如果此标志为false，客户机状态就在连接代理过程中保持不变；例如，客户应用程序无需每次在后续的重连接时都重新订阅。
If this flag is false, the client state remains in place across connections with the broker; for example, the client application does not need to re-subscribe every time it subsequently reconnects.

In addition, in the same study, all patients were evaluated with dobutamine stress echo, which was negative in all; IMA levels were unchanged at baseline, peak stress and 1 hour after stress.31.
所以只要你坚持并发编程的最简单规则——无状态服务和不变对象，将你的服务绑定到任何生产者或消费者上都会轻而易举。
