Create Informatica Mappings From/To a JDBC Data Source for Phoenix

Informatica provides a powerful, elegant means of transporting and transforming your data. By utilizing the CData JDBC Driver for Phoenix, you are gaining access to a driver based on industry-proven standards that integrates seamlessly with Informatica's powerful data transportation and manipulation features. This tutorial shows how to transfer and browse Phoenix data in Informatica PowerCenter.

Deploy the Driver

To deploy the driver to the Informatica PowerCenter server, copy the CData JAR and .lic file, located in the lib subfolder in the installation directory, to the following folder: Informatica-installation-directory\services\shared\jars\thirdparty.

To work with Phoenix data in the Developer tool, you will need to copy the CData JAR and .lic file, located in the lib subfolder in the installation directory, into the following folders:

• Informatica-installation-directory\client\externaljdbcjars
• Informatica-installation-directory\externaljdbcjars

Create the JDBC Connection

Follow the steps below to connect from Informatica Developer:

1. In the Connection Explorer pane, right-click your domain and click Create a Connection.
2. In the New Database Connection wizard that is displayed, enter a name and Id for the connection and in the Type menu select JDBC.
3. In the JDBC Driver Class Name property, enter:

   cdata.jdbc.apachephoenix.ApachePhoenixDriver

4. In the Connection String property, enter the JDBC URL, using the connection properties for Phoenix.

   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 connection string is below:

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

Browse Phoenix Tables

After you have added the driver JAR to the classpath and created a JDBC connection, you can now access Phoenix entities in Informatica. Follow the steps below to connect to Phoenix and browse Phoenix tables:

1. Connect to your repository.
2. In the Connection Explorer, right-click the connection and click Connect.
3. Clear the Show Default Schema Only option. 👁 The driver models Phoenix entities as relational tables. (Salesforce is shown.)
   

You can now browse Phoenix tables in the Data Viewer: Right-click the node for the table and then click Open. On the Data Viewer view, click Run.

Create Phoenix Data Objects

Follow the steps below to add Phoenix tables to your project:

1. Select tables in Phoenix, then right-click a table in Phoenix, and click Add to Project.
2. In the resulting dialog, select the option to create a data object for each resource.
3. In the Select Location dialog, select your project.

   Create a Mapping

   Follow the steps below to add the Phoenix source to a mapping:

   1. In the Object Explorer, right-click your project and then click New -> Mapping.
   2. Expand the node for the Phoenix connection and then drag the data object for the table onto the editor.
   3. In the dialog that appears, select the Read option.

   Follow the steps below to map Phoenix columns to a flat file:

   1. In the Object Explorer, right-click your project and then click New -> Data Object.
   2. Select Flat File Data Object -> Create as Empty -> Fixed Width.
   3. In the properties for the Phoenix object, select the rows you want, right-click, and then click copy. Paste the rows into the flat file properties.
   4. Drag the flat file data object onto the mapping. In the dialog that appears, select the Write option.
   5. Click and drag to connect columns.

   To transfer Phoenix data, right-click in the workspace and then click Run Mapping.
