Problem

Our healthcare analytics platform pulls claims and member data from several operational databases, and the nightly full exports are both too slow for the utilization management team's same-day authorization decisions and heavy enough that the database teams will not sign off on any further load to production. Every record that lands in the analytics warehouse is regulated PHI, so member identifiers and clinical fields have to be stripped or pseudonymized before they reach the warehouse, not masked in views layered on top of it. Design a change-capture replication pipeline that keeps the warehouse current without adding load to the source systems.

Summary

Healthcare claims change constantly. The warehouse cannot fall behind.
