A Use for Secondary XML Indexes

Published 2026-07-01 by Kevin Feasel

Hugo Kornelis follows up from an earlier post:

Welcome back to my plansplaining blog series, where I dive deep into the details of non-obvious execution plans. This part is also a sort of follow up on my post from two weeks ago, when I wrote about the structure and usage of XML indexes, and had to admit that I had not been able to come up with good use cases for all types of secondary XML index.

That very same day, I received an email from Mikael (Micke) Eriksson, who pointed me to this question and answer on Stack Exchange for Database Administrators. I then modified that example a bit, to come up with an execution plan that I consider interesting enough that I want to describe it here.

Click through for the example and a dive into what the plan does.

Fabric Warehouse CU Metering and Workloads

Published 2026-07-01 by Kevin Feasel

Nikola Ilic digs into the numbers:

If you are using Microsoft Fabric, you’ve probably received the same email notification as me:)

I’m talking about the one about Fabric Data Warehouse and SQL analytics endpoint metering.

Starting in August 2026, Warehouse CU consumption is moving away from the current per-query CPU-time model and toward a per-workspace, virtual-node time model.

Read on to see what will change and how that should affect the way you think about this infrastructure.

The Basics of Query Folding with Power BI

Published 2026-07-01 by Kevin Feasel

Andy Brownsword explains one performance improvement technique for Power BI data transformations:

As a database developer, when I started using Power BI, I was concerned about it retrieving reams of data only to perform transformations downstream. The Power Query editor misleads us into thinking the retrieval and transformations are applied sequentially.

Thanks to Query Folding, that’s not usually the case. And that gives us more power to extract performance from the database.

This only works in situations where there’s something downstream to perform that processing, like a relational database. And one of the areas where you can affect performance, either positively or negatively, is in organizing operations such that you have a stretch of foldable operations. That way, all of it can run as one operation in the database.
