Connect to Pinecone Data in JRuby

JRuby is a high-performance, stable, fully threaded Java implementation of the Ruby programming language. The CData JDBC Driver for Pinecone makes it easy to integrate connectivity to live Pinecone data in JRuby. This article shows how to create a simple JRuby app that connects to Pinecone data, executes a query, and displays the results.

Configure a JDBC Connection to Pinecone Data

Before creating the app, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CData\CData JDBC Driver for Pinecone\lib).

JRuby natively supports JDBC, so you can easily connect to Pinecone and execute SQL queries. Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.

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.

Below is a typical JDBC connection string for Pinecone:

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

Create a JRuby App with Connectivity to Pinecone Data

Create a new Ruby file (for example: APISelect.rb) and open it in a text editor. Copy the following code into your file:

require 'java'
require 'rubygems'
require 'C:/Program Files/CData/CData JDBC Driver for Pinecone 2018/lib/cdata.jdbc.api.jar'

url = "jdbc:api:Profile=C:\profiles\Pinecone.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key;APIVersion=2025-10';"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT ,  FROM Indexes")
while (rs.next) do
  puts rs.getString(1) + ' ' + rs.getString(2)
end

With the file completed, you are ready to display your Pinecone data with JRuby. To do so, simply run your file from the command line:

jruby -S APISelect.rb
