理解stateful computation有状态计算

  • Overview

    Streaming computation can be either stateless or stateful.

    A stateless program looks at each individual event and creates some output based on that last event;

    A stateful program creates output based on multiple events taken together.

    stateful 用于定义computation,是对“计算”这个功能的分类。
