Microsoft adds Database Hub
Microsoft is positioning Fabric as a multi-database wrangling hub that centralizes access to PostgreSQL, MySQL and SQL Server to simplify data engineering across hybrid environments. The Database Hub aims to reduce friction in building scalable analytics pipelines and deploying ML models across mixed database estates. (theregister.com)
Microsoft opened Database Hub in Fabric to early access on March 18, 2026, announcing the capability during FabCon and SQLCon event updates. (blog.fabric.microsoft.com)) The hub explicitly lists Azure SQL, Azure Cosmos DB, Azure Database for PostgreSQL, SQL Server enabled via Azure Arc, Azure Database for MySQL and Fabric databases as supported targets for unified management. (blog.fabric.microsoft.com)) Microsoft described Database Hub as agent-assisted and human-in-the-loop, with intelligent agents that continuously reason over estate-wide signals to surface changes, explain why they matter, and guide remediation, plus built-in Copilot-powered insights, observability and delegated governance. (blog.fabric.microsoft.com)) Fabric data agents have reached general availability, and Microsoft positioned those GA agents as the mechanism to feed live signals and semantic context into the new Database Hub. (venturebeat.com)) Microsoft said Fabric is growing at roughly 60% year-over-year and now serves more than 31,000 customers, while the SQL database in Fabric had seen over 50,000 databases created by December 2025. (tech.yahoo.com)) Alongside Database Hub, Microsoft published complementary features at FabCon including a Migration Assistant for SQL (preview) and enterprise Cosmos DB mirroring with Private Link and VNet to support migration and secure hybrid connectivity.
