Querying Semistructured Data in Azure Data Lake with USQL
Cloud Application Development & Deployment
Data is exploding across enterprises. Much of it is semi-structured junk. Or is it junk? What are you going to do with it until you can find out? Microsoft’s Azure Data Lake is a cloud storage and analytical service for parking a variety of data. You can query that semi-structured data using an ANSI SQL language called U-SQL. In this session I will demonstrate the similarities and differences between U-SQL and T-SQL. I will demonstrate how easy it is to build a query against 21 GB of CSV files. Such queries can help you determine whether you have a gold mine in your data or a bunch of garbage before investing in a full data warehouse build.
