DICE, a UK-based startup, successfully sold out Wembley Stadium in under 60 seconds by leveraging MongoDB's scalability and performance capabilities. With the help of MongoDB, DICE built an application that could handle thousands of operations per second, ensuring a seamless user experience even during peak activity. The company implemented various features such as managed object pooling to ensure unique ticket allocation for each customer, location-aware sharding to distribute data to local servers near customers, and ACID-compliant operations to maintain database integrity. By selecting MongoDB as its database solution, DICE was able to scale its application to meet the demands of a rapidly growing business, while maintaining a robust plan for potential investors and expanding into new markets.
