Minion is a job queue for the Mojolicious real-time web framework with support for multiple backends.
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
Note that this whole distribution is EXPERIMENTAL and will change without warning!
Most of the API is not changing much anymore, but you should wait for a stable 1.0 release before using any of the modules in this distribution in a production environment.
Minion inherits all events from Mojo::EventEmitter and can emit the following new ones.
$minion->on(worker => sub { my ($minion, $worker) = @_; ... });
Emitted when a new worker is created.
$minion->on(worker => sub { my ($minion, $worker) = @_; my $id = $worker->id; say "Worker $$:$id started."; });
Minion implements the following attributes.
my $app = $minion->app; $minion = $minion->app(MyApp->new);
Application for job queue, defaults to a Mojo::HelloWorld object.
my $backend = $minion->backend; $minion = $minion->backend(Minion::Backend::File->new);
Backend, usually a Minion::Backend::File or Minion::Backend::Mango object.
my $after = $minion->remove_after; $minion = $minion->remove_after(86400);
Amount of time in seconds after which jobs that have reached the state finished will be removed automatically by "repair", defaults to 864000 (10 days).
finished
864000
my $tasks = $minion->tasks; $minion = $minion->tasks({foo => sub {...}});
Registered tasks.
Minion inherits all methods from Mojo::EventEmitter and implements the following new ones.
$minion = $minion->add_task(foo => sub {...});
Register a new task.
my $id = $minion->enqueue('foo'); my $id = $minion->enqueue(foo => [@args]); my $id = $minion->enqueue(foo => [@args] => {priority => 1});
Enqueue a new job with inactive state. You can also append a callback to perform operation non-blocking.
inactive
$minion->enqueue(foo => sub { my ($minion, $err, $id) = @_; ... }); Mojo::IOLoop->start unless Mojo::IOLoop->is_running;
These options are currently available:
delay => 10
Delay job for this many seconds from now.
priority => 5
Job priority, defaults to 0.
0
my $job = $minion->job($id);
Get Minion::Job object without making any changes to the actual job or return undef if job does not exist.
undef
my $minion = Minion->new(File => '/Users/sri/minion.data');
Construct a new Minion object.
$minion->perform_jobs;
Perform all jobs, very useful for testing.
$minion = $minion->repair;
Repair worker registry and job queue if necessary. All processes running this method and workers on this host should be owned by the same user, so they can check which workers are still alive with signals.
$minion = $minion->reset;
Reset job queue.
my $stats = $minion->stats;
Get statistics for jobs and workers.
my $worker = $minion->worker;
Build Minion::Worker object.
