Amazon DynamoDB JDBC Driver

Connect Java applications with the DynamoDB real-time NoSQL cloud database service. Use Amazon DynamoDB as the big data backend that powers your Java/J2EE applications.

Load the CData JDBC Driver into Google Data Fusion and create ETL processes with access live Amazon DynamoDB data.

Google Data Fusion allows users to perform self-service data integration to consolidate disparate data. Uploading the CData JDBC Driver for Amazon DynamoDB enables users to access live Amazon DynamoDB data from within their Google Data Fusion pipelines. While the CData JDBC Driver enables piping Amazon DynamoDB data to any data source natively supported in Google Data Fusion, this article walks through piping data from Amazon DynamoDB to Google BigQuery,

Upload the CData JDBC Driver for Amazon DynamoDB to Google Data Fusion

Upload the CData JDBC Driver for Amazon DynamoDB to your Google Data Fusion instance to work with live Amazon DynamoDB data. Due to the naming restrictions for JDBC drivers in Google Data Fusion, create a copy or rename the JAR file to match the following format driver-version.jar. For example: cdataamazondynamodb-2020.jar

  1. Open your Google Data Fusion instance
  2. Click the to add an entity and upload a driver
  3. On the "Upload driver" tab, drag or browse to the renamed JAR file.
  4. On the "Driver configuration" tab:
    • Name: Create a name for the driver (cdata.jdbc.amazondynamodb) and make note of the name
    • Class name: Set the JDBC class name: (cdata.jdbc.amazondynamodb.AmazonDynamoDBDriver)
  5. Click "Finish"

Connect to Amazon DynamoDB Data in Google Data Fusion

With the JDBC Driver uploaded, you are ready to work with live Amazon DynamoDB data in Google Data Fusion Pipelines.

  1. Navigate to the Pipeline Studio to create a new Pipeline
  2. From the "Source" options, click "Database" to add a source for the JDBC Driver
  3. Click "Properties" on the Database source to edit the properties

    NOTE: To use the JDBC Driver in Google Data Fusion, you will need a license (full or trial) and a Runtime Key (RTK). For more information on obtaining this license (or a trial), contact our sales team.

    • Set the Label
    • Set Reference Name to a value for any future references (i.e.: cdata-amazondynamodb)
    • Set Plugin Type to "jdbc"
    • Set Connection String to the JDBC URL for Amazon DynamoDB. For example:

      jdbc:amazondynamodb:RTK=5246...;Access Key=xxx;Secret Key=xxx;;Region=OREGON;

      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.

    • Set Import Query to a SQL query that will extract the data you want from Amazon DynamoDB, i.e.:
      SELECT * FROM Lead
  4. From the "Sink" tab, click to add a destination sink (we use Google BigQuery in this example)
  5. Click "Properties" on the BigQuery sink to edit the properties
    • Set the Label
    • Set Reference Name to a value like amazondynamodb-bigquery
    • Set Project ID to a specific Google BigQuery Project ID (or leave as the default, "auto-detect")
    • Set Dataset to a specific Google BigQuery dataset
    • Set Table to the name of the table you wish to insert Amazon DynamoDB data into

With the Source and Sink configured, you are ready to pipe Amazon DynamoDB data into Google BigQuery. Save and deploy the pipeline. When you run the pipeline, Google Data Fusion will request live data from Amazon DynamoDB and import it into Google BigQuery.

While this is a simple pipeline, you can create more complex Amazon DynamoDB pipelines with transforms, analytics, conditions, and more. Download a free, 30-day trial of the CData JDBC Driver for Amazon DynamoDB and start working with your live Amazon DynamoDB data in Google Data Fusion today.
