How to integrate Metabase with MariaDB Data

Metabase is an open source data visualization tool that allows users to create interactive dashboards. When paired with CData Connect Cloud, users can easily create visualizations and dashboards linked to live MariaDB data. This article describes how to connect to MariaDB and build a simple visualization using MariaDB data.

CData Connect provides a pure cloud-to-cloud interface for MariaDB, allowing you to easily integrate with live MariaDB data in Metabase — without replicating the data. Connect looks exactly like a SQL Server database to Metabase and uses optimized data processing out of the box to push all supported SQL operations (filters, JOINs, etc) directly to MariaDB, leveraging server-side processing to quickly return MariaDB data.

Configure MariaDB Connectivity for Metabase

Connectivity to MariaDB from Metabase is made possible through CData Connect Cloud. To work with MariaDB data from Metabase, we start by creating and configuring a MariaDB connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "MariaDB" from the Add Connection panel
3. Enter the necessary authentication properties to connect to MariaDB.

   The Server and Port properties must be set to a MariaDB server. If IntegratedSecurity is set to false, then User and Password must be set to valid user credentials. Optionally, Database can be set to connect to a specific database. If not set, the tables from all databases are reported.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add MariaDB Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to MariaDB data from Metabase.

Connect to CData Connect from Metabase

After creating the virtual database, navigate to your Metabase instance. Use the SQL Server interface to connect to Connect Cloud.

1. Navigate to the administration screen (Settings -> Admin) and click "Add Database" from the "Databases" tab
2. Configure the connection to Connect Cloud and click "Save"
   • Database type: Select "SQL Server"
   • Name: Name the connection (e.g. "MariaDB (Connect Cloud)")
   • Host: tds.cdata.com
   • Port: 14333
   • Database name: The name of the connection you just created (e.g. MariaDB1)
   • Username: A Connect Cloud username (e.g. [email protected])
   • Password: The PAT for the above Connect Cloud user
   • Click to Use a secure connection (SSL)

Execute MariaDB Data with Metabase

Once you configure the connection to Connect Cloud, you can query MariaDB and build visualizations.

1. Use the "Write SQL" tool to retrieve the MariaDB data
2. Write a SQL query based on the MariaDB connection in CData Connect Cloud, e.g.
   
   

   SELECT ShipName, ShipCity FROM Orders

3. Navigate to the "Visualization" screen, choose a visualization, and configure the visualization
