Connect to Optimizely Data in JRuby

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

Configure a JDBC Connection to Optimizely 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 Optimizely\lib).

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

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

Optimizely API Profile Settings

Generate a personal API token at app.optimizely.com/v2/profile/api in your Optimizely account settings.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Optimizely 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 Optimizely:

jdbc:api:Profile=C:\profiles\Optimizely.apip;ProfileSettings='APIKey=your_api_key';

Create a JRuby App with Connectivity to Optimizely 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 Optimizely 2018/lib/cdata.jdbc.api.jar'

url = "jdbc:api:Profile=C:\profiles\Optimizely.apip;ProfileSettings='APIKey=your_api_key';"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Id, Name FROM Attributes")
while (rs.next) do
  puts rs.getString(1) + ' ' + rs.getString(2)
end

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

jruby -S APISelect.rb
