Data source properties

The Spotfire connector for Dremio does not have built-in controls for setting and changing data source properties.

When you create or edit a connection to Dremio, you use a DSN (Data Source Name) on your computer. From the DSN, Spotfire imports the connection string information about how to connect to the data source. See Using DSNs to create data connections.
