Mule流变量与会话变量性能

除了在Mulesoft页面中描述的流变量和会话变量之间的功能差异外，在使用这两个变量时，是否有任何显著的性能差异需要注意

---

对于我的项目，使用流和会话变量工作得非常好。因此，我需要决定使用哪个

当消息跨越传输边界时，会话变量会不断序列化和反序列化

但是，您是说您可以在项目中互换使用流或会话变量，因此这意味着您没有任何传输边界（否则您将丢失流变量）

在这种情况下，流和会话变量执行相同的操作：它们只是事件的属性

请注意，会话变量往往会通过HTTP端点泄漏，因此请小心使用它们。

Hi David，我仍然不清楚流变量和会话变量之间的区别。我添加了两个流作为示例，其中我初始化了两个变量，并且它们的行为方式相同，但是它们的存在跨越了传输屏障，您能澄清一下吗
