How to return early or finish a job without further iterations and retries?

I tried to find it in the docs but couldn't.

Let's say you have a job that iterates over N elements and midway you decided that you don't want to iterate over the remaining items and want to exit the job successfully (without retries). How to achieve this, I couldn't find it in the docs but it seems like someone must have already faced this problem before.

def each_iteration(items)
  if smth
    do_smth_with_items
  else
    end_this_job
  end
end

throw(:abort) should do the trick:

job-iteration/lib/job-iteration/iteration.rb

Lines 155 to 157 in ae5828f

	completed = catch(:abort) do
	iterate_with_enumerator(enumerator, arguments)
	end

ThrottleEnumerator uses it for example, and throwing abort without additional data is unit tested.

I see @bdewater it's very simple, thanks. Does it make sense to document this, cause it's a bit hidden and even obscure if someone doesn't know of throw and catch - which are rarely used 🤔

I think, PR is welcome.
