Hi Can we add multiple data sources using auto discovery way?

Is this for 2 separate Google Cloud accounts?

Account is same but projects are different.

I think you're able to use a single json keyfile that has access to multiple projects

@future-teacher-7046 GCP projects are separate entities

It's not currently possible to have multiple auto-discovered BigQuery connections. You would have to reference the JSON key file data directly when setting up the data source.
