Connect to Azure Table Data and Transfer Data in Talend

This article shows how you can easily integrate the CData JDBC driver for Azure Table into your workflow in Talend. This article uses the CData JDBC Driver for Azure Table to transfer Azure Table data in a job flow in Talend.

Connect to Azure Table in Talend as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to Azure Table:

1. Add a new database connection to Azure Table data: To add a new connection, expand the Metadata node, right-click the Db Connections node, and then click Create Connection.
2. In the resulting wizard, enter a name for the connection.

3. On the next page, select Generic JDBC from the DB Type menu and enter the JDBC URL.

   Specify your AccessKey and your Account to connect. Set the Account property to the Storage Account Name and set AccessKey to one of the Access Keys. Either the Primary or Secondary Access Keys can be used. To obtain these values, navigate to the Storage Accounts blade in the Azure portal. You can obtain the access key by selecting your account and clicking Access Keys in the Settings section.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.azuretables.jar

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

   A typical JDBC URL is below:

   jdbc:azuretables:AccessKey=myAccessKey;Account=myAccountName;
4. Enter the path to the cdata.jdbc.azuretables.jar file, located in the lib subfolder of the installation directory.
5. Right-click the connection and then click Retrieve Schema.
6. Click Next with the default options to select the tables you want to import.
7. Finish the wizard with the default options.

Output the NorthwindProducts Table to a Flat File

You can follow the procedure below to transfer the NorthwindProducts table to a flat file output component:

1. In the Table Schemas node, drag the tables to the workspace.
2. In the dialog that is displayed, select the tJDBCInput component.
3. Next, drag a tFileOutputDelimited component from the Business Intelligence tab of the Palette into the workspace.
4. Right-click the NorthwindProducts tJDBCInput component and drag a vector to the output file.

Run the project to transfer the data.
