This property species whether to connect to the Google Data Catalog when the connection is opened.
When set to true, a connection will be made to Google Data Catalog when the connection is opened. This property enables the Test Connection feature available in various database tools.
This feature acts as a NOOP command as it is used to verify a connection can be made to Google Data Catalog and nothing from this initial connection is maintained.
Setting this property to false may provide performance improvements (depending upon the number of times a connection is opened).
