我们使用称为disposable actors的模式:

• 为每个申请请求创建一个新的临时参与者.
• 该参与者可能会创建其他参与者来执行与请求相关的某些工作.
• 处理后的结果发送回客户端.
• 与此请求有关的所有临时演员都被杀死.那就是使用PoisonPill的地方.

• A new temporary actor is created for each application request.
• This actor may create some other actors to do some work related to the request.
• Processed result is sent back to client.
• All temporary actors related to this request are killed. That's the place where PoisonPill is used.

创建一个actor意味着非常低的开销(大约300个字节的RAM)，因此这是一个很好的实践.

Creating an actor implies a very low overhead (about 300 bytes of RAM), so it's quite a good practise.
