SQL and .NET has been a favorite language for developers and DBAs for decades. However over the last couple of years, data processing is increasingly moving towards Big Data processing and is posing some new demands on not just scalability but also the ability to query late-structured data with custom algorithms. The new Azure Data Lake Analytics is introducing a new SQL-based language called U-SQL that combines the familiarity of SQL with new extensions for Big Data processing and easier user-extensibility. This session shows how to build big data solutions with U-SQL. You will learn how to integrate C# and .NET code to extend the power of U-SQL with C# Expressions.
