With this release of SQL Server 2019 community technology preview 3.2, we are announcing the public preview of Big Data Clusters for SQL Server 2019. Big Data Clusters for SQL Server enables big data analytics within SQL Server. It brings HDFS and Apache Spark™ into SQL Server for scale out compute and storage.
Big data clusters allow you to deploy scalable clusters of SQL Server, Apache Spark™, and HDFS running on Kubernetes. It provides all the tools and systems to ingest, store, and prepare data for analysis as well as to train and operationalize machine learning models. It allows you to query external data sources through data virtualization and combine and analyze your high-value relational data with high-volume big data. You will be also be able to build and deploy scalable and productive data-driven applications in big data clusters.
There’s a good bit in this release and because we’re in the 3.x range, you should be able to upgrade directly.
