Linking Fabric Warehouse SQL Query Results to the Capacity Metrics App

Published 2025-09-30 by Kevin Feasel

Chris Webb follows up on a previous post:

Following on from my post two weeks ago about how to get the details of Power BI operations seen in the Capacity Metrics App using the OperationId column on the Timepoint Detail page, I thought it was important to point out that you can do the same thing with TSQL queries against a Fabric Warehouse/SQL Endpoint and with Spark jobs. These two areas of Fabric are outside my area of expertise so please excuse any mistakes or simplifications, but I know a lot of you are Fabric capacity admins so I hope you’ll find this useful.

CONTINUE and BREAK in T-SQL WHILE Loops

Published 2025-09-30 by Kevin Feasel

Erik Darling tries to count and gets kind of far along. The key part of the video is the use of CONTINUE and BREAK as control logic in WHILE loops. CONTINUE is something I’ve very rarely used, though it’s pretty useful. BREAK, however, is something I’m quite familiar with, especially in conjunction with record counts. This way, you can perform small updates (e.g., update 1000 records) with a filter that tells you which records still need updated, and when @@ROWCOUNT is below 1000, you know you’re done with the updates.

Fabric Mirroring for Azure SQL MI Now GA

Published 2025-09-30 by Kevin Feasel

Ajay Jagannathan announces a feature has gone to general availability:

Mirroring in Fabric is a powerful feature that allows you to replicate data from various data sources such as your Azure SQL Managed Instance to Fabric’s OneLake. This ensures that your data is always up-to-date and readily available for advanced analytics, AI, and data science without the need for complex ETL processes.

Jokes about Azure SQL Managed Instance aside, it’s good that these features are becoming generally available.

Splitting GUIDs into Multiple BIGINTs for Columnstore

Published 2025-09-30 by Kevin Feasel

Forrest McDaniel performs an experiment:

You may have run into issues with GUIDs as clustering keys, but another major problem is in columnstore. Smart people at Microsoft wrote columnstore in a way to take advantage of modern CPU features, but those CPU features don’t play well with datatypes larger than 8 bytes. Which includes GUIDs.

Read on for the demonstration of this, a clever workaround, and the ramifications of splitting GUIDs into two BIGINTs. Full points for cleverness, though like Forrest, I wouldn’t want to use this in production.

Content Discovery in Microsoft Fabric

Published 2025-09-30 by Kevin Feasel

Jon Vöge wants to find data:

So you built a nice Data Platform on Microsoft Fabric. Users are happily using a few Models and Reports, but you face two problems:

  1. Users are not aware of all the other awesome models, reports and even lakehouses that they already have access to, which they should be using.
  2. Users also don’t know anything about the models, report and lakehouses that they don’t have access to, but which could also be useful for them, if they requested access.

For my take on how best to solve this natively in Fabric, read on below.

Read on to see how you can enable content discovery.

S3-Compatible Object Storage in SQL Server 2025

Published 2025-09-30 by Kevin Feasel

Anthony Nocentino updates a guide for SQL Server 2025:

In this blog post, I’ve implemented two example environments for using SQL Server’s S3 object integration. One for backup and restore to S3-compatible object storage and the other for data virtualization using PolyBase connectivity to S3-compatible object storage. This work aims to get you up and running as quickly as possible to work with these new features. I implemented this in Docker Compose since that handles all the implementation and configuration steps for you. The complete code for this is available on my GitHub repo. I’m walking you through the implementation here in this post.
