Connect to Pinecone Data in RapidMiner

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

Connect to Pinecone in RapidMiner as a JDBC Data Source

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

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

   Authentication

   To authenticate to Pinecone, and connect to your own data or to allow other users to connect to their data, you can use API Key authentication.

   Using API Key Authentication

   To authenticate using an API Key, you need to obtain your API Key from your Pinecone console at https://app.pinecone.io/.

   You can then connect by setting the AuthScheme to APIKey and providing your API key:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your API key from Pinecone.

   Example connection strings:

   Standard API Key Configuration:

   Profile=C:\profiles\Pinecone.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key;APIVersion=2025-10';
   

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Pinecone 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\Pinecone.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key;APIVersion=2025-10';
   

10. Enter your username and password if necessary.

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