Django Channel layers -- 实时应用程序的消息中间件

Channel Layers

==============

Channel layers允许您在应用程序的不同实例之间进行对话。如果您不想在数据库中交换所有消息或事件，它们是制作分布式实时应用程序的有用部分。

此外，它们还可以与工作进程结合使用，以创建基本任务队列或卸载任务-请参阅工作进程和后台任务中的更多内容。:doc:/topics/worker.

… note::

Channel layers are an entirely optional part of Channels. If you don’t want
to use them, just leave CHANNEL_LAYERS unset, or set it to the empty
dict {}.

… warning::

Channel layers have a purely async interface (for both send and receive);
you will need to wrap them in a converter if you want to call them from
synchronous code (see below).
