Introduce a new `airflow partitions` command group with a `clear` action that nulls out `partition_key` and `partition_date` on one or more DagRuns. Useful when migrating off a partitioned timetable or fixing a Dag run whose partition metadata was set incorrectly. Targeting: - `--dag-id` (required) - `--run-id` for a single run, or - `--start-date` / `--end-date` to clear a `partition_date` range (the two modes are mutually exclusive) Safety: - `--dry-run` previews matching runs without writing - Prints the existing `partition_key` / `partition_date` before clearing each run, and skips runs already cleared
Augment `airflow partitions clear` with `--clear-task-instances`: in addition to nulling `partition_key` / `partition_date`, clear the matched DagRuns' task instances so finished runs go back to QUEUED and re-execute. Useful after fixing partition metadata when the runs themselves should also re-run against the corrected logic. Behavior: - Default behavior is unchanged — only partition fields are nulled. - With `--clear-task-instances`, runs whose partition fields are already None are no longer skipped (their TIs are still cleared). - `--dry-run` reports both projected actions without writing.
