Partition-Level Backfill

Concepts: paBackfill

What They Want to Hear 'I backfill at the partition level. Each partition is an independent unit of work: I can re-run it without affecting other partitions. In Airflow, I use the catchup feature or a dedicated backfill DAG with a configurable date range. I run backfills with lower priority than production tasks and validate each partition before moving to the next.' This is the answer that shows you have done this operationally, not theoretically.
