PolyBase is Microsoft's data virtualization technology, allowing you to integrate SQL Server with external systems such as Hadoop and Azure Blob Storage. As of SQL Server 2019, PolyBase also allows you to connect to diverse systems such as Oracle, MongoDB, Cosmos DB, Teradata, Apache Spark, and even other SQL Server instances. In this talk, we will walk through the mechanics of PolyBase, showing how we can write T-SQL queries to access data from heterogeneous sources. We will investigate the Dynamic Management Views (DMVs) and other resources needed to tease out what the PolyBase engine is doing behind the scenes and where to go when things break down. Finally, we will look at several interesting use cases for PolyBase in the modern data environment.

You will learn:

  • How to connect multiple data platform technologies together with T-SQL
  • About the benefits and costs of data virtualization technologies, especially regarding performance
  • Investigate interesting use cases for PolyBase in the corporate world
