带有sidekiq的Rails ActiveJob Job延迟6/10秒

Question

I am using Rails ActiveJob with Sidekiq. I have a Job that is supposed to execute after 5 seconds.

UserArrivalJob.set(wait: 5.seconds).perform_later(user, planet)

Only after 5 seconds the job still hasnt ran. When i look in the sidekiq web interface after those 5 seconds the job is there and it says: Not yet enqueued. After about another 6 till 10 seconds the job gets enqeued and is immediatly executed. How come that there is this delay? When i use perform now this delay is not there.

Here is my Job:

class UserArrivalJob < ActiveJob::Base
  queue_as :default

  def perform(user, planet)
    user.planet = planet
    user.save
  end
end

Answer 1

Read here . Basically I think your sidekiq poller runs every 10 seconds and it picks the job when it pools.

Answer 2

bcd was right. I set the sidekiq configuration to run the poller every 2 seconds.

environments/development.rb / environments/production.rb

Sidekiq.configure_server do |config|
  config.average_scheduled_poll_interval = 2
end
