Letterbox

A short-lived actor framework using Celluloid.

With Bundler:

gem 'letterbox'

Otherwise:

gem install letterbox

When instantiating a Letterbox::Exchange you must provide a class that will do the work. The work class' constructor should accept one argument (the "payload") and implement a perform method that performs the desired work.

You can send work to a particular address by specifying a payload and the address that should do the work. All work sent to a particular address will be processed serially.

Work spread across multiple mailboxes will be processed concurrently.

Empty addresses are cleaned up automatically once there is no more work to be done.

module MyWork

  attr_reader :payload

  def initialize(payload)
    @payload = payload
  end

  def perform
    sleep rand
    puts "Working on: #{payload}"
  end

end

e = Letterbox::Exchange.new(MyWork)

# spread 100 units of work across 10 addresses
100.times { |i| e.dispatch("payload #{i}", "a#{i % 10}") }
