SQL Server Big Data Clusters

SQL Server 2019 is out and one of the most interesting additions is SQL Server 2019 Big Data Clusters. In this episode, Kevin Feasel covers the marriage of SQL Server and Apache Spark. We discuss what Big Data Clusters are (and how it’s not a SQL Server feature or an edition of SQL Server, but a thing in itself), cover some of the architecture behind the solution, and explain how we can use them.

Episode Quotes

“I would probably start by pointing out one of the bigger use cases for big data clusters that kind of makes all the pieces fit, and that is, I need a data lake, but I don’t want to put my data in Azure or in AWS.”

“When Microsoft ported SQL Server to Linux, it made a lot of these Linux-based applications now, all of a sudden, available, or more available.”

“We have one extra pool called the compute pool. These things are our helper nodes. An end user is never going to connect to them directly. An end user isn’t going to care that they exist. They only work to make queries faster.”
