Case Study: HealthCare.gov achieves high-performance, zero-data-loss operational data integration with MarkLogic

A Prescription for Operational Data Integration

MarkLogic provided the data platform powering HealthCare.gov during open enrollment, facing the challenge of integrating massive, heterogeneous operational datasets (eligibility, demographics, financial assistance, presence) to support millions of users with strict demands for low latency, data integrity, consistency, and government‑grade security.

By using MarkLogic’s operational data integration capabilities—ACID transactions, disaster recovery, and schema‑flexible indexing—the site achieved zero data loss and fast, reliable responses. The result: 11.7 million people served, about 5,000 complex transactions per second, 40,000–60,000 peak active users, 99.9% availability, and 99.9% of queries returning in under 0.1 seconds.
