Delta Sharing - 'No data' in schema

[Anske]

When creating a data share in my Databricks workspace, in the step Add data assets, one of my schemas in Unity Catalog shows 'No data' when expanding. If I expand the same schema in Unity Catalog explorer, it shows lots of tables and all tables contain data (which is shown in the preview if I attach a compute). The tables were created with in a Databricks notebook run, and are not internal tables (not shortcuts or federated queries or anything), and they were created in exactly the same way as the tables in my other schema, which shows the tables just fine when expanding in the add data assets step. See attached screenshots.

I own all catalogs, schemas and tables in the schema. Anyone seen this before, or any suggestions to fix it?

Hi,

sorry for the late reply, I went on holiday :-). 

The reason no tables are expanding is because the schema only contains materialized views and streaming tables, both of which are not supported in Delta Sharing (yet). Hopefully this answer can help someone else running into the same thing.

Hello @Anske ,

This feature is currently in private preview. You should contact your account team to have it enabled in your workspace(s).

Requirements

• Databricks Runtime (DBR) 13.3 or above
• Recipients must use Serverless SQL warehouse to query a shared streaming table if the sharing is across accounts
• Recipients can only use a UC-trusted compute (SQL warehouses + Shared Cluster) to query a shared streaming table if the sharing is within the same account.
