Shoryuken is a Ruby worker for Amazon SQS.

It has middleware based on Sidekiq, with a slightly different signature:

class MyMiddleware
  def call(worker_instance, queue, sqs_msg, body)
    puts 'Before work'
    yield
    puts 'After work'
  end
end

An important thing to note is that Shoryuken can be run in a batch mode, in which case sqs_msg and body will be arrays, see this test for an example.

It uses the AWS SQS API underneath, which is already partially tracked by ddtrace.
