This week we heard the news of the release for SQL Server 2019 and a major focus of this release is data virtualization. In this episode, we discuss PolyBase--a topic we covered in Episode 95; however it has really come of age with SQL Server 2019. Our very own Kevin Feasel talks about some of the improvements of the feature and we discuss some of the use cases of when it will be useful and some of the pitfalls you might run into as you implement it. We discuss how PolyBase can help you reduce storage and other costs by avoiding the need for ETL processes that duplicate data in order to make it accessible from one source. Kevin is putting the final touches on his book PolyBase Revealed, and if you are looking for a deep dive into the subject, we invite you to check out his book.   The show notes for today's episode can be found at http://sqldatapartners.com/2019/11/06/episode-180-polybase-in-sql-server-2019. Have fun on the SQL Trail!
