Introduction to PolyBase

First introduced with the Analytics Platform System (APS), PolyBase simplifies management and querying of both relational and non-relational data using T-SQL. It is now available in both Azure SQL Data Warehouse and SQL Server 2016. The major features of PolyBase include the ability to do ad-hoc queries on Hadoop data and the ability to import data from Hadoop and Azure blob storage to SQL Server for persistent storage. A major part of the presentation will be a demo on querying and creating data on HDFS (using Azure Blobs). Come see why PolyBase is the “glue” to creating federated data warehouse solutions where you can query data as it sits instead of having to move it all to one data platform.
