Build Greenplum-Connected ETL Processes in Google Data Fusion

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

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

Upload the CData JDBC Driver for Greenplum to Google Data Fusion

Upload the CData JDBC Driver for Greenplum to your Google Data Fusion instance to work with live Greenplum 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 -.jar. For example: cdata.jdbc.greenplum-2019.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.greenplum) and make note of the name
    • Class name: Set the JDBC class name: (cdata.jdbc.greenplum.GreenplumDriver)
  5. Click "Finish"

Connect to Greenplum Data in Google Data Fusion

With the JDBC Driver uploaded, you are ready to work with live Greenplum 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
    • Set the Label
    • Set Reference Name to a value for any future references (i.e.: cdata-greenplum)
    • Set Plugin Type to "jdbc"
    • Set Connection String to the JDBC URL for Greenplum. For example:

      jdbc:greenplum:RTK=5246...;User=user;Password=admin;Database=dbname;Server=127.0.0.1;Port=5432;

      To connect to Greenplum, set the Server, Port (the default port is 5432), and Database connection properties and set the User and Password you wish to use to authenticate to the server. If the Database property is not specified, the default database for the authenticate user is used.

      To use the JDBC Driver in Google Data Fusion, you will need to set the RTK property in the JDBC URL. You can view the licensing file included in the installation for information on how to set this property.

      Built-in Connection String Designer

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

      java -jar cdata.jdbc.greenplum.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 Greenplum, i.e.:
      SELECT * FROM Orders
  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 greenplum-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 Greenplum data into

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

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