Connect to Mailgun Data in RapidMiner

This article shows how you can easily integrate the CData JDBC driver for Mailgun into your processes in RapidMiner. This article uses the CData JDBC Driver for Mailgun to transfer Mailgun data to a process in RapidMiner.

Connect to Mailgun in RapidMiner as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to Mailgun:

1. Add a new database driver for Mailgun: Click Connections -> Manage Database Drivers.
2. In the resulting wizard, click the Add button and enter a name for the connection.
3. Enter the prefix for the JDBC URL:

   jdbc:api:
   

4. Enter the path to the cdata.jdbc.api.jar file, located in the lib subfolder of the installation directory.
5. Enter the driver class:

   cdata.jdbc.api.APIDriver
   

   
6. Create a new Mailgun connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the Mailgun driver you configured previously.
9. Enter your connection string in the Host box.

   Start by setting the Profile connection property to the location of the Mailgun Profile on disk (e.g. C:\profiles\Mailgun.apip). Next, set the ProfileSettings connection property to the connection string for Mailgun (see below).

   Mailgun API Profile Settings

   Generate an API key in your Mailgun account by selecting Account Settings > API Security > Create Key from the account dropdown menu.

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Mailgun 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 connection string is below:

   Profile=C:\profiles\Mailgun.apip;ProfileSettings='Password=your_api_key';
   

10. Enter your username and password if necessary.

You can now use your Mailgun connection with the various RapidMiner operators in your process. To retrieve Mailgun data, drag the Retrieve operator from the Operators view. With the Retrieve operator selected, you can then define which table to retrieve in the Parameters view by clicking the folder icon next to the "repository entry." In the resulting Repository Browser, you can expand your connection node to select the desired example set.

Finally, wire the output to the Retrieve process to a result, and run the process to see the Mailgun data.
