@Md Mizanur Rahman Nayan According to Microsoft documentation on OneLake security prerequisites: "To configure OneLake security, you must be an Admin or Member in the workspace, or have Write and Reshare permissions" This means that CONTRIBUTOR cannot manage the OneLake roles. Remember that contributor has write but contributor doesn't have reshare. So effectively I think this article from @Will Needham should be corrected to remove the contributor word.

@Will Needham this section where you mention about "Implement file-based access" seems to be the OneLake security concept. Can you double check please?

@Sachin Satkalmi thank you

This question is specifically about power bi dataset. Not warehouse or lakehouse.

@Will Needham in the pipeline semantic model refresh activity, the documentation states that "By default, the semantic model refresh activity runs a full refresh when triggered from the pipeline.". Do you know whether it is possible to run an incremental semantic model refresh from the pipeline?

Isn't there a simple backup like SQL server.

@Will Needham thanks for pointing me to the warehouse restore points. Regarding lakehouse - if I do use the capacity DR method, then is there a way to rollback or recover to a previous point in time? Or is this purely a cross region DR sync.

Please can you point me to any official documentation on this topic, as the current document takes me to semantic model documentation, rather than documentation on warehouse relaironships...

@Will Needham do you mean the following is no longer the product capability? "define relationships between tables, within the Model Layouts section of the Data Warehouse (or Lakehouse SQL Endpoint)"
