对象的定义 在C/C++中,对象就是堆(Heap)内存中的内存实体,从简单的基本数据类型(int,float,char)到聚合的数据类型(struct)一切皆为对象,我们说基本的数据类型是简单的对象(Simple Object),因为它仅包含数据属性。而struct级别的数据类型是完整的对象(Concrete Object),因为完整的对象具有属性和行为两个基本概念。 ...

在研究Flink的水位线(WaterMark)技术之前,我们可能需要Flink接收到流式数据,比如接入Kafka等。这就要求引入其他组件,增加了学习的难度。而Flink自身提供了datagen连接器,它可以用于生成流式数据,让问题内聚在Flink代码内部,从而降低学习探索的难度。 本节我们就介绍如何使用datagen生成数据。
