In a 2014 presentation at MongoDB World, “Big Dating at eHarmony, ” Thod Nguyen, main technology officer of eHarmony, talked about the way the business committed to some interesting technology to guide long-lasting attainability, scalability, and innovation needs — including a migration to your MongoDB data storage space solution. Their description of these journey is fairly step-by-step, and also the after provides an overview of key elements that assist produce the eHarmony providing:

  • Compatibility matching processor (CMP Application) — constructed on the top of relational database, the CMP produces about 3 billion possible matches each day, with about 25 terabytes of individual information within the whole matching system. In help, there are many than 60 million inquiries day-to-day — complex multi-attribute questions — looking across a lot more than 250 characteristics.
