Using the Tabular Object Model via Semantic Link Labs

Published 2025-08-20 by Kevin Feasel

Gilbert Quevauvilliers does a bit of connecting:

In this blog post I am going to show you how to use the powerful Semantic Link Labs library for Tabular Object Model (TOM) for semantic model manipulation.

The goal of this blog post is to give you an understanding of how to connect using TOM, then based on the documentation use one of the functions.

Don’t get me wrong the documentation is great, but when implementing it, it works a little differently and I want others to know how to use it, so it can automate and simplify some repetitive tasks.

Read on for the instructions and some of the things you can do with the Semantic Link Labs library in Microsoft Fabric.

Loading Data from Network-Protected Storage Accounts into OneLake

Published 2025-08-14 by Kevin Feasel

Matt Basile grabs some data:

AzCopy is a powerful and performant tool for copying data between Azure Storage and Microsoft OneLake, and is the preferred tool for large-scale data movement due to its ease of use and built-in performance optimizations. AzCopy now supports copying data from firewall-enabled Azure Storage accounts into OneLake using trusted workspace access. Now you can use AzCopy to load data from even network-protected storage accounts, letting you effortlessly load data into OneLake without compromising on security or performance.

Registering Applications to Read Fabric Resources

Published 2025-08-13 by Kevin Feasel

Andy Leonard works in Microsoft Entra:

My older son, Stephen, and I have been vibe coding information-dense solutions for Fabric lately. The latest application is Fabric Navigator, which simplifies navigation between Fabric Data Factory pipelines and notebooks. While Fabric Navigator includes links to instructions about configuring Azure and Fabric security to allow read access to Fabric Data Factory pipelines and notebooks, I feel a walk-through of a minimally-viable security configuration is in order. Hence, this post.

Click through to see what setting you need to make in Entra, as well as settings you need to change in Microsoft Fabric, for this to work.

Equalizing Proxy vs Redirect Rates for OneLake Access

Published 2025-08-13 by Kevin Feasel

Elizabeth Oldag announces a pricing change:

We’re thrilled to share a major update and simplification to OneLake’s capacity utilization model that will make it even easier to manage Fabric capacity and scale your data workloads. We are reducing the consumption rate of OneLake transactions via proxy to match the rate for transactions via redirect. This means you no longer have to worry where you are accessing your OneLake data from (via proxy or redirect), they will consume your capacity at the same low rate.

Read on to see what this means in practice.

Customer-Managed Keys in Microsoft Fabric Workspaces

Published 2025-08-12 by Kevin Feasel

Sumiran Tandon makes an announcement:

We’re excited to share that customer-managed keys (CMK) for Microsoft Fabric workspaces are now available in public preview in all public regions! This expansion makes it easier for customers worldwide to meet compliance requirements and implement robust data protection strategies.

Note: This feature was released in public preview in a limited set of regions earlier this year and here’s the step-by-step guide for setup.

I personally tend not to be a stickler about customer-managed versus Microsoft-managed keys, as your data is encrypted either way. That said, I know that there are environments in which this matters a lot.

Using a Child Pipeline Variable in a Parent Pipeline in Fabric Data Factory

Published 2025-08-05 by Kevin Feasel

Justin Bird passes back some information:

I answered a question on the Fabric community on return variables recently and thought I would expand upon it in a blog post. The question was how to use a variable derived in a child pipeline downstream in the parent pipeline. The person was specifically deriving a json object and wanted to iterate on the values in the parent pipeline.

No More TLS 1.1 in Microsoft Fabric

Published 2025-08-05 by Kevin Feasel

Nisha Sridhar makes an announcement:

We have officially ended the support for TLS 1.1 and earlier on the Fabric platform. As previously announced, starting July 31, 2025, all outbound connections from Fabric to customer data sources must use TLS 1.2 or later.

This update follows our earlier announcement in the TLS Deprecation for Fabric blog, where we outlined the rationale and timeline for this transition.

Read on to see what you might need to do to keep up to date.

Auto-Scale Billing for Spark in Microsoft Fabric now GA

Published 2025-08-01 by Kevin Feasel

Santhosh Kumar Ravindran announces a feature in general availability:

We’re thrilled to announce the general availability (GA) of Autoscale Billing for Apache Spark in Microsoft Fabric — a serverless billing model designed to offer greater flexibility, transparency, and cost efficiency for running Spark workloads at scale.

With this model now fully supported, Spark Jobs can run independently of your Fabric capacity and are billed on a pay-as-you-go basis — similar to how Spark works in Azure Synapse. This gives teams the freedom to scale compute as needed without impacting other workloads running on your shared Fabric capacity.

I’m of two minds here. On the one hand, there is value to having this as an option. On the other hand, one of the talking points for Microsoft Fabric is that you have one billing model. But because it’s an optional thing you can enable rather than something you must use, I’m fine with it.
