* `ActiveJob::Base.deserialize` delegates to the job class
Since `ActiveJob::Base#deserialize` can be overriden by subclasses (like `ActiveJob::Base#serialize`)
this allows jobs to attach arbitrary metadata when they get serialized and read it back when they get
performed. E.g.
class DeliverWebhookJob < ActiveJob::Base
def serialize
super.merge('attempt_number' => (@attempt_number || 0) + 1)
end
def deserialize(job_data)
super(job_data)
@attempt_number = job_data['attempt_number']
end
rescue_from(TimeoutError) do |ex|
raise ex if @attempt_number > 5
retry_job(wait: 10)
end
end
