Google Data Catalog JDBC Driver

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



Integrate connectivity to Google Data Catalog data with wizards in IntelliJ.

The CData JDBC Driver for Google Data Catalog enables you to access Google Data Catalog as a JDBC data source, providing integration with rapid development tools in IDEs. This article shows how to use the data source configuration wizard to connect to Google Data Catalog data in IntelliJ.

Create a JBDC Data Source for Google Data Catalog

Follow the steps below to add the driver JAR and define connection properties required to connect to Google Data Catalog data.

  1. In the Data Sources window, right-click and then click Add Data Source -> DB Data Source.
  2. In the Data Source Properties dialog that appears, the following properties are required:

    • JDBC Driver Files: Click the button next to this menu to add the JDBC Driver file cdata.jdbc.googledatacatalog.jar, located in the installation directory.
    • JDBC Driver Class: In this menu, select cdata.jdbc.googledatacatalog.GoogleDataCatalogDriver from the list.
    • Database URL: Enter the connection URL in the JDBC URL property. The URL must start with jdbc:googledatacatalog: and includes connection properties separated with semicolons.

      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.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the Google Data Catalog JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.googledatacatalog.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      A typical JDBC URL is the following:

      jdbc:googledatacatalog:ProjectId=YourProjectId;InitiateOAuth=GETANDREFRESH

Edit and Save Google Data Catalog Data

To discover schema information, right-click the data source you just created and click Refresh Tables. To query a table, right-click it and then click Open Tables Editor.
