Support for Marimo Notebooks

Summary:

Please add support for running Marimo notebooks in Microsoft Fabric. Marimo is a new reactive Python notebook framework that enables fully reproducible, Git-friendly, and app-like data workflows.

Why it matters:

Fabric notebooks are great for Spark workloads but limited for lightweight, interactive data apps. Marimo would let users:

• Build reactive notebooks that update dynamically
• Run small workloads without a Spark cluster
• Version control notebooks as plain .py files
• Deploy notebooks as interactive web apps (WASM or server mode)

Requested capability:

• Allow installing and running the marimo package in Fabric notebooks or Lakehouses
• (Future) Add a “Marimo Notebook” item type or integration similar to existing notebooks

Impact:

Adds a modern, flexible notebook experience in Fabric — bridging traditional notebooks and lightweight web apps, and encouraging open-source integration.
