eBay Engages Customers with Personalized Recommendations

Industry: eCommerce

eBay is the world’s largest online marketplace, enabling the buying and selling of practically anything. Founded in 1995, eBay connects a diverse and passionate community of individual buyers and sellers, as well as small businesses. eBay’s collective impact on eCommerce is staggering: In 2012, the total value of goods sold on eBay was $75.4 billion. eBay currently serves over 112 million active users and 400+ million items for sale.

One of the keys to eBay’s extraordinary success is its ability to turn the enormous volumes of data it generates into useful insights that its customers can glean directly from the pages they frequent. To accommodate eBay’s explosive data growth—its data centers perform billions of reads and writes each day—and the increasing demand to process data at blistering speeds, eBay needed a solution that did not have the typical bottlenecks, scalability issues and transactional constraints associated with common relational database approaches. The company also needed to perform rapid analysis on a broad assortment of the structured and unstructured data it captured.
