Short-live token from Unity Catalog

[AdventureAce]

What is this short-lived token shared by unity-catalog in step 4 and 5 here? And how does the cloud storage authenticate the token generated by unity catalog?

Hi @AdventureAce, The short-lived token shared by Unity Catalog in steps 4 and 5 is a security measure. It’s designed to expire after a certain period, reducing risk. When using cloud storage, the token is authenticated by the system based on its expiration time. If the token has expired, a new one can be granted more easily than investigating improper token lif...¹. For more details on Unity Catalog setup, you can refer to the Databricks documentation.
