Tabular Modeling with SQL Server 2016 Analysis Services Cookbook

By: Derek Wilson

Overview of this book

SQL Server Analysis Service (SSAS) has been widely used across multiple businesses to build smart online analytical reporting solutions. It includes two different types of modeling for analysis services: Tabular and Multi Dimensional. This book covers Tabular modeling, which uses tables and relationships with a fast in-memory engine to provide state of the art compression algorithms and query performance. The book begins by quickly taking you through the concepts required to model tabular data and set up the necessary tools and services. As you learn to create tabular models using tools such as Excel and Power View, you’ll be shown various strategies to deploy your model on the server and choose a query mode (In-memory or DirectQuery) that best suits your reporting needs. You’ll also learn how to implement key and newly introduced DAX functions to create calculated columns and measures for your model data. Last but not least, you’ll be shown techniques that will help you administer and secure your BI implementation along with some widely used tips and tricks to optimize your reporting solution. By the end of this book, you’ll have gained hands-on experience with the powerful new features that have been added to Tabular models in SSAS 2016 and you’ll be able to improve user satisfaction with faster reports and analytical queries.

Preface

Managing Analysis Services memory


SQL Server Analysis Services running in Tabular mode stores data in memory as the default behavior. In some cases, you can load more data than you have memory, which would result in failed processing. The default setting is to allow the engine to page data to disk when required. By design, the engine will begin paging to disk when the memory consumption goes higher than 60% of the total memory. When running Tabular Models, be sure to monitor the server's total memory consumption. If the system becomes stressed, you will need to reduce the amount of data being processed or add more memory.

How to do it...

  1. Connect to Tabular Services in SQL Server Management Studio.

  2. Select the localhost service, right-click and then select properties to bring up the Analysis Services Properties windows.

  3. Select the General tab and then scroll down to the Memory items.

  4. To change VertiPaq memory limit, update the Value to 70 and then click on OK.
