DAX for Humans
By :
Generally, most DAX code runs within acceptable performance parameters. However, as semantic models grow in size and complexity it is possible to encounter measure calculations that grind to a halt at scale. In such cases, optimizing your DAX code becomes a necessity. While it is certainly true that optimizing your semantic model design can sometimes greatly simplify your DAX code and lead to better performing calculations, since this book is about DAX and not semantic modeling, we will be focusing on practical techniques for improving the performance of DAX calculations that do not involve semantic model changes and only focusing on how changes to your DAX code can improve performance.
Now, there are entire 800+ page books dedicated to optimizing DAX code that go into far greater detail than is possible in a single chapter. That said, it is our belief that you can learn the vast majority of what you will need in everyday situations within this chapter. Instead...
