Connect to ZenRows Data in RapidMiner

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

Connect to ZenRows in RapidMiner as a JDBC Data Source

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

1. Add a new database driver for ZenRows: 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 ZenRows connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the ZenRows 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 ZenRows Profile on disk (e.g. C:\profiles\ZenRows.apip). Next, set the ProfileSettings connection property to the connection string for ZenRows (see below).

   ZenRows API Profile Settings

   To use the ZenRows API, you need to obtain an API key from your ZenRows account. Navigate to the ZenRows dashboard at app.zenrows.com and copy your API key from the account settings.

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

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

   Built-in Connection String Designer

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

10. Enter your username and password if necessary.

You can now use your ZenRows connection with the various RapidMiner operators in your process. To retrieve ZenRows 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 ZenRows data.
