Google Data Catalog JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Google Data Catalog.



Use the CData JDBC Driver for Google Data Catalog and Tableau Server to visualize live Google Data Catalog data.

Tableau Server is a visual analytics platform transforming the way businesses use data to solve problems. When paired with the CData JDBC Driver for Google Data Catalog, you get access to live Google Data Catalog data within Tableau Server. This article shows how to connect to Google Data Catalog in Tableau Desktop, publish a Data Source to Tableau Server, and build a simple chart from that data.

The CData JDBC Driver enables high-speed access to live Google Data Catalog data in Tableau Server. Once you install the driver, you simply authenticate with Google Data Catalog and you can immediately start building responsive, dynamic visualizations and dashboards. By surfacing Google Data Catalog data using native Tableau data types and handling complex filters, aggregations, & other operations automatically, CData JDBC Driver grants seamless access to Google Data Catalog data.

Enable Connectivity to Google Data Catalog in Tableau Server

Start by installing the CData JDBC Driver on the machine hosting Tableau Server.

If your server is a Linux Machine:

  1. Copy cdata.jdbc.googledatacatalog.jar and cdata.tableau.googledatacatalog.lic.
  2. Place the copies in the Tableau Server Connectors folder (/opt/tableau/tableau_driver/jdbc).
  3. Restart Tableau Server.

If your server is a Windows Machine:

  1. Copy cdata.jdbc.googledatacatalog.jar and cdata.tableau.googledatacatalog.lic.
  2. Place the copy in the Tableau Server drivers directory (C:\ Program Files\Tableau\Drivers).
  3. Restart Tableau Server.

Next, install the CData JDBC Driver on the machine running Tableau Desktop. Before starting Tableau on Windows, make sure that you have placed the .jar file in the C:\Program Files\Tableau\Drivers folder. Before starting Tableau on macOS, make sure that you have placed the .jar file in the ~/Library/Tableau/Drivers folder.

Connect to Google Data Catalog in Tableau Desktop

Once the driver is installed on the Server machine, we can configure a connection to Google Data Catalog in Tableau Desktop and publish a Google Data Catalog-based Data Source to Tableau Server.

  1. Open Tableau Desktop.
  2. Click More under Connect -> To a Server.
  3. Select "Other Databases (JDBC)".
  4. Configure the connection to the data. The driver comes with a connection string builder that streamlines creating and managing the content of connection strings. Note that you will need to manually add "jdbc:googledatacatalog" to the beginning of the connection string.
  5. Click "Sign In".

Google Data Catalog uses the OAuth authentication standard. Authorize access to Google APIs on behalf on individual users or on behalf of users in a domain.

Before connecting, specify the following to identify the organization and project you would like to connect to:

  • OrganizationId: The ID associated with the Google Cloud Platform organization resource you would like to connect to. Find this by navigating to the cloud console.

    Click the project selection drop-down, and select your organization from the list. Then, click More -> Settings. The organization ID is displayed on this page.

  • ProjectId: The ID associated with the Google Cloud Platform project resource you would like to connect to.

    Find this by navigating to the cloud console dashboard and selecting your project from the Select from drop-down. The project ID will be present in the Project info card.

When you connect, the OAuth endpoint opens in your default browser. Log in and grant permissions to the application to completes the OAuth process. For more information, refer to the OAuth section in the Help documentation.

Discover Schemas and Query Data

Once you establish the connection to Google Data Catalog data, you can configure which entities to visualize.

  1. Select CData from the Database pull-down menu.
  2. Select GoogleDataCatalog from the Schema pull-down menu.
  3. Drag the tables and views you wish to visualize onto the join area. You can include multiple tables.
  4. Select Update Now or Automatically Update. Update Now lets you preview the first 10,000 rows of the data source (or enter the number of rows you want to see in the Rows text box). Automatically Update auto-loads the changes in the preview area.

Publish Data to Tableau Server

After you configure the data you wish to visualize, you can publish the Data Source to a Tableau Server instance. In Tableau Desktop:

  1. Click Server -> Sign In.
  2. Enter the URL for your Tableau Server.
  3. Authenticate with Tableau Server credentials.
  4. Click Server -> Publish Data Source and select your data source.
  5. Click Publish.
  6. Select the Project, name the Data Source, and optionally add a description.
  7. Click Publish.

This creates a new entry under the server's data source list, from which you an change the data source's permissions, view its history, and perform other management tasks.

Note that workstation connected to the same server will be able to use the same source in Tableau Desktop, even if the driver isn't installed there. Also, workbooks created directly on Tableau Server (via the web interface) can use this source.

Visualize Google Data Catalog Data in Tableau Server

With the Data Source published to Tableau Server, you are ready to visualize Google Data Catalog data.

  1. Login to your Tableau Server instance.
  2. Connect to the remote source using the Search for Data -> Tableau Server in the Connect sidebar.
  3. Click the published Data Source.
  4. Click New Workbook.
  5. In the workbook, Google Data Catalog fields are listed as Dimensions and Measures, depending on the data type. The CData JDBC Driver discovers data types automatically, allowing you to leverage the powerful data processing and visualization features of Tableau.
  6. Drag a field from the Dimensions or Measures area to Rows or Columns. Tableau creates column or row headers.
  7. Select one of the chart types from the Show Me tab. Tableau displays the chart type that you selected.

Using the CData JDBC Driver for Google Data Catalog with Tableau Server, you can easily create robust visualizations and reports on Google Data Catalog data. Download a free, 30-day trial and get started today.
