Ed Lima makes some data available to other tools:
In today’s data-driven world, the ability to quickly expose data through modern APIs is crucial. Microsoft Fabric’s API for GraphQL combined with Materialized Lake Views offers a powerful solution that bridges the gap between your Fabric LakeHouse data and application developers who need fast, flexible access to your data.
In this guide, we’ll walk you through how to create a materialized view in a Lakehouse and expose it through a GraphQL API—all within the Microsoft Fabric ecosystem. This approach gives you the best of both worlds: the performance optimization of materialized views and the developer-friendly querying capabilities of GraphQL.
I’d say one interesting reason for why you might want to do this is to feed data to products like Teams, Power Automate, or Copilot Studio. In those cases, having the data be accessible via GraphQL makes it easier than working with finicky connectors that may or may not exist.
