异步在龙卷风中如何工作？ [英] How does async work in Tornado?

问题描述

Tornado文档中的所有示例都显示了如何使用Tornado异步发出更多HTTP请求。

All examples in the Tornado documents show how we can make further HTTP requests asynchronously using Tornado.

http_client = httpclient.AsyncHTTPClient()
http_client.fetch("http://www.google.com/", handle_request)

虽然我想确保龙卷风不等待数据库的响应（获取沙发床命令）随后发送。

While I want to ensure that my tornado doesn't wait for response from database (get command of couchbase) to send next.

检查我的其他错误以了解为什么我要异步调用沙发床。

Check my other bug to understand why I want async call to couchbase.

推荐答案

据我所知，Couchbase驱动程序是不是异步驱动程序，因此无法正常工作。使数据库调用同步并尽可能快地对其进行优化。

As far as I know Couchbase driver is not an async driver so this wont work. Make the db call synchronous and optimize it to be as fast as possible.

（吓人的）替代方法是使用cubbase的驱动程序并使用gevent之类的补丁对其进行修补，以创建您的自己的异步驱动程序。我不建议这样做。如果您真的想走这条路，请看看这个人对电机-他使mongo驱动程序异步。

The (scary) alternative is to take couchbase's driver and patch it with something like gevent to create your own async driver. I do not recommend doing this. If you really want to go down this route look at what this guy did with Motor - He made the mongo driver async.
