Interactive CU usage when connecting SSMS/VS Code to Fabric Database
Hello! I'm testing out the database in Fabric and I'm really surprised of the CU usage, it's eating up all available resources. It's an F2 license. When I'm connected to the database with SSMS...
Hi agranaas
Tools like SSMS/VS Code often run background queries (e.g., fetching metadata for IntelliSense, refreshing object explorer, checking session status). These lightweight queries can spike CU usage on low-tier capacities (F2).The F2 SKU has minimal CU allocation (2 CUs). Even minor background activity can max out resources. Higher SKUs (F4+) buffer this better.

Do you have any idea why the warehouse does not behave in the same way?
Open connections to the warehouse has no impact on CU usage from what I have seen.
