How Disney built a big data platform on a startup budget

In order to “remove the excuses” for business users not loading their data into the system, they just need to point the custom-built user interface at their files. (Disney’s platform is growing at 5TB a day, and there are still many other types of data it needs to house, Jacob said.) Because they’ve built wrappers around the technology, Jacob’s team doesn’t talk about Hadoop and MongoDB to internal users, only about analytics and queries.
