Lee-W opened a new issue, #65922: URL: https://github.com/apache/airflow/issues/65922
### Body ### What Extend `airflow dags backfill` for partitioned Dags so users can backfill a partition range with controlled ordering and concurrency. Basic partition backfill landed in #61464; what is missing is range flags (`--partition-start` / `--partition-end`), ordering control (in-order, parallel, pool-bounded waves), and concurrency caps independent of global parallelism. Example: deploy a new partitioned Dag and backfill 6 months of history in pool-bounded waves of 4. ### Open question Default ordering — chronological, parallel, or follow whatever the timetable suggests? How does the per-backfill concurrency cap interact with the Dag's `max_active_runs` and global parallelism? ### Related #65921 ### Committer - [x] I acknowledge that I am a maintainer/committer of the Apache Airflow project. -- This is an automated message from the Apache Git Service.
