Can I customise permissions granted by Dataplex "Data Roles"?

Question

I'm using Dataplex to grant users permissions to underlying BigQuery tables.

This is done using Dataplex "data roles", which grant some (not very clearly specified?) permissions on the BigQuery tables. For example, roles/dataplex.dataWriter gives some vague "write" permissions to users.

Is it possible to customise which permissions Dataplex will give to a user who is assigned this role, or will I just have to manage the permissions outside of Dataplex?

Answer 1

I've spoken to Google Support and there is no way to customise the permissions that Dataplex gives on underlying resources at this time. There is a long-term plan for this functionality.
