If you have a lot of volume and variety of data that you want to investigate and analyze, it is important to have a scalable data lake to store it and a scalable and extensible query language to process it. Microsoft introduces the Azure Data Lake Big Data Platform with U-SQL as its query engine to help you tame your big data monster. In this video, Seth and Michael are giving a demo-heavy preview of Michael's presentations on U-SQL at the Microsoft Data Science Summit.
