Hi @pardeep7 ,

Databricks Clean rooms uses Delta Sharing to share data between collaborators. This allows collaborators to share tables, volumes, and notebooks with the central clean room without exposing the underlying raw data directly to each other. Here is a reference documentation from databricks https://docs.databricks.com/aws/en/clean-rooms#how-does-clean-rooms-work

So, ideally, Collaborator B would not be able to see any sensitive data

Hope this helps!
