Questions and Feature Requests for Fabric Data Engineering VS Code Extension #75

@mouna-ouazzanichahdi123

Description

Hello,

I am working with the Microsoft Fabric Data Engineering extension in Visual Studio Code and I would like support and clarification on several technical points regarding notebook execution and monitoring:

Debugger Support for Fabric Notebooks in VS Code
When I try to initiate a debugger session, it keeps loading indefinitely. I am not sure what is the correct way to use the debugger provided on this extension. Is it currently possible to use an interactive debugger (breakpoints, step-through execution, variable inspection) when running Fabric notebooks via the extension?
If not, is debugger support planned in the product roadmap?

High-Concurrency Notebook Execution
In Microsoft Fabric (e.g., Lakehouse notebooks), we can leverage high concurrency sessions, meaning multiple notebooks can execute simultaneously while users continue editing or triggering new jobs without blocking the environment.

Can the VS Code extension run notebooks directly on a high-concurrency session ? I use the Microsoft Fabric Runtime but I don't know how to use a high-concurrency session when running my notebooks.

If not currently available, is this functionality planned, and are there any known workarounds?

Monitoring Resource Consumption and Job Performance
When running notebooks inside Fabric, we can track resource usage.

Is there any feature in the extension to view these metrics in real time or after execution?

If not, will diagnostics integration with Fabric resource monitoring be added in the future?

These capabilities are crucial for ensuring an efficient and scalable development workflow aligned with what users can already do inside the Fabric web environment. Thank you very much for your support, and I look forward to your guidance or to any documentation you can share.

Kind regards,
Mouna Ouazzani-Chahdi
