We need to set the userenv when we process the jobs. It is useful for stats (at least) Signed-off-by: Martin Renvoize <martin.renvoize@ptfs-europe.com> Signed-off-by: Kyle M Hall <kyle@bywatersolutions.com> Signed-off-by: Tomas Cohen Arazi <tomascohen@theke.io>

=head1 NAME
|
|
|
|
background_jobs_worker.pl - Worker script that will process background jobs
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
./background_jobs_worker.pl [--queue QUEUE]
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This script will connect to the Stomp server (RabbitMQ) and subscribe to the queues passed in parameter (or the 'default' queue),
|
|
or if a Stomp server is not active it will poll the database every 10s for new jobs in the passed queue.
|
|
|
|
You can specify some queues only (using --queue, which is repeatable) if you want to run several workers that will handle their own jobs.
|
|
|
|
