Refresh View SchemasCData Power BI Connector for Google BigQuery 2019 - Build 19.0.7354
Allows the provider to determine up-to-date view schemas automatically.
When using BigQuery views, BigQuery stores a copy of the view schema with the view itself. However, these stored view schemas are not updated when the tables used by the view change. This means that the stored view schema can easily become out of date and cause queries using the view to fail.
By default, the connector will not use the stored view schema and will instead query the view to determine the schema used by the view. This guarantees that the schema will be up to date, although it requires the connector to start a query job to determine the columns available in a view.
You can disable this option to force the connector to use the stored view schemas. This prevents the connector from running any queries when getting a view schema, but also means that queries using the view will fail if the schema is out of date.
