I’ve said it before but I’ll say it again: I don’t publish book reviews here on my blog but I’m always happy to promote new Power BI books when they are published in return for a free copy.
Recently a friend and ex-Microsoft colleague of mine, Bhavik Merchant, published a book called “Microsoft Power BI Performance Best Practices” which I wrote the foreword for and I think (although of course I’m biased) it’s a good one. It’s about tuning all aspects of Power BI report and refresh performance, including DAX, data modelling, gateway configuration, Power Query/M and report design; it also covers the use of external tools like DAX Studio and Tabular Editor. From a purely technical point of view it gathers together a lot of useful information that is otherwise scattered across various documentation articles, blog posts, conference presentations and white papers; what I particularly liked, though, is the emphasis on methodology and how you should think about approaching performance tuning. If you’re new to Power BI this is a great resource but even experienced Power BI developers and consultants will learn something from it.
You can buy the book from Amazon UK here.
