- User name: user name associated with BigQuery Project
- User key file path: the path to the certificate (*.p12) that is pre-installed in the CData Virtuality Server

Below are some examples of the most common data source parameters, see the reference manual for the full list:

- `importer.useFullSchemaName=TRUE` - schema names will be prefixed to table names to avoid duplicates
- `importer.importProcedures=TRUE` - stored procedures will be imported
- `importer.useProcedureSpecificName=TRUE` - when two stored procedures being imported have identical names, an index will be appended to their names in order to avoid conflicts
