Azure Data Lake Analytics is a new analysis service for big data, with the focus of the service being on the logic of your applications (reaching your business goals) and not being affected by the complexity of the necessary infrastructure.

Similar to the Azure Data Lake Store, there is no limit to the size of individual records in the Azure Data Lake Analytics service.

Azure Data Lake Analytics is a build-on for Apache YARN (a subproject of Apache Hadoop) that allows the use of multiple data processing engines.

With Azure Data Lake Analytics, U-SQL (a combination of C# and SQL) is introduced as a new programming language for big data scenarios.

Azure Data Lake Analytics (and U-SQL) is fully integral in a Visual Studio edition of your choice with the Azure Data Lake Tools for Visual Studio.
