In this tutorial, you’ll learn a DAX optimization technique using the UNION function. This tutorial will compare the performance of the UNION function versus Power Query and other techniques for combining tables. The UNION function combines two tables into a single table by combining their rows and removing any duplicate rows. The example in this
In this tutorial, you’ll learn what a data cache is and why it’s important. A data cache stores bits of data that could become valuable for future use. If you need the same pieces of information in a future measure or action, the data cache will provide the information you need. It eliminates making the
In this tutorial, we’re going to take a look at the second engine inside analysis services — the storage engine. We discussed the top-level engine, the formula engine, in a past tutorial. When users understand how both these engines work, it’s easier to optimize and improve the performance of your DAX queries. The storage engine’s
This tutorial will talk about optimizing your queries in DAX Studio. You’ll also learn how to mitigate the presence of the CallBackDataID if ever they appear in your calculations. This will help improve DAX’s performance in generating accurate data. If you recall from previous blog posts, CallBackDataID appears when the storage engine asks help from
This tutorial will discuss context transition and nested Iterators. You’ll learn the importance of these entities and how they can be a good source for optimization. If you recall, context transition happens when a row context changes into an equivalent filter context. You need to be aware of what’s happening when a context transition occurs
