Arb::Thread

A simple "thread pool" for parallel tasks.

Add this line to your application's Gemfile:

gem 'arb-thread'

And then execute:

$ bundle

Or install it yourself as:

$ gem install arb-thread

To illustrate, let's take the example of "The Ticket model".

 require 'arb/thread'

 #Generate 8000 tickets here.
 source=(1..8000).to_a.map{|i| "ticket - #{i}"}

 #Use 30 ticket windows to sell tickets in parallel(30 threads in fact).
 Thread.parallel(30) do |dispatcher|
   8000.times do
     dispatcher.new_task do |lock|
       #The lock is a just a Mutex instance stored in dispatcher for handy usage.
       #You can use an external Mutex to synchronize if you like.
       lock.synchronize do
         #Sell ticket here.
         puts source.pop
       end
       sleep 3+rand(3)
     end
   end

 end

For detailed usage, run

$ gem unpack arb-thread

and dig into the class Arb::Thread::TaskDispatcher.
