Description

We are updating the TDS (Tabular Data Stream) connection behavior in Fabric Warehouse to ensure consistent and predictable connections based on the specified Initial Catalog value.Previously, connections with an empty or invalid database name could redirect users to a random data warehouse. With this update, connections now honor the target database explicitly or throw validation errors when the database does not exist.
