After you install the Snowflake OCF connector, configure the connection to the Snowflake data source.
Follow these steps:
Provide Access¶
On the Access tab, set the data source visibility using these options:
Public Data Source—The data source will be visible to all users of the catalog.

You can add new Data Source Admin users in the Data Source Admins section.

Perform the configuration on the General Settings tab.
