UNION DAX Function Vs Power Query

UNION DAX Function Vs Power Query - Enterprise DNA

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

Data Cache: What It Is And How It Helps To Optimize Queries

Data Cache What It Is And How It Helps Optimize Queries - Enterprise DNA

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

Storage Engine – Its Role In Optimizing DAX Queries in Power BI

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

Optimizing Queries For A Faster DAX Performance

Optimizing Queries For A Faster DAX Performance

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

Iterators and Context Transitions In DAX Queries

Iterators and Context Transitions In DAX Queries

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
