Case Study: Experian achieves 50x faster data processing and real-time matching with Cloudera Enterprise

Experian Gets a 360 Degree Customer View

Experian Marketing Services (EMS), part of global credit and marketing leader Experian, faced a surge of multi‑structured digital data (social, web, email, transactional) that outgrew its mainframe-based systems. Clients demanded more frequent, near‑real‑time, integrated views of customers, so EMS set an ambitious goal to process over 100 million records per hour and prioritized a platform with both batch and real‑time capabilities and strong scalability.

EMS built a production Cross‑Channel Identity Resolution (CCIR) engine on Cloudera Enterprise (HBase/Hive/Pig) fed from mainframes and relational databases, running on a 35‑node cluster and holding 5 billion rows. The solution delivered a 50x performance boost, processed 500% more matches per day, was deployed in under six months, reduced infrastructure costs versus legacy systems, and provided the operational manageability and scalability needed to support rapid growth and near‑real‑time marketing.
