We do a lot of policy tagging in our bigquery warehouse environment. To avoid an instance of data exposure at ingestion time, we would like to request an option for policy taxonomies to be defined in the Connector schema, whereby we could populate our policy tags which would be applied and reflected in our warehouse at ingestion time. This feature would enable toggle control over policy visibility at the user level via IAM in our GCP environment. Fivetran currently offers an option to hash sensitive columns, however there is no way to toggle exposure at the user level, once the data has been ingested into the warehouse. Should hashed data be required to be exposed, the connector schema would be required to be updated and the columns re-ingested.
