perl-Minion (A high performance job queue for Perl)

 It has support for multiple named queues, priorities, high priority
fast lane, delayed jobs, job dependencies, job progress, job
results, retries with backoff, rate limiting, unique jobs, expiring
jobs, statistics, distributed workers, parallel processing,
autoscaling, remote control, Mojolicious admin ui, resource leak
protection and multiple backends (such as Postgres.)

To get perl-Minion working, you will need to install a backend.
Minion automatically installs a postgres connector, but there
are other backends available for other databases, such as
Mongo, mysql, SQLite, and Redis. Postgres isn't a hard requirement
even though the postgres connector is installed, since the backend
is something you select at run time. To get it working with postgres,
you'll need to install the Mojo::Pg module with the perl-Mojo-Pg
slackbuild.
