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.

Knowledge sharing and awareness

In the previous section, we talked about the importance of being pro-active about performance management. Since there are many areas to cover, some being quite technical, we need to have the right level of complexity and relevance for the audience. We will introduce these groups in general then summarize with role-specific advice.

Helping self-service users

One of Power BI's greatest strengths is its approachability and ease of use for non-technical users or analysts who are not professional BI developers. The drawback of this is that lack of knowledge can lead to poorly optimized solutions. We recommend using the guidance in later chapters to create the following:

  • Report Design Guide – This will incorporate style, theme, and design choices to avoid. These can even be supplied as a Power BI template file (.pbit).
  • Data Modeling/Loading Guide – This will have common guidance such as the basics of dimensional modeling...
