Is there any way to connect polaris catalog from unity catalog?

Hi databricks community, I'd like to access data managed by polaris catalog through unity catalog to manage all data one place. But is there any way to connect? (I could access the data with all-purpose cluster without unity catalog.)

Hello @skd217,

As of now, there isn’t a direct way to access data managed by Polaris Catalog through Unity Catalog.

You can however use external locations: https://docs.databricks.com/en/connect/unity-catalog/cloud-storage/manage-external-locations.html#language-Catalog%C2%A0Explorer

Can you provide info on how you access polaris catalog data from databricks cluster (without UC) ? any blog ?

Can we connect to External Iceberg table and read it through Unity Catalog in Databricks ?

Hey @chandu402240 , we're looking at a very similar problem. Wondering if you were able to access the Polaris catalog from a Databricks cluster? Was the External Location documentation linked by @Alberto_Umana relevant?
