-RocketMQ 消息模型如图1所示,主要由 Producer、Broker、Consumer 三部分组成,其中Producer 负责生产消息,Consumer 负责消费消息,Broker 负责存储消息。Broker 在实际部署过程中对应一台服务器,每个 Broker 可以存储多个Topic的消息,每个Topic的消息也可以分片存储于不同的 Broker。Message Queue 用于存储消息的物理地址,每个Topic中的消息地址存储于多个 Message Queue 中。ConsumerGroup 由多个Consumer 实例构成。

 ##  消息生产者(Producer)
  负责生产消息,一般由业务系统负责生产消息。一个消息生产者会把业务应用系统里产生的消息发送到broker服务器。RocketMQ提供多种发送方式,同步发送、异步发送、顺序发送、单向发送。同步和异步方式均需要Broker返回确认信息,单向发送不需要。
 ## 消息消费者(Consumer)
