Microsoft has announced the availability of Microsoft SQL server 2019. This preview has been build on previous versions which gives you a choice of developmental languages and Operating Systems. The new DB Server comes with features like enable the query of other databases like Oracle, Teradata, and MongoDB directly from SQL Server. You will see a lot of new features in this version.

New Features SQL Server 2019

Big Data Clusters

The latest version simplifies big data analytics for SQL Server users. The new SQL server combines HDFS (the Hadoop Distributed Filing System) and Apache Spark and provides one integrated system. It provides the facility of data virtualization by integrating data without extracting, transforming and loading it. Big data clusters are difficult to deploy but if you have Kubernetes infrastructure, a single command will deploy your big data cluster in about half an hour.

Master Data Services (MDS)

The Silverlight support of Master Data Services is no longer required. HTML controls will now perform the same functionality.

Security

Advanced security support has been provided in the new version. It encrypts the data using secure enclaves technology. Similarly, support for security certificates has also been provided and the only user with the administrative role can alter the database.

Managed instances and hyper-scale storage

A new cloud-based architecture has been introduced called SQL Database Hyperscale. It provides about 100 TB of data storage. You can scale up and down your database. There are primary as well as secondary instances which perform the function accordingly and reduce the workload like in case of log service the primary instance writes the log to the log service and secondary instance consume the log service.

Oracle, Teradata, MongoDB

The PolyBase product which was in the earlier version too has been expanded. SQL Server can now support queries from external sources like Oracle, Teradata, MongoDB which as a result increases the flexibility of the SQL server

Azure Data Studio for SQL Server

Azure data studio allows you to quickly visualize your data based on its built-in features. It is a modern development environment which helps you with data development and integration tasks.

SSMS 18.0

SQL Server Management Studio has also recently been released which provide support for SQL server 2019. It has been ported to Visual Studio 2017 isolated shell. Some bug fixes like backup, restore, attach has been introduced while some features have been deprecated like Database Diagram, TSQL Debugger, OSQL.exe, Dreplay Admin UI, Configuration Manager tools, SQL Server Configuration, and Reporting Server Configuration Manager

Limitations

Functional Limitation

The additional security brings some limitation s with it. You cannot perform any mathematical operation on the encrypted data. The query will only be accepted if it has equality values like “where 1=1”.

Cost Competitive Migration

With some additional features come a huge cost. Deploying existing workloads on a new one is not an easy task. A practical solution for cost-competitive migration needs to be provided for migration from the old version to the new one.

Composite Partitioning

SQL Server still does not have support for composite partitioning which combines basic data distribution methods like range to or range to hash partitioning.

System Requirements

.NET Framework 4.6 or higher is required for this version of SQL Server.A minimum of 6 GB hard disk space is required but it will vary according to the components of SQL server you install. Minimum 1 GB memory is required but 4 GB memory is recommended for better performanceSQL Server supports 64-bit processors. It no longer supports 32-bit processors.
