A bunch of new features for Microsoft Fabric were announced at the Microsoft Fabric Community Conference (FabCon Vienna) recently. Here are all the new features that I found most interesting, with some released now and others coming soon:
- There is now mirroring support for Oracle and Google BigQuery (preview) in Fabric. See video and more info on BigQuery mirroring and Oracle mirroring
- Fabric is now extending Fabric data agents to support all mirrored databases (preview)
- Now in public preview is a new OneLake shortcut transformations to automatically convert JSON and Parquet files to Delta tables. More info
- OneLake security is now in full preview, and also available is a new tab in the OneLake catalog called Secure, where you can manage the security and permissions for all your data items (see video). More info
- Graph in Fabric (preview) is designed to enable organizations to visualize and query relationships that drive business outcomes. Built upon the proven architecture principles of LinkedIn’s graph technology, graph in Fabric can help you reveal connections across customers, partners, and supply chains (see video)
- Maps in Fabric (preview) can help you bring geospatial context to your agents and operations by transforming enormous volumes of location-based data into interactive, real-time visualizations that drive location-aware decisions and enhance business awareness (see video). More info
- Released the Fabric Extensibility Toolkit into preview—an evolution of the Microsoft Fabric Workload Development Kit but newly designed to help any developer bring their data apps to Fabric for their own organizations along with a simplified architecture and additional automation to drastically streamline development. Developers can now simply build their own Fabric items, and everything else like distribution, user interface, and security is taken care of for you. More info
- Introduced the preview of Fabric MCP, a developer-focused Model Context Protocol that enables AI-assisted code generation and item authoring in Microsoft Fabric. Designed for agent-powered development and automation, it streamlines how you build using Fabric’s public APIs with built-in templates and best-practice instructions. It also integrates with tools like Microsoft Visual Studio Code and GitHub Codespaces and is fully open and extensible
- Added horizontal tabs for open items, support for multiple active workspaces, and a new object explorer—all designed to make multitasking in Fabric smoother, faster, and more intuitive. More info
- General availability of an end-to-end migration experience natively built into Fabric, enabling Azure Synapse Analytics (data warehouse) customers to transition seamlessly to Microsoft Fabric. The migration experience allows you to migrate both metadata and data from Synapse Analytics and comes with an intelligent assessment, guided support, and AI-powered assistance to minimize the migration effort. More info
- You can now add, view and manage multiple lakehouses in a single unified view
- Mirrored database support for Fabric Data Agent: Enables users to directly connect mirrored database artifacts including Azure Cosmos DBs, Azure SQL, Oracle, Snowflake, Databricks, and other databases using open mirroring. Including this integration allows users to leverage Data Agent’s Natural Language to SQL (NL2SQL) capability, so users can ask questions in plain English, and receive LLM- powered insights across their data estate
- CI/CD support in Fabric Data Agent: Now supports CI/CD, ALM flow, and Git integration, enhancing management, version control, and collaboration for Data Agent artifacts. These features promote reliable, scalable, and auditable development practices by enabling systematic management of changes, dedicated workspaces for development stages, and broad data source support. Git integration tracks all modifications, supports branching for independent experimentation, and enables controlled merging, improving teamwork and allowing quick reversion if issues arise. More info
- Discover which query examples influenced the Data Agent response: When the Data Agent answers a question, it reviews the example queries you’ve provided and uses them to guide its reasoning. With the latest update, creators can view exactly which example queries were used during a run-step to help shape the agent’s response
- Download Diagnostics in Data Agent: Download a diagnostics file for any run step in the Data Agent chat canvas—giving you clear visibility into how the agent processed your question behind the scenes. The file includes details like which tools were used, how the question was interpreted, the intermediate reasoning steps, and any errors or fallback logic that occurred. More info
- MERGE Transact-SQL (Preview): This command blends INSERT, UPDATE, and DELETE operations all into a single statement based on your specified conditions between two tables, improving readability and providing a uniform standard for transformations across your ETL jobs. More info
- Anomaly detection in Real-time Intelligence (Preview): Quickly spot unusual patterns or behaviors in streaming data with no coding required. You select an Eventhouse, choose ID fields to monitor, and the system automatically tests models to recommend the best fit for your data. Detected anomalies appear directly in the interface, and you can experiment with models before publishing results to the Real-Time Hub. With instant alerts via Teams or email, this no-code tool empowers both analysts and business users to act fast on real-time insights
