Connect to Phoenix Data in CloverDX (formerly CloverETL)

Transfer Phoenix data using the visual workflow in the CloverDX data integration tool.

The CData JDBC Driver for Phoenix enables you to use the data transformation components in CloverDX (formerly CloverETL) to work with Phoenix as sources. In this article, you will use the JDBC Driver for Phoenix to set up a simple transfer into a flat file.

Connect to Phoenix as a JDBC Data Source

  1. Create the connection to Phoenix data. In a new CloverDX graph, right-click the Connections node in the Outline pane and click Connections -> Create Connection. The Database Connection wizard is displayed.
  2. Click the plus icon to load a driver from a JAR. Browse to the lib subfolder of the installation directory and select the cdata.jdbc.apachephoenix.jar file.
  3. Enter the JDBC URL.

    Connect to Apache Phoenix via the Phoenix Query Server. Set the Server and Port (if different from the default port) properties to connect to Apache Phoenix. The Server property will typically be the host name or IP address of the server hosting Apache Phoenix.

    Authenticating to Apache Phoenix

    By default, no authentication will be used (plain). If authentication is configured for your server, set AuthScheme to NEGOTIATE and set the User and Password properties (if necessary) to authenticate through Kerberos.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.apachephoenix.jar

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

    A typical JDBC URL is below:

    jdbc:apachephoenix:Server=localhost;Port=8765;

Query Phoenix Data with the DBInputTable Component

  1. Drag a DBInputTable from the Readers selection of the Palette onto the job flow and double-click it to open the configuration editor.
  2. In the DB connection property, select the Phoenix JDBC data source from the drop-down menu.
  3. Enter the SQL query. For example: SELECT Id, Column1 FROM MyTable WHERE Id = '123456'

Write the Output of the Query to a UniversalDataWriter

  1. Drag a UniversalDataWriter from the Writers selection onto the jobflow.
  2. Double-click the UniversalDataWriter to open the configuration editor and add a file URL.
  3. Right-click the DBInputTable and then click Extract Metadata.
  4. Connect the output port of the DBInputTable to the UniversalDataWriter.
  5. In the resulting Select Metadata menu for the UniversalDataWriter, choose the MyTable table. (You can also open this menu by right-clicking the input port for the UniversalDataWriter.)
  6. Click Run to write to the file.
