| schema:text | 0.5 each. (a) F-03 captures chargebacks with WHERE updated_at > last_run; the dispute system hard-deletes withdrawn chargebacks, which never reach the warehouse: log-based CDC, tombstones or a periodic full compare. (b) F-01 assumes events per card arrive in order, but the topic is partitioned by merchant_id: partition by card_id or resequence by event time. (c) F-02 drops settlement rows whose txn_date is before the last close: a late-data rule instead (load to the open period with an adjustment flag). en |
