Tableau Connector for MariaDB

Build 24.0.9060

Configuring a Connection

After Installing the Connector you can connect and create a Data Source for data in MariaDB.

Setting Up a Data Source

Complete the following steps to connect to the data:

  1. Under Connect | To a Server, click More....
  2. Select the data source called MariaDB by CData.
  3. Enter the information required for the connection.
  4. Click Sign In.
  5. If necessary, select a Database and Schema to discover what tables and views are available.

Using the Connection Builder

The connector makes the most common connection properties available directly in Tableau. However, it can be difficult to use if you need to use more advanced settings or need to troubleshoot connection issues. The connector includes a separate connection builder that allows you to create and test connections outside of Tableau.

There are two ways to access the connection builder:

  • On Windows, use a shortcut called Connection Builder in the Start menu, under the CData Tableau Connector for MariaDB folder.
  • You can also start the connection builder by going to the driver install directory and running the .jar file in the lib directory.

In the connection builder, you can set values for connection properties and click Test Connection to validate that they work. You can also use the Copy to Clipboard button to save the connection string. This connection string can be given to the Connection String option included in the connector connection window in Tableau.

Connecting to MariaDB

The Server and Port properties must be set to a MariaDB server. Optionally, Database can be set to connect to a specific database. If not set, the connector reports tables from all databases.

Azure AD

Azure AD is Microsoft’s multi-tenant, cloud-based directory and identity management service. It is user-based authentication that requires that you set AuthScheme to AzureAD.

Desktop Applications

CData provides an embedded OAuth application that simplifies authentication at the desktop. You can also authenticate from the desktop via a custom OAuth application, which you configure and register at the MariaDB console. For further information, see Creating a Custom OAuth Application.

Before you connect, set the following variables:

  • InitiateOAuth: GETANDREFRESH. Used to automatically get and refresh the OAuthAccessToken.
  • Custom Azure AD applications only:
    • OAuthClientId: The client Id assigned when you registered your custom OAuth application.
    • OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.
    • CallbackURL: The redirect URI defined when you registered your custom OAuth application.

When you connect, the connector opens the MariaDB'sOAuth endpoint in your default browser. Log in and grant permissions to the application. The connector then completes the OAuth process:

  1. Extracts the access token from the callback URL and authenticates requests.
  2. Obtains a new access token when the old one expires.
  3. Saves OAuth values in OAuthSettingsLocation. These values persist across connections.

When the access token expires, the connector refreshes it automatically.

LDAP

To authenticate as an LDAP user, set AuthScheme to LDAP.

Your LDAP credentials are auto-detected by default. If you want to designate a different user and account, set the following optional properties:

  • User: The user to login as.
  • Password: The user's password.
