Question

I’m using Resque workers to process job in a queue, I have a large number of jobs > 1M in a queue and have some of the jobs that I need to remove ( added by error). Crating the queue with the jobs was not an easy tasks, so clearing the queue using resque-web and adding the correct jobs again is not an option for me.

Appreciate any advice. Thanks!

In resque’s sources (Job class) there’s such method, guess it’s what you need 🙂

# Removes a job from a queue. Expects a string queue name, a
# string class name, and, optionally, args.
#
# Returns the number of jobs destroyed.
#
# If no args are provided, it will remove all jobs of the class
# provided.
#
# That is, for these two jobs:
#
# { 'class' => 'UpdateGraph', 'args' => ['defunkt'] }
# { 'class' => 'UpdateGraph', 'args' => ['mojombo'] }
#
# The following call will remove both:
#
#   Resque::Job.destroy(queue, 'UpdateGraph')
#
# Whereas specifying args will only remove the 2nd job:
#
#   Resque::Job.destroy(queue, 'UpdateGraph', 'mojombo')
#
# This method can be potentially very slow and memory intensive,
# depending on the size of your queue, as it loads all jobs into
# a Ruby array before processing.
def self.destroy(queue, klass, *args)
