BigQuery: implement defaultEncryptionConfiguration on datasets #9324
Description
This feature request is to ensure the client library supports default encryption settings on
BigQuery dataset resources.
On a dataset, defaultEncryptionConfiguration (an instance of EncryptionConfiguration) can
be used to indicate a default CMEK key that will apply to all new tables or ML models created
within the dataset. Existing models are not affected, and this can be overridden when a
(table or model) is created by specifying the settings explicitly.
For libraries that expose underlying discovery types directly, this request may be a no-op.
