Hi @HoussemBL 

When you delete a Databricks workspace, it does not directly impact the Unity Catalog or the data within it. Unity Catalog is a separate entity that manages data access and governance across multiple workspaces. Here’s what happens in your specific scenario:

1. Catalog1 Accessibility: If you delete workspace W1, Catalog1 will remain accessible in W2. Unity Catalog is designed to be a centralized governance solution, and the deletion of a workspace does not delete the catalog or its metadata. As long as the Unity Catalog instance itself is not deleted, the data and metadata within Catalog1 will remain intact and accessible from other workspaces that have been granted access, such as W2.
