Connect to Parallel Data in CloverDX (formerly CloverETL)

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

Connect to Parallel as a JDBC Data Source

1. Create the connection to Parallel 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.

   The Parallel API uses API Key authentication via the x-api-key request header.

   Using API Key Authentication

   Your Parallel API key is required to create a connection. To obtain your API key:

   1. Log into your Parallel account at app.parallel.ai.
   2. Navigate to Settings or API Keys in your account dashboard.
   3. Generate or copy your API key.

   After obtaining your API key, set the following connection properties:

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

   Example connection string:

   Profile=C:\profiles\Parallel.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';
   

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Parallel 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\Parallel.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';

Query Parallel 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 Parallel JDBC data source from the drop-down menu.
3. Enter the SQL query. For example:

   SELECT ,  FROM MonitorEvents WHERE MonitorId = 'mon_abc123'

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 MonitorEvents table. (You can also open this menu by right-clicking the input port for the UniversalDataWriter.)
6. Click Run to write to the file.
