How to Process Items in an Array in Parallel using Ruby (and open-uri)

Question

I am wondering how i can go about opening multiple concurrent connections using open-uri? i THINK I need to use threading or fibers some how but i\'m not sure.

Answer 1

module MultithreadedEach
  def multithreaded_each
    each_with_object([]) do |item, threads|
      threads << Thread.new { yield item }
    end.each { |thread| thread.join }
    self
  end
end

Usage:

arr = [1,2,3]

arr.extend(MultithreadedEach)

arr.multithreaded_each do |n|
  puts n # Each block runs in it's own thread
end
