Research direction

Start with the linked jetstream_rerun DAG run and its logs, then trace how rerun handles the --statistics-only path and metrics tables. Confirm whether rerun deletes those tables, and verify that statistics-only can complete without losing the metrics data.

Description

Needs investigation, but based on jetstream_rerun DAG run https://workflow.telemetry.mozilla.org/dags/jetstream_rerun/grid?dag_run_id=manual__2025-10-02T16%3A18%3A05%2B00%3A00&task_id=jetstream_rerun&tab=logs this appears to be the case.
