有用的事务协议需要以某种方式隐藏故障的所有恢复案例，或者在协议中或者在参与者中，并且协议可以启用。
A useful transactional protocol requires that all the recovery cases for failure be covered in some way, either in the protocol or in the participants, and be enabled by the protocol.
除了设定超时，没有其他方式能检测这种故障。超时一般是指组件不能定期发送心跳消息或不能响应请求。
There is no way to detect the failure except by timeout: it either stops sending "I'm alive" (heartbeat) messages or fails to respond to requests.
除了正在记录的功能故障和已发送的警报外，也可以同样的方式监控并修改性能延迟。
In addition to function failures being logged and alerts sent, performance delays can also be monitored and alerted in the same way.
