timetable type (e.g., CronTriggerTimetable, AssetOrTimeSchedule) in both the UI and public DAG APIs.

Proposed Solution

Add a new query parameter timetable_type to the DAG listing endpoints that allows filtering DAGs based on their timetable type.

Use case/motivation

Currently, while the DAG model stores timetable information in the timetable_summary field, there is no API support to filter DAGs based on their timetable type. Users cannot easily find all DAGs that use a specific type of timetable. This functionality is crucial to fix #53041. Once this is implemented, the UI filter functionality will be built on top of this.

Research direction
Start by examining the existing DAG listing API endpoint in airflow/api connexion/endpoints/dag endpoint.py to see how current filters are implemented. Look at the DAG model's timetable summary field to understand how timetable types are stored. Then, add a new query parameter 'timetable type' to the endpoint, update the OpenAPI specification, and implement the filter logic. Finally, consider the UI changes needed in airflow/www to expose this filter. Refer to related issue #53041 for context.
