Parallelization execution of workflow tasks for CMDx.

Add this line to your application's Gemfile:

gem 'cmdx-parallel'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cmdx-parallel

CMDx::Parallel task execution leverages the Parallel gem, which automatically detects the number of available processors to maximize concurrent task execution.

class SendWelcomeNotifications < CMDx::Task
  include CMDx::Workflow

  # Default options (dynamically calculated to available processors)
  tasks SendWelcomeEmail, SendWelcomeSms, SendWelcomePush, strategy: :parallel
end

Reference the Parallel gem for all processing options.

class SendWelcomeNotifications < CMDx::Task
  include CMDx::Workflow

  # Fix number of threads
  tasks SendWelcomeEmail, SendWelcomeSms, SendWelcomePush, strategy: :parallel, in_threads: 2

  # Fix number of forked processes
  tasks SendWelcomeEmail, SendWelcomeSms, SendWelcomePush, strategy: :parallel, in_processes: 2

  # NOTE: Reactors are not supported
end

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
