SQL Server 2019...

Today at Ignite, Microsoft announced the first public Community Technology Preview (CTP 2.0) of SQL Server 2019. 
For the first time, SQL Server 2019 comes with big data capabilities built-in, with Spark and Hadoop Distributed File System (HDFS) in the box—extending SQL Server beyond a traditional relational database. 
An enhanced data virtualization feature, PolyBase, enables you to query other databases like Oracle, Teradata, and Mongo DB directly from SQL Server without moving or copying the data.
As with every release of SQL Server, SQL Server 2019 continues to push the boundaries of security, availability and performance for all your data workloads with new compliance tools, higher performance on the latest hardware, and high availability on Windows, Linux and containers. Now you can take on any data project, from OLTP, BI and Data Warehousing to advanced analytics over big data.
