You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: of_many_partitions_with_many_workers_spec.rb
    path of file: ./repos/karafka/spec/integrations/consumption/strategies/default
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

# Karafka should use more than one thread to consume independent topics partitions

setup_karafka d
    
  def consume
    # This will simulate, that the thread is busy in a bit random way, so more worker threads can
    # be occupied
    sleep(1)

    messages.each do |message|
      DT[message.partition] << Thread.current.object_id
    end
  end
