%description
Minion is a job queue for the at http://mojolicious.org real-time web
framework, with support for multiple named queues, priorities, delayed
jobs, job dependencies, job results, retries with backoff, statistics,
distributed workers, parallel processing, autoscaling, remote control,
resource leak protection and multiple backends (such as at
http://www.postgresql.org).

Job queues allow you to process time and/or computationally intensive tasks
in background processes, outside of the request/response lifecycle. Among
those tasks you'll commonly find image resizing, spam filtering, HTTP
downloads, building tarballs, warming caches and basically everything else
you can imagine that's not super fast.

  use Mojolicious::Lite;

  plugin Minion => {Pg => 'postgresql://sri:s3cret@localhost/test'};

  # Slow task
  app->minion->add_task(poke_mojo => sub {
    my $job = shift;
    $job->app->ua->get('mojolicious.org');
    $job->app->log->debug('We have poked mojolicious.org for a visitor');
  });

  # Perform job in a background worker process
  get '/' => sub {
    my $c = shift;
    $c->minion->enqueue('poke_mojo');
    $c->render(text => 'We will poke mojolicious.org for you soon.');
  };

  app->start;

Background worker processes are usually started with the command
Minion::Command::minion::worker, which becomes automatically available when
an application loads the plugin Mojolicious::Plugin::Minion.

  $ ./myapp.pl minion worker

Jobs can be managed right from the command line with
Minion::Command::minion::job.

  $ ./myapp.pl minion job

To manage background worker processes with systemd, you can use a unit
configuration file like this.

  [Unit]
  Description=My Mojolicious application workers
  After=postgresql.service

  [Service]
  Type=simple
  ExecStart=/home/sri/myapp/myapp.pl minion worker -m production
  KillMode=process

  [Install]
  WantedBy=multi-user.target

Every job can fail or succeed, but not get lost, the system is eventually
consistent and will preserve job results for as long as you like, depending
on "remove_after". While individual workers can fail in the middle of
processing a job, the system will detect this and ensure that no job is
left in an uncertain state, depending on "missing_after".
