Mastering SQL Server 2017

By: Miloš Radivojević, Dejan Sarka, William Durkin, Christian Cote, Matija Lah

Overview of this book

Microsoft SQL Server 2017 uses the power of R and Python for machine learning and containerization-based deployment on Windows and Linux. By learning how to use the features of SQL Server 2017 effectively, you can build scalable apps and easily perform data integration and transformation. You’ll start by brushing up on the features of SQL Server 2017. This Learning Path will then demonstrate how you can use Query Store, columnstore indexes, and In-Memory OLTP in your apps. You'll also learn to integrate Python code in SQL Server and graph database implementations for development and testing. Next, you'll get up to speed with designing and building SQL Server Integration Services (SSIS) data warehouse packages using SQL server data tools. Toward the concluding chapters, you’ll discover how to develop SSIS packages designed to maintain a data warehouse using the data flow and other control flow tasks. By the end of this Learning Path, you'll be equipped with the skills you need to design efficient, high-performance database applications with confidence. This Learning Path includes content from the following Packt books: SQL Server 2017 Developer's Guide by Miloš Radivojevi?, Dejan Sarka, et. al SQL Server 2017 Integration Services Cookbook by Christian Cote, Dejan Sarka, et. al

Introduction to SQL Server 2017

Clustered columnstore indexes

In the last sections of this chapter, you will learn how to manage a CCI. Besides optimizing query performance, you will also learn how to add a regular B-tree nonclustered index (NCI) to a CCI and use it instead of the primary key or unique constraints. When creating the NCCI in the previous sections, we didn't use LZ77 or archive compression. You will use it with a CCI in this section. Altogether, you will learn how to do the following:

  • Create clustered columnstore indexes
  • Use archive compression
  • Add B-tree NCI to a CCI
  • Use B-tree NCI for a constraint
  • Update data in a CCI

Compression and query performance

Let's start by dropping both indexes from the demo fact table, the NCCI and the CI,...
