推荐答案

我建议使用 Gearman 服务器，它的性能相当不错稳定，它完全在Symfony2之外，您必须启动并运行服务器(不知道您的托管选项是什么)，但是它可以完美地分配作业.在最薄的版本中，它只是将所有作业保留在内存中，但是您可以将其配置为使用sqlite数据库作为备份，因此，由于任何原因，服务器重新启动或Gearman守护进程中断，您都可以再次启动它，并且您的作业将得以保留.我知道它已经在非常大的负载下进行了测试(每秒增加1000个作业)，并且它已经成为现实.从两年前的经验来看，现在这可能更稳定了，我们通过Gearman将ZF应用程序中一些长期运行的任务卸载到后台处理中.从下面的图片来看，它的工作原理应该是不言而喻的:

I would recomment Gearman server, it prooved quite stable, it's totally outside of Symfony2, and you have to have server up and running (don't know what your hosting options are), but it distribues jobs perfectly. In skiniest version, it just keeps all jobs in-memory, but you can configure it to use sqlite database as backup, so for any reason server reboots, or gearman deamon breaks, you can just start it again, and your jobs will be perserved. I konw it has been tested with very large loads (adding up 1k jobs per second), and it stood it's ground. It's probably more stable nowdays, I'm speaking from experience 2 yrs ago, where we offloaded some long-running tasks in ZF application to background processing via Gearman. It should be quite self-explanitory how it works from image below:
