Request-Driven是希望执行某段业务逻辑。 Event-Driven则是事件驱动,事件在状态变更后触发,是业务逻辑执行完后导致的状态变更的通知。 日常我们使用的RPC服务都可以理解为是Request-Driven,都是请求执行某个命令;而日常使用的消息中间件都是Event-Driven。如果由Event来驱动执行逻辑,那么称为Event-Driven的应用。一个应用...
没有必要过分纠结一个应用是否是纯粹的Event-Driven的,更重要的是理解Event-Driven的思想,将它融入到架构的思想中来把业务系统做的更好。 什么是Event-Driven Architecture? Event-Driven Architecture是一种用于构建可扩展的分布式异步处理模式,由高度解耦的、单一职责的事件处理器组成。 Event-Driven Architecture模式有两...
Event-driven architecture (EDA) is a software design model built around the publication, capture, processing and storage of events.
EDA(Event-Driven Architecture)是一种实现组件之间松耦合、易扩展的架构方式。 一个最简单的EDA设计需要包含如下几个组件: Events:需要被处理的数据。 Event Handlers:处理Events的方式方法。 Event Loop:维护Events和Event Handlers之间的交互流程。 举个例子 : Event A将被Handler A处理,而Event B将被Handler B处...
1. What is an event-driven architecture At present, with the rise of microservices, the development of containerization technology, and the popularization of cloud-native and serverless concepts, event-driven has once again attracted widespread attention in the industry. ...
在微服务中使用领域事件 稍微回想一下计算机硬件的工作原理我们便不难发现,整个计算机的工作过程其实就是一个对事件的处理过程。当你点击鼠标、敲击键盘或者插上U盘时,计算机便以中断的形式处理各种外部事件。在软件开发领域,事件驱动架构(Event Driven Architecture,E

【转】EDA: Event-Driven Architecture事件驱动架构 SOA的核心是:暴露然后处理 expose and handle,SOA使事件Event跨系统流动 EDA是以事件为核心:什么时候触发 然后做什么。EDA是更加松散耦合,有极强的巨大事务处理能力 ESP—Event Stream Processing:监视事件数据流,分析这些事件。
Event-Driven Architecture Asynchronous messaging handles all inter-service communication. The exception is the communication from the BFF/UI layer to the downstream services. Sagas The same three sagas found inFTGOhave been implemented here in theorder-service. ...
Event sourcing - Event driven architecture If you are unfamiliar with these principles, we highly suggest diving deeper and understanding them before jumping into Dewdrop. It will make much more sense when you're familiar with these concepts. ...
