Today on 24th September 2018 Microsoft announced the released of first CTP version of SQL Server vNext i.e. SQL Server 2019 CTP 2.0.
 

SQL Server 2016 & 2017 brought Machine Learning feature by adding R and Python support for Data Analytics and Scientists.

And now SQL Server 2019 has added Big Data capabilities under a unified platform by adding support for Apache Spark and HDFS, providing support for managing and querying unstructured data with structured/relational data.

Thus giving you an out-of-box end-to-end hybrid data platform with different types of workloads like OLTP, OLAP, DW/BI, Advance Analytics, Big Data and ML & AI on your data.

 
And just like the previous SQL Server 2017 the new SQL Server 2019 version will also run both on Windows & Linux.
