CreateMap
Purpose
Specifies whether the driver creates a new map of the Google BigQuery data model when establishing the connection.
Valid Values
forceNew | notExist | no | session
Behavior
If set to forceNew, the driver deletes the current schema map specified by the SchemaMap property and creates a new one at the same location.
This causes all views, data caches, and map customizations defined in the current schema map to be lost.
If set to notExist, the driver uses the current schema map specified by the SchemaMap property. If one does not exist, the driver creates one.
If set to no, the driver uses the current schema map specified by the SchemaMap property. If one does not exist, the connection fails.
If set to session, the driver does not create or use schema map. It stores metadata in the memory.
