Problem

We're migrating our data platform to a lakehouse. Our source systems have a mix of reference data that changes over time: product catalog updates, customer profile changes, store-to-region assignments. Finance needs to be able to report historical revenue using the values that were in effect at the time of each sale. Design a data pipeline with proper CI/CD to land this data correctly.

Summary

Data lands continuously. History must survive every update.
