Minion
A job queue for the Mojolicious real-time web framework, with support for multiple named queues, priorities, delayed jobs, job results, retries with backoff, statistics, distributed workers, parallel processing, autoscaling, resource leak protection and multiple backends (such as PostgreSQL).
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;
use 5.20.0;
use experimental 'signatures';
plugin Minion => {Pg => 'postgresql://postgres@/test'};
# Slow task
app->minion->add_task(slow_log => sub ($job, $msg) {
sleep 5;
$job->app->log->debug(qq{Received message "$msg"});
});
# Perform job in a background worker process
get '/log' => sub ($c) {
$c->minion->enqueue(slow_log => [$c->param('msg') // 'no message']);
$c->render(text => 'Your message will be logged soon.');
};
app->start;
Just start one or more background worker processes in addition to your web server.
$ ./myapp.pl minion worker
