access views in delta share

[lramkris1204]

I created a view in the delta share and tried to access but I get a response from server stating 'INVALID_PARAMETER_VALUE, 'message ': could not retrieve from share because table with type VIEW is currently unsupported in Delta Sharing protocol. Could you please let me know if there are any alternate ways in which the underlying query of the view itself can be embedded in the url that is being sent to the delta share. Appreciate your help and support on this context with an example code.

Hi,
I had the same issue. Apparently, the VIEW only works with Databricks to Databricks but if you want to access view from different environment then it is not supported right now with Delta Sharing Protocol.
You can only access table from non Databricks environment.

Curious, did you try materialized views or just plain vanilla views? We were considering a solution with views.

To answer my own question...

You're not yet currently able to add Materialized Views to a share (Receive error "Sharing materialized views is not supported yet" in AWS Databricks).

When attempting to read a normal view which you are able to add to a share in the current version of Databricks you receive the error below indicating Views are unsupported.

I'm running the following...

AWS Databricks where the share originated from

and Python program on local machine as client with the following...

Name: delta-sharing
Version: 1.0.5 (latest)

Name: databricks-spark
Version: 3.2.0 (latest)

Name: databricks-connect
Version: 14.3.2 (latest)

by any chance, does anyone know if it this is on the roadmap?

It would be great to have this feature from our end as well
