Connect to Perigon Data in CloverDX (formerly CloverETL)

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

Connect to Perigon as a JDBC Data Source

1. Create the connection to Perigon 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.api.jar file.
3. Enter the JDBC URL.

   Using API Key Authentication

   To use the Perigon API, you need to obtain an API key from your Perigon account. Navigate to the Perigon dashboard and generate an API key from your account settings.

   After setting the following connection properties, you are ready to connect:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your Perigon API key.

   Example connection string:

   Profile=C:\profiles\Perigon.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key"
   

   Available Tables

   The Perigon profile provides access to the following tables:

   • Articles - News articles retrieved from the Perigon news intelligence API
   • Headlines - Story clusters grouping related headline articles
   • Sources - News sources tracked by the Perigon news intelligence API
   • Journalists - Journalist profiles tracked by the Perigon news intelligence API

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.api.jar
   

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

   

   A typical JDBC URL is below:

   jdbc:api:Profile=C:\profiles\Perigon.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key"

Query Perigon Data with the DBInputTable Component

2. In the DB connection property, select the Perigon JDBC data source from the drop-down menu.
3. Enter the SQL query. For example:

   SELECT ,  FROM Articles WHERE  = ''

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 Articles table. (You can also open this menu by right-clicking the input port for the UniversalDataWriter.)
