In the last chapter, you learned how to create an Azure Data Lake Analytics (ADLA) account and how to build and run simple jobs. In this chapter, you’ll build on that knowledge by writing more complex queries. Because U-SQL scripts compile into C# programs, you can use many C# features within U-SQL expressions.
- You’ll compare methods of structuring U-SQL for reuse, including creating indexed data stores in the U-SQL Catalog.
- You’ll use C# language features to replace and extend features of SQL.
- You’ll see how to reap benefits from previous jobs by reusing outputs and repeatedly reusing U-SQL scripts.
