Bisques is a client library for Amazon SQS (Simple Queue Service). It is implemented using httpclient (github.com/nahi/httpclient).

To interact with SQS initialize a Bisques::Client object.

The following scripts will result in the producer printing 10 numbers from the fibonacci sequence, with the consumer script doing the actual calculation.

require 'bisques'

Bisques::AwsCredentials.default(aws_key, aws_secret)
client = Bisques::Client.new('us-east-1')
number_queue = client.get_or_create_queue('numbers')
result_queue = client.get_or_create_queue('results')

1.upto(10).each{|n| number_queue.post_message({"number" => n}) }

10.times do
  puts result_queue.retrieve_one.inspect
end

require 'bisques'

Bisques::AwsCredentials.default(aws_key, aws_secret)
client = Bisques::Client.new('us-east-1')
number_queue = client.get_or_create_queue('numbers')
result_queue = client.get_or_create_queue('results')

listener = Bisques::QueueListener.new(number_queue)
listener.listen do |message|
  result = fib(message["number"])
  result_queue.post_message({"result" => result})
  message.delete
end

while true; sleep 1; end
