Got error when access delta sharing table with iceberg endpoint

[unidevel]

I created an iceberg table within databricks and shared it via delta sharing with token

Then I use curl command to access it with iceberg endpoint like this:

curl -X GET \
-H "Authorization: Bearer ***"\
-H "Accept: application/json" \
"https://ohio.cloud.databricks.com/api/2.0/delta-sharing/metastores/e6da0ff4-5f22-4fc4-b2e8-fe49d047c..."

But got the error below:
{"error":{"message":"Malformed request: INVALID_PARAMETER_VALUE: DS_UNSUPPORTED_TABLE_TYPE: Could not retrieve default.diamonds_iceberg from Share delta-share because table with type [Databricks managed storage] is currently unsupported in delta sharing queries.","type":"BadRequestException","code":400}}

Are there any configuration steps I missed or is it not supported? Any document I can reference to make the iceberg endpoint working?

Hi, I have found the attached documentation.

Hi @unidevel ,

It depends to whom you share - to an External Iceberg Client, or to a Databricks?

Please note that currently Databricks does not support sharing managed Iceberg tables to external Iceberg clients.

 You can share managed Iceberg tables with another Databricks workspace.

Hope it helps.

Hi, @aleksandra_ch 

I understood that currently Databricks does not support sharing managed Iceberg tables to external Iceberg clients. Is there a plan to support it, or will the current behavior remain unchanged?

Thank you.

Hi @Ji-Seung ,

Yes, this is correct. The behavior might change in the future.

Please note that it is possible to read managed Iceberg tables with external Iceberg clients via Iceberg REST catalog: https://docs.databricks.com/aws/en/external-access/iceberg

Hi @aleksandra_ch ,
Thank you for the clarification. Just to confirm, is support for sharing managed Iceberg tables with external Iceberg clients through OpenSharing currently on the Databricks roadmap, or is it only a possibility being considered without a concrete plan or timeline? I understand if there is no publicly available timeline now. 

Best regards,

Thank you @rdokala , @aleksandra_ch 

BTW, can I share managed uniformed delta table to external Iceberg clients? I tried this but get the same error, my friend tried, seems fine. I don't know what's the difference.

Best regards,
