An Introduction to MicrosoftFabricMgmt

Published 2026-02-25 by Kevin Feasel

Rob Sewell has a series of posts on MicrosoftFabricMgmt. The first post provides an introduction:

I have been introducing the Microsoft fabric-toolbox — covering the toolbox itself, FUAM, and FCA. All excellent tools. But there is one item in the toolbox that I have been personally involved in building, and it is the one I am most excited to write about.

Today I am kicking off a series of posts about MicrosoftFabricMgmt — an enterprise-grade PowerShell module that gives you comprehensive, scriptable control over the entire Microsoft Fabric REST API. It is hosted as part of the fabric-toolbox on GitHub.

The second post covers installation and authentication:

Yesterday I introduced the MicrosoftFabricMgmt module and explained what it can do. Today we are getting hands on — installing the module, sorting out dependencies, and making your first connection to Microsoft Fabric.

By the end of this post you will have the module installed, be authenticated, and have your first list of Fabric workspaces in your terminal.

The third post involves not having to deal with a bunch of GUIDs:

Which workspace is 948d3445-54a5-4c2a-85e7-2c3d30933992? Which capacity? Who knows — go look it up. Multiply that by fifty items across ten workspaces and you have a frustrating afternoon ahead of you.

The PowerShell Module**MicrosoftFabricMgmt** solves some of this frustration.

Working with Recent Data in Dataflows Gen2

Published 2026-02-24 by Kevin Feasel

Penny Zhou sees recent datasets:

How much time do you spend navigating to the same data sources when building dataflows? Data preparation is an iterative process—you often return to the same sources as you refine your dataflows, add new transformations, or create similar workflows. If you find yourself repeatedly connecting to the same tables, files, or databases, the Recent data module in Dataflow Gen2 is designed for you. This feature reduces friction by providing quick access to your most frequently used data items, letting you focus on the transformation logic rather than navigation.

Spark Schema Inference in Production

Published 2026-02-23 by Kevin Feasel

Miles Cole shares some advice:

To show the impact I want to highlight a benchmark that included Fabric Spark on a single 19GB CSV input file (100M Contoso dataset, sales table) for the benchmark. While there were a number of issue with this benchmark that inadvertently make Spark appear to be slow, this is only focused on the impact of inferring schema and practical recommendations.

Read on to see a performance problem that schema inference brings up. I’d also want to mention the risk of data updates blowing up your well-laid plans as a risk. Schema inference is a double-edged sword: it can be convenient and open up new approaches to development, but can just as easily cause unexpected failures.

An Overview of the Fabric Unified Admin Monitoring Tool

Published 2026-02-23 by Kevin Feasel

Rob Sewell lays out some information:

When you are responsible for a Microsoft Fabric tenant, it will not be very long before you are facing many questions.

Questions like:

  • How is my capacity being used?
  • Which workspaces are consuming the most resources?
  • What are my users actually doing?
  • When are my peak usage times?

You can scabble around in the Admin portal and try to piece together the answers, but it is a bit like trying to navigate a city with a paper map — you can get there eventually, but it is slow and painful, and you will probably miss some things along the way.

Read on to see how FUAM can help answer these sorts of questions.

Official Support for fabric-cicd Tool

Published 2026-02-20 by Kevin Feasel

Yaron Pri Gal announces support for a library:

Today, we’re announcing that fabric‑cicd—the open‑source Python deployment library for Microsoft Fabric—is now an officially supported, Microsoft‑backed tool for CI/CD automation across Fabric workspaces.

Over the past year, fabric‑cicd has rapidly evolved through collaboration with engineering, CAT, MVPs, enterprise customers, and the community. Growing usage, strong sentiment across internal and external channels, and adoption by organizations building enterprise‑grade deployment pipelines helped solidify its value within the Fabric ecosystem.

Read on to learn what this means.

When Warehouse Beats Lakehouse

Published 2026-02-18 by Kevin Feasel

Gilbert Quevauvilliers runs a test:

After my previous blog post on the different semantic model options and at the same time working with a Fabric customer, it got me thinking which is faster and which consumes less capacity when ingesting data into Power BI either via the SQL Endpoint to a Lakehouse or a query from the Warehouse.

Below you will find the information which I found very interesting indeed.

For both the Lakehouse and Warehouse source CSV’s there was a total of 237,245,585 rows.

Click through for the numbers, and a scenario in which the warehouse loads data faster than a lakehouse.

Load Testing Microsoft Fabric Redux

Published 2026-02-18 by Kevin Feasel

Reitse Eskens goes back to the well:

For those of you who have been following this blog for a long time, you may have read the posts on Fabric where I’m comparing the F64 Trial with the F2, and other shenanigans. Because Fabric keeps evolving, and new releases keep coming that improve or change the behaviour, I felt it was only fair to give Fabric a new run for its capacities.

The idea is not to create a solution that works as quickly as possible. It’s not the goal to tune Fabric, nor to get the most excitement for your Euro. The main goal of this blog (and the session that I’m presenting on this topic), is to show you the differences, the error messages and where to look when you get lost. Because, for all its intents and purposes, error handling is still tricky, and it seems to be very hard to get rid of “Something went wrong” messages.

I appreciate Reitse’s localization of the well-known phrase “most win for your Yen.”

License Types now Workspace Types in Microsoft Fabric

Published 2026-02-17 by Kevin Feasel

Nicky van Vreonhoven notices a change in language:

Just a quick post because I noticed a change in the Fabric UI, specifically in the Workspace settings.

I am working on a demo for my Power BI Gebruikersdagen session, and wanted to switch a workspace to Fabric capacity. I noticed that the setting License type has changed, and is now called Workspace type.

Read on to see where this has changed and a few more notes from Nicky.
