Problem
We publish credit ratings and financial data to thousands of institutional clients who pay for real-time feeds and historical databases. Our dbt transformation layer has become a bottleneck - full refreshes take 6 hours and we can't meet our real-time client SLAs, but incremental models are giving us stale data when a company's historical prices need retroactive adjustment after a stock split or merger. Design a transformation pipeline that handles both real-time feed delivery and retroactive historical corrections.
