以接口组件为例。如果每个流提供者都使用不同的接口，那么流就不是一种
标准的、普遍使用的事件驱动集成技术。在这种情况下，消费者软件的每个
开发人员都必须研究如何使用该特定接口并编写自定义代码来完成连接。更
糟糕的是，处理和路由事件流的核心基础设施不仅要知道这些不同的接口，
还要知道每个接口的不同版本。组合很快就会失控，并且想要集成到具有新
接口的新流中需要大量的开发和测试，因此成本非常高。综上所述，流集成
绝非商品。
我也从另一个角度得出了同样的结论。一开始我这样问道，当接口和协议发

也因此而演变。我还认识到这带来了新的可能性，我们将在稍后探讨。但图

过程中，我们拿到原始地图，并对其提出问题。沃德利在创建地图方法的早

从而轻松击败当时根深蒂固的老牌企业。
他的下一个问题是，他如何才能确保一个新的工具集不仅能从现有企业中获
