Thank you for your help @MoJaMa 
We have a unified endpoint that is S3-compatible and connects to multiple data sources. Those data sources can be in the cloud or on-prem, and the location of the data doesn’t matter to the user. The goal of the unified endpoint is multiple things: simplicity, unified access, and improved performance.

We can successfully connect today using s3a path-style access with access keys and secret keys, and we are able to read and write data at the Spark level. We now want to understand how our setup can be supported with Unity Catalog.
