Integrating Google Cloud Storage Data in Talend Cloud Data Management Platform

Qlik's Talend Cloud Data Management Platform supports various data environments, enabling analytics for smarter decisions, operational data sharing, data and application modernization, and establishing data excellence for risk reduction. When paired with the CData JDBC Driver for Google Cloud Storage, you can improve data integration, quality, and governance for your Google Cloud Storage Data. This article shows how you can easily integrate to Google Cloud Storage using a CData JDBC Driver in Talend Cloud Data Management, and then view the data for simultaneous use in your workflow.

Prerequisites

Before connecting the CData JDBC Driver to view and work with your data in Talend Cloud Data Management Platform, make sure to download and install the latest version of Talend Studio on your system. Also, ensure that you have the required prerequisites.

1. A Talend Cloud Data Management account with appropriate permissions.
2. The CData JDBC Driver for Google Cloud Storage, which can be downloaded from the CData website.

Connect to Google Cloud Storage in Talend as a JDBC data source

Access Talend Data Management Cloud

1. Run the Talend Cloud Data Management Platform installed on your local system and click on Other Login Mode. 👁 Log into Talend Cloud Data Management Platform locally
   
2. Click on Manage Connections. Set Repository to "Local" and enter the Name, Description and User E-mail in the respective spaces. Set the Workspace path and click on OK. 👁 Manage a connection.
   👁 Create a connection in Talend Data Management Cloud
   
3. Now, select the Create a new project radio button to add a new project name and click on Create. 👁 Create a new project.
   
4. The new project should appear under the Select an existing project section. Click on Open. The Talend Cloud Data Management Platform workspace opens up. 👁 Open the Talend Cloud Data Management Platform workspace.
   

Create a new connection

1. In the navigation pane, locate and expand the Metadata dropdown. Right-click on Db Connections and select Create Connection. 👁 Create a new connection in the Talend platform under Db connections.
   
2. Search for and select 'JDBC' in the Find section of the Database Connection window. Then, click on Finish. 👁 Search and select the JDBC connector.
   
3. Enter the Name, Purpose and Description of the new database in Talend where you need to load the Google Cloud Storage data. Click on Next. 👁 Enter details of the database toload the source data.
   
4. Generate a JDBC URL for connecting to Google Cloud Storage, beginning with jdbc:googlecloudstorage: followed by a series of semicolon-separated connection string properties.

   Authenticate with a User Account

   You can connect without setting any connection properties for your user credentials. After setting InitiateOAuth to GETANDREFRESH, you are ready to connect.

   When you connect, the Google Cloud Storage OAuth endpoint opens in your default browser. Log in and grant permissions, then the OAuth process completes

   Authenticate with a Service Account

   Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes.

   You need to create an OAuth application in this flow. See the Help documentation for more information. After setting the following connection properties, you are ready to connect:

   • InitiateOAuth: Set this to GETANDREFRESH.
   • OAuthJWTCertType: Set this to "PFXFILE".
   • OAuthJWTCert: Set this to the path to the .p12 file you generated.
   • OAuthJWTCertPassword: Set this to the password of the .p12 file.
   • OAuthJWTCertSubject: Set this to "*" to pick the first certificate in the certificate store.
   • OAuthJWTIssuer: In the service accounts section, click Manage Service Accounts and set this field to the email address displayed in the service account Id field.
   • OAuthJWTSubject: Set this to your enterprise Id if your subject type is set to "enterprise" or your app user Id if your subject type is set to "user".
   • ProjectId: Set this to the Id of the project you want to connect to.

   The OAuth flow for a service account then completes.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.googlecloudstorage.jar
   

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

   👁 Using the built-in connection string designer to generate a JDBC URL (Salesforce is shown.)
   

   A typical JDBC URL is below:

   jdbc:googlecloudstorage:ProjectId='project1';InitiateOAuth=GETANDREFRESH;
   

5. Enter the JDBC URL copied from CData JDBC Driver for Google Cloud Storage in Edit new database. 👁 Enter the JDBC URL (Salesforce is shown).
   

6. Click on the "(+) Add" button under Drivers. A 'newLine' will appear in the Drivers board. Click on (...) at the end of the new line, select the Install a new module radio button, and click on (...) to add the path to the JAR file, located in the 'lib' subfolder of the installation directory. Click on OK. 👁 Add a new line in Drivers board to add the path to the Google Cloud Storage JAR file (Salesforce is shown).
   👁 The lib folder which contains the Google Cloud Storage JAR file (Salesforce is shown).
   👁 Add the JAR installation path in 'Install a new module' (Salesforce is shown).
   
7. Select the Driver Class as cdata.jdbc.googlecloudstorage (JAR file obtained from your installation directory given in the previous step). 👁 Add the Driver class.
   

Test the new connection

1. Click on Check Connection. If the entered details are correct, a "Connection successful" confirmation prompt will appear. Click on "OK" and "Finish". 👁 Check the connection.
   
2. Once the connection is established, right-click on the newly created connection and select Retrieve Schema. You can use the filters as well to retrieve the data as per your requirements. Click on Next. 👁 Retrieve schema from the datasource.
   👁 Add the necessary filters.
   
3. Expand the "CData" catalog in the Schema window and select the tables you want to import from the Google Cloud Storage schema. Click on Next. 👁 Select a table from the Google Cloud Storage schema.
   
4. In the next step, select the columns you want to view from the table and click on Finish. 👁 Select the necessary columns from the selected table.
   
5. All the selected tables from the Google Cloud Storage schema are now populated under the Table Schemas section of the JDBC connection.
6. Right-click on any of the selected tables and click on Data Viewer to preview the data from the data source. 👁 Click on Data Viewer to view the source data.
   👁 Display the source table view.
