IBM Cloudant Icon Cloudant JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with IBM Cloudant NoSQL databases.

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

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

Upload the CData JDBC Driver for Cloudant to Google Data Fusion

Upload the CData JDBC Driver for Cloudant to your Google Data Fusion instance to work with live Cloudant 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: cdatacloudant-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.cloudant) and make note of the name
    • Class name: Set the JDBC class name: (cdata.jdbc.cloudant.CloudantDriver)
  5. Click "Finish"

Connect to Cloudant Data in Google Data Fusion

With the JDBC Driver uploaded, you are ready to work with live Cloudant 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-cloudant)
    • Set Plugin Type to "jdbc"
    • Set Connection String to the JDBC URL for Cloudant. For example:

      jdbc:cloudant:RTK=5246...;User=abc123; Password=abcdef;

      Set the following connection properties to connect to Cloudant:

      • User: Set this to your username.
      • Password: Set this to your password.

      Built-in Connection String Designer

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

      java -jar cdata.jdbc.cloudant.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 Cloudant, i.e.:
      SELECT * FROM Movies
  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 cloudant-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 Cloudant data into

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

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