Overview of this book

Microsoft SQL Server 2017 is a milestone in Microsoft's data platform timeline, as it brings in the power of R and Python for machine learning and containerization-based deployment on Windows and Linux. This book prepares you for advanced topics by starting with a quick introduction to SQL Server 2017's new features. Then, it introduces you to enhancements in the Transact-SQL language and new database engine capabilities before switching to a different technology: JSON support. You will take a look at the security enhancements and temporal tables. Furthermore, the book focuses on implementing advanced topics, including Query Store, columnstore indexes, and In-Memory OLTP. Toward the end of the book, you'll be introduced to R and how to use the R language with Transact-SQL for data exploration and analysis. You'll also learn to integrate Python code into SQL Server and graph database implementations as well as the deployment options on Linux and SQL Server in containers for development and testing. By the end of this book, you will be armed to design efficient, high-performance database applications without any hassle.

Chapter 6. Stretch Database

Stretch Database (Stretch DB) is a feature introduced in SQL Server 2016 that allows you to move data or a portion of data transparently and securely from your local database to the cloud (Microsoft Azure). All you need to do is mark the tables that you want to migrate, and the data movement is done transparently and securely. The intention of this feature is to let companies store their old or infrequently used data on the cloud. Companies need to store data locally and operate with active data only, thus reducing the cost and using their resources more effectively. This feature is great and very promising, but there are many limitations that reduce its usability.

In this chapter, we will cover the following points:

  • Stretch DB architecture
  • How to enable Stretch DB
  • How to select tables or part of tables for migration
  • Managing and troubleshooting Stretch DB
  • Under what circumstances should you use Stretch DB
