Microsoft Power BI Performance Best Practices

By: Bhavik Merchant

Overview of this book

This book comprehensively covers every layer of Power BI, from the report canvas to data modeling, transformations, storage, and architecture. Developers and architects working with any area of Power BI will be able to put their knowledge to work with this practical guide to design and implement at every stage of the analytics solution development process. This book is not only a unique collection of best practices and tips, but also provides you with a hands-on approach to identifying and fixing common performance issues. Complete with explanations of essential concepts and practical examples, you’ll learn about common design choices that affect performance and consume more resources and how to avoid these problems. You’ll grasp the general architectural issues and settings that broadly affect most solutions. As you progress, you’ll walk through each layer of a typical Power BI solution, learning how to ensure your designs can handle scale while not sacrificing usability. You’ll focus on the data layer and then work your way up to report design. We will also cover Power BI Premium and load testing. By the end of this Power BI book, you’ll be able to confidently maintain well-performing Power BI solutions with reduced effort and know how to use freely available tools and a systematic process to monitor and diagnose performance problems.

Optimizing interactive reports

When we use the term interactive report, we refer to the primary report implementation experience available in Power BI where authoring is performed in Power BI Desktop. These reports have dynamic visuals designed primarily for viewing on screens. The report elements can resize and react to screen dimension and resolution changes, and the authoring experience is What You See is What You Get (WYSIWYG).

The term interactive report is unofficial and used in this book for convenience and clarity. Microsoft specifically differentiates interactive reports from paginated reports by name – only the latter is a documented term. Paginated reports are based on SQL Server Reporting Services (SSRS) and use a different paradigm, which we will describe further in the final section of the chapter.

Note

From here on, we will only specifically call out paginated reports. If this distinction is not made, please assume we are referring to interactive reports...
