Queue Manager

Queue manager for your Rails application with support Active Job. Under the hood Redis and sorted sets.

Installation

Add this line to your application's Gemfile:

gem 'queue_manager'

And then execute:

$ bundle

Or install it yourself as:

$ gem install queue_manager

Run installer:

$ rails generate queue_manager:install

Usage

Start the queue manager

$ rake queue_manager:start

Create a new job

$ rails generate job test

Rails creates a new class TestJob into app/jobs/test_job.rb. Change it to work with the queue manager:

class TestJob < ActiveJob::Base
  queue_as :default

  def perform(task, id, **kwargs)
    # Do something later
    # ...
    task.done
  end
end

Method perform should take the following arguments:

• task - the task of the queue manager;
• id - the unique identifier of the task;
• kwargs - hash with additional arguments.

What can you do with a task:

• Remove it from the queue: task.remove or task.done
• Change the job of this task at the next start: task.job = :OtherTestJob
• Passing the additional argument for the next start: task.options = { arg2: 'var2' }

Add the task to the queue:

task = QueueManager.add_task(7, job: :TestJob, arg1: 'var1')

Until such time as the task has not yet been taken in the process, you can change its parameters through the variable task. Once the task has taken the work, control it can only TestJob and evenly until the task is again back in the lineup for the timeout.

After a certain period of time, the queue manager takes the task in processing and starts job

TestJob.perform_later(task, 7, arg1: 'var1')

To stop the queue manager, run

$ rake queue_manager:stop
