In BigQuery, permissions are granted at the dataset level, not at the table or view level.
To restrict access to a filtered version of a table, use views in a separate dataset.
Example: Creating a view with limited data access for different teams in BigQuery.
Steps to implement: Create two datasets, create a table in one dataset, insert data, create a view in another dataset, and grant permissions to the view dataset only.
Pros of this approach: Granular control, enhanced security, clear separation of data.
Cons: Slightly more setup and management, cross-dataset access may need careful permission handling.
Note: Grant the view's dataset service account permission to read the base dataset.
Using views in a separate dataset allows for limited data access in BigQuery, aligning with the platform's security model.
