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.

7 months after the first official release of Fabric Studio, I am very happy to share the I just released the next major version with a lot of new features that make working with Microsoft Fabric from VSCode better and more intuitive than ever! The release includes some new capabilities that I wanted to get into the tool since the very beginning but back then the APIs just weren’t there yet. Finally they are and I integrated them into Fabric Studio v2.0!

Optimizing Multi-Notebook Jobs in Microsoft Fabric and AWS Glue

Published 2025-07-24 by Kevin Feasel

Daniel Janik flips a switch:

Are your Azure Fabric pipelines with multiple notebooks running slower than you’d like? Are you paying for more Spark compute time than you should be? The culprit might be a simple setting that’s easy to miss. In this blog post, we’ll dive into the “For pipeline running multiple notebooks” setting in Azure Fabric and explain why enabling it can significantly improve your pipeline’s performance and reduce your costs.

Click through for this, as well as a comparison with AWS Glue and ways to perform something similar there.

Goodbye, Default Semantic Models

Published 2025-07-22 by Kevin Feasel

Pradeep Srikakolapu makes an announcement:

Microsoft Fabric is officially sunsetting Default Semantic Models. This change is part of our ongoing efforts to simplify and improve the manageability, deployment, and governance of Fabric items such as warehouse, lakehouse, SQL database, and mirrored databases.

This is definitely a good thing. The idea of a default semantic model wasn’t bad, especially early on in Microsoft Fabric’s development life. But those default models almost never had enough information to do what customers actually want, so they would sit there as a distraction.
