Microsoft Fabric Database Hub only a 'partial' solution for admins

Microsoft's new Fabric Database Hub is a "partial solution" for enterprises relying on systems outside the vendor's portfolio, but within these confines, it could make databases more connected and manageable, say analysts reacting to the news.

Operating within Microsoft's Fabric data platform, Database Hub promises a single location where engineers can manage a range of common Microsoft database services, including Azure SQL Server, multi-model system Azure Cosmos DB, Azure Database for PostgreSQL, SQL Server enabled by Azure Arc, Azure Database for MySQL, and other Fabric services. Microsoft's LLM tool, Copilot, also promises to provide insights to help teams quickly understand what's happening across their database estate and why.

DBAs can manage systems on-premises, on PaaS, and on SaaS, but they would be limited to the Microsoft databases portfolio, Shireesh Thota, Microsoft corporate vice president for databases, said in a blog post.

For Andrew Snodgrass, research vice president of Directions on Microsoft, this is an important weakness in the proposal.

"All the enterprises I know have a bunch of non-Microsoft databases products and services that this won't touch. That means it's a partial solution for managing your data estate," he told The Register.

"It will probably expand in the future but has limited appeal at the moment, unless your world is centered on Azure and SQL Server. Or more likely, that you're setting up an analytics environment in Fabric," he said.

It's a good idea, but "more of a watch and see situation." Snodgrass compared its development to that of Microsoft's data catalog Purview, which is "playing catchup compared to competitors."

"Take a look at Informatica and Collibra (and several others). They also have AI, monitor changes, deliver to analytics, and have solid governance controls. And they are mature offerings with large install bases. I think it will be difficult to pull customers away from them," Snodgrass said.

Devin Pratt, research director at IDC, said the Database Hub could become "highly valuable" for organizations already using Microsoft data services.

"The appeal is not just simpler management. It is the chance to connect operational databases, analytics, governance, and semantic context across the estate so Copilot and agents can work from a fuller picture," he told The Reg.

Pratt said the main advantage of the Database Hub is providing context within the Fabric platform, as it ties database management to lakehouse OneLake, Fabric IQ, semantic models, and data and operations agents. "That gives teams a better chance to move from signals to business context and then to action, rather than treating databases as a separate admin silo," he said.

However, organizations looking for flexibility might want to bring a number of tools to the problem and integrate them.

"The alternative is a mixed-tool approach, using native database tools alongside separate monitoring, governance, and automation layers across heterogeneous environments. That can offer more flexibility, while Microsoft's advantage is tighter integration across operational data, analytics, governance, and AI. The tradeoff is flexibility versus integration," he said.

Microsoft has released no further details about the level of automation available in the Database Hub, such as whether it extends to database tuning, which has proven challenging to automate. It has yet to respond to The Register's questions in this regard.

Last year, Carnegie Mellon University Database Group published a paper showing that vector embedding algorithms could improve the performance of default settings on common PostgreSQL database services by a factor of two to ten. Using a separate "LLM-booster," the time running the protocol could be cut from around 12 hours to around 50 minutes.

Andy Pavlo, associate professor at Carnegie Mellon University Database Group, said Microsoft had not released much detail about its approach.

"The demo video shows an example for SQL Server where there is a long-running transaction that the agent identifies as causing problems. They then have a model provide a human-readable explanation and the action to remediate it. They didn't show or say anything about the PostgreSQL alerts," he told us. ®
