Connect to Amazon DynamoDB Data and Transfer Data in Talend

Integrate Amazon DynamoDB data with standard components and data source configuration wizards in Talend Open Studio.

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

Connect to Amazon DynamoDB in Talend as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to Amazon DynamoDB:

  1. Add a new database connection to Amazon DynamoDB 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.

    The connection to Amazon DynamoDB is made using your AccessKey, SecretKey, and optionally your Domain and Region. Your AccessKey and SecretKey can be obtained on the security credentials page for your Amazon Web Services account. Your Region will be displayed in the upper left-hand corner when you are logged into DynamoDB.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.amazondynamodb.jar

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

    A typical JDBC URL is below:

    jdbc:amazondynamodb:Access Key=xxx;Secret Key=xxx;Domain=amazonaws.com;Region=OREGON;
  4. Enter the path to the cdata.jdbc.amazondynamodb.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 Lead Table to a Flat File

You can follow the procedure below to transfer the Lead 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 Lead tJDBCInput component and drag a vector to the output file.

Run the project to transfer the data.
