Uniqueness across workers

[mensfeld]

Is there an option to realize uniquness across workers without hacking the digestable_hash method? I know there's an option to ensure uniqueness across queues but what about workers?

[mensfeld]

quick hack to fix that issue:

module SidekiqUniqueJobs
  class UniqueArgs
    def digestable_hash
      hash = @item.slice(CLASS_KEY, QUEUE_KEY, UNIQUE_ARGS_KEY)
      hash.delete(QUEUE_KEY) if unique_on_all_queues?
      hash.delete(CLASS_KEY) # this line makes difference
      hash
    end
  end
end

Never thought of that. What is the use case more specifically?

@mhenrixon I have a bunch of workers (different) that operate on the same resource and I would love to be able to ensure that only one is working on it at the same time. Situation in rare but can happen.

@mhenrixon thank you. You've made my day with that one!
