使用Rails控制器接受大量请求的正确方法是什么？

Question

My app controller accepts requests from third party API (webhooks), but when it becomes 400 RPM my site goes down (too many clients). What can I do with it?

class CallbacksController < ApplicationController
def acceptor
    if params['type'] == 'confirmation' # this type is rare. only when client switches on callback
      group_setting = GroupSetting.find_by_callback_token(params[:callback_token])
      if group_setting
        group_setting.update_attribute(:use_callback, true)
        GroupSetting.new.callback_start(group_setting.group, group_setting.user)
        render text: group_setting.response_string
      else
        render text:'ok'
      end
    else
      CallbackWorker.perform_async(params[:callback_token], params['type'],
                                       params['group_id'], params['object'],
                                       params['secret'])
      render text:'ok'
    end
  end
end

It seems to me that you have a web server thread bottleneck. Could you specify which server are you using? Can you make an Apache Benchmark and post the results? Maybe a little more information on your setup could help.

If you are using WEBrick, I would advise trying with PUMA .

I would also suggest that you check out Passenger that integrates easily with NGINX or Unicorn , that can help you with load balancing your requests.
