• Apache Kafka version 0.8.1.1 installed and running.

• JRuby installed.

This gem is primarily used to wrap most of the Kafka 0.8.1.1 high level consumer and Kafka 0.8.1.1 producer API into jruby. The Kafka Consumer Group Example is pretty much ported to this library.

This package is now distributed via RubyGems.org but you can build it using the following instructions.

From the root of the project run:

$ bundle install
$ rake setup jar package

You can run the following to install the resulting package:

$ gem install jruby-kafka*.gem

Add this line to your application's Gemfile:

gem 'jruby-kafka'

If you want to run the tests, make sure you already have downloaded Kafka 0.8.X, followed the kafka quickstart instructions and have KAFKA_PATH set in the environment.

make a producer

require 'jruby-kafka'

producer_options = {:topic_id => "test", :broker_list => "localhost:9092"}
producer = Kafka::Producer.new(producer_options)
producer.connect()
producer.sendMsg(nil, "here's a test")

then a consumer

require 'jruby-kafka'
queue = SizedQueue.new(20)
group = Kafka::Group.new(options)
group.run(1,queue)
Java::JavaLang::Thread.sleep 3000

#just gets first 20 things & prints out
until queue.empty?
  puts(queue.pop)
end

group.shutdown()
