Rocket Job 4

Rocket Job Pro is now open sourced and included within Rocket Job.

The RocketJob::Batch plugin now adds batch processing capabilites to break up a single task into many concurrent workers processing slices of the entire job at the same time.

Example:

class MyJob < RocketJob::Job
  include RocketJob::Batch

  self.description         = "Reverse names"
  self.destroy_on_complete = false
  self.collect_output      = true

  # Method to call by all available workers at the same time.
  # Reverse the characters for each line: 
  def perform(line)
    line.reverse
  end
end

Upload a file for processing, for example names.csv which could contain:

jack
jane
bill
john
blake
chris
dave
marc

To queue the above job for processing:

job = MyJob.new
job.upload('names.csv')
job.save!

Once the job has completed, download the results into a file:

job.download('names_reversed.csv')

Upgrading to V3

V3 replaces MongoMapper with Mongoid which supports the latest MongoDB Ruby client driver.

Upgrading Mongo Config file

Replace mongo.yml with mongoid.yml.

Start with the sample mongoid.yml.

For more information on the new Mongoid config file.

Note: The rocketjob and rocketjob_slices clients in the above mongoid.yml file are required.

Other changes

• Arguments are no longer supported, use fields for defining all named arguments for a job.

• Replace usages of rocket_job do to set default values:

  rocket_job do |job|
    job.priority = 25
  end

With:

  self.priority = 25

• Replace key with field when adding attributes to a job:

  key :inquiry_defaults, Hash

With:

  field :inquiry_defaults, type: Hash, default: {}

• Replace usage of public_rocket_job_properties with the user_editable option:

field :priority, type: Integer, default: 50, user_editable: true
