Snowflake connection

Pre-configuration task: Setting up Snowflake roles, warehouses, and privileges

For a seamless connection between Snowflake and, you need to ensure the following settings are configured properly:

  1. The user to be used for the Snowflake connection should have a default Warehouse default warehouse set within Snowflake. All queries launched against Snowflake with this connection will use this warehouse for computing.

  2. If the user specified in the Snowflake connection does not have a default role set in Snowflake, the connection will default to the Public role. It may limit the privileges to access and query data.

  3. If a default role is established for the Snowflake user, the role will be used by the connection.

  4. To create a virtualized connection to a table or view, the user needs to have USAGE privileges on the database and schema, and SELECT privileges on the table or view.

  5. The default database, if defined in the connection window, should be specified using all UPPER CASE letters.

Configuring a connection to Snowflake

To set a connection:

  1. On the Organization profile page, go to the Settings tab > Connection manager section.

  2. Click the Add connection button.

  3. In the Add an organization-level connection window, select Snowflake.

  4. In the Add a new Snowflake connection window, set the following:

    • Use unencrypted private key: Select this option if you prefer to use an unencrypted private key rather than a password. After selecting this option, input the key into the Connection private key field.

  5. Click the Test Snowflake configuration button to test your configuration. It is essential to test your connections to ensure the application can successfully connect to the source system.

  6. Click Configure to save your configuration.

  7. The saved configuration is added to the list of Organization-level connections. From here, you have the option to edit or delete a connection. Although you will see a Create task option for a connection, it is not applicable for data virtualization and data extraction and should be disregarded. This Create task option was originally intended for metadata collection, but this feature has since been deprecated and should not be used. To configure metadata collection, use the Metadata collectors configuration available in the product.


Configuring advanced SSH Tunnel connection options

For enhanced security, the application supports configuring an SSH tunnel as part of your connection setup. This method provides a secure link between your database server and, utilizing an SSH-secured pathway.

Editing connections

To edit a connection:

  1. Locate the connection you want to edit.

  2. Click the Three dot menu and select Edit connection.

  3. In the Edit connection window, make the desired changes. Note that when you are editing a connection, you are required to provide the sensitive information for the connection again, for example, Connection password.

  4. After modifying the connection details, click the Test configuration button to recheck the set up and ensure it is functioning as expected.

Deleting connections

Deleting a connection causes all dependent resources, including virtualized connections and queries, to lose access to their data source. While the resources persist, they cannot access or retrieve data without a functioning connection.

For example, If you delete the connection, the following error message will appear for the Insight:


To delete a connection:

  1. Locate the connection you want to delete.

  2. Click the Three dot menu and select Delete connection.

  3. Confirm the deletion. Once deleted the connection cannot be restored. You have to set a new connection again.
