强制通道API进行轮询

问题描述

希望Moishe看到这一点：在开发模式中，频道api客户端（javascript）采取轮询......并使用非常快的轮询速率。在我周围发现后，我发现如果我设置

  goog.appengine.Socket.POLLING_TIMEOUT_MS = interval; 
  

我可以控制投票率。我想知道的是：

• 我如何知道客户端是否会在生产中进入轮询模式？


• 是否可以强制客户端进入轮询模式？


• 如果我的应用达到频道配额，会发生什么情况？ / _ah / channel / endpoint会完全停止工作吗？或者它会求助于投票？

- 谢谢

解决方案

答案：

1. 客户端永远不会进入生产中的轮询模式。
   

2. 见上面




3. 调用create_channel （）会失败，你将无法获得更多的令牌。现有的令牌（以及频道）在超时之前一直有效。

希望有所帮助！

Hopefully Moishe sees this: in development mode, the channel api client (javascript) resorts to polling... and uses a very fast polling rate. After poking around I found that if I set

goog.appengine.Socket.POLLING_TIMEOUT_MS = interval;

I can control the polling rate. What I'm wondering is:

• How do I know if/when the client is going to go into "poll mode" in production?
• Is it possible to force the client into "poll mode"?
• What happens if I reach the channel quota for my app? will the /_ah/channel/ endpoint just stop working altogether? or will it resort to polling?

-Thank you

解决方案

Answers:

1. The client will never go into polling mode in production. The implementation is completely different in prod.

2. See above

3. The call to create_channel() will fail and you won't be able to get any more tokens. Existing tokens (and hence channels) will work until they time out.

Hope that helps!
