Under the covers of eBay's big data operation
For online auction powerhouse eBay (s ebay), big data is serious business. The company has 100 million active users globally, 300 million live listings at any time (and it archives them all), receives 2 billion page views daily, and handles 250 million search queries and 75 billion database calls a day. How does eBay make sense of all this activity? With Hadoop, of course.
