1. Can an ADF pipeline outside Fabric (a pipeline created in Azure ADF Service) reference OneLake as a linked service?
2. Can an external app use non-AAD authentication, such as Shared Key authorization or SAS, to access OneLake folders using a SDK, such as Python or Ruby on Falls SDK?
3. To my undestanding, OneLake is married to Power BI workspace security. Please confirm that given that Power BI workspace don't support subfolders, more granular folder-based security is not an option? I understand that tools, such as ADF pipeline, can create subfolders, but I don't see how security can be overwritten from the containing workspace.
4. The launch presentation mentions that OneLake can be georgraphically dispersed to comply with international regulations. Please confirm that the only way this to happen would to buy Power BI capacities, assign capacities to data regions, and allocate workspaces accordingly.
