Today we are announcing the availability of the Azure Data Lake in public preview. You can now try U-SQL in Visual Studio and run it over massive amounts of data in the store and across relational store such as Azure SQL Database. In this blog post, I will dive a bit deeper into how you can extend U-SQL queries with custom code.
