Problem
Our payments platform generates a daily log containing every transaction across all merchants. The finance and BI teams need a clean merchant-level summary - total volume, transaction count, average amount - but the raw logs have duplicates, schema inconsistencies, and no restart safety. Design a batch pipeline that reliably produces this summary.
