CData Connect



Use CData Connect to create a virtual MySQL database for Databricks data and create an interactive dashboard in Metabase from Databricks 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 Databricks data. This article describes how to create a virtual database for Databricks and build a simple visualization using Databricks data.

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

Create a Virtual MySQL Database for Databricks Data

CData Connect Cloud uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Log into Connect Cloud and click Databases.
  2. Select "Databricks" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Databricks.

    To connect to a Databricks cluster, set the properties as described below.

    Note: The needed values can be found in your Databricks instance by navigating to Clusters, and selecting the desired cluster, and selecting the JDBC/ODBC tab under Advanced Options.

    • Server: Set to the Server Hostname of your Databricks cluster.
    • HTTPPath: Set to the HTTP Path of your Databricks cluster.
    • Token: Set to your personal access token (this value can be obtained by navigating to the User Settings page of your Databricks instance and selecting the Access Tokens tab).
  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

Connect to CData Connect from Metabase

After creating the virtual database, navigate to your Metabase instance. Use the MySQL interface to connect to CData Connect.

  1. Navigate to the administration screen (Settings -> Admin) and click "Add Database" from the "Databases" tab
  2. Configure the connection to CData Connect and click "Save"
    • Database type: Select "MySQL"
    • Name: Name the connection (e.g. "Databricks (CData Connect)")
    • Host: The URL of your Connect instance (e.g. https://myinstance.cdatacloud.net)
    • Port: The port of the MySQL endpoint for your Connect instance (e.g. 3306)
    • Database name: The name of the virtual database you just created (e.g. Databricks1)
    • Username: A CData Connect username
    • Password: The password for the above CData Connect user
    • Click to Use a secure connection (SSL)

Query Databricks Data with Metabase

Once you configure the connection to CData Connect, you can query Databricks and build visualizations.

  1. Use the "Write SQL" tool to retrieve the Databricks data
  2. Write a SQL query based on the virtual database, e.g.

    SELECT City, CompanyName FROM Customers WHERE Country = 'US'
  3. Navigate to the "Visualization" screen, choose a visualization, and configure the visualization
