The document discusses new features of Azure Cosmos DB, a multi-model database service. It begins with an introduction to NoSQL databases and how they originated. It then outlines three new key features of Cosmos DB: 1) serverless capabilities that allow customers to pay based on consumption, 2) built-in Jupyter notebooks for interactive querying and visualization, and 3) integration of notebooks with GitHub. The document concludes with a demo of how these features can be used together with other Azure services like Cognitive Search, Computer Vision, and Functions.
