Disbatch is a distributed, multi-language batch processing platform. This package provides both a client library and execution node implementation. 

The current packaging is a bit raw, but an earlier version of this has been successfully used in production for a number of tasks, including mass mailing, user migrations and load generation.

If you have mongod installed and running, the daemon should start without parameters or configuration, and queues and tasks can be created interactively through a ruby shell or programatically through a script:

[mberg@c6 ~]$ irb 
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'disbatch'
=> true
irb(main):003:0> q = Disbatch::Queue.create('Disbatch::Plugin::Hello')
=> #<Disbatch::Queue:0x7f9e38d78948 @id="4eea39ce250c600d5d000001", @plugin="Disbatch::Plugin::Hello">
irb(main):004:0> q.push( { 'name' => 'Matt' } )
=> #<Disbatch::Queue:0x7f9e38d78948 @id="4eea39ce250c600d5d000001", @plugin="Disbatch::Plugin::Hello">

In order to facilitate plugin development, tasks can also be executed without running an execution node; e.g.

irb(main):005:0> require 'disbatch/plugin/hello.rb'
Registered Disbatch::Plugin::Hello
irb(main):006:0> t = q.pop
=> #<Disbatch::Queue::Task:0x7f9e38d56460 @id=BSON::ObjectId('4eea3a9a250c600d5d000003'), @parameters=#<BSON::OrderedHash:0x3fcf1c6abf14 {"name"=>"Matt"}>, @queue=#<Disbatch::Queue:0x7f9e38d78948 @id="4eea39ce250c600d5d000001", @plugin="Disbatch::Plugin::Hello">>
irb(main):007:0> t.execute!
Executed task with params: #<BSON::OrderedHash:0x3fcf1c6abf14 {"name"=>"Matt"}>
=> 1
