google-app-engine - 动态后端如何在 Google App Engine 中启动

Question

我们能否以编程方式启动动态后端？意味着当后端启动时，我如何通过回退到应用程序(我的意思是 app.appspot.com)来处理请求。

当我在管理控制台中手动停止后端并向其发送请求时，它不会“动态”启动

Answer 1

Dynamic backends come into existence when they receive a request, and are turned down when idle; they are ideal for work that is intermittent or driven by user activity.

Resident backends run continuously, allowing you to rely on the state of their memory over time and perform complex initialization.

我最近开始在动态后端上执行一项长时间运行的任务，并注意到前端的性能有了显着提高。我认为这是因为长时间运行的任务正在与正常用户请求竞争资源。
