使用Spring Cloud Stream处理一次是否可以获得准确的处理? [英] Is it possible to get exactly once processing with Spring Cloud Stream?

问题描述

当前，我正在使用具有几乎默认配置的SCS在微服务之间发送和接收消息. 不知何故我已经读过了

Currently I'm using SCS with almost default configuration for sending and receiving message between microservices. Somehow I've read this

并想知道我们是否只是通过Spring启动应用程序中的属性在其中放置值为"exactly-once"的"processing.guarantee"属性，是否可行?

and wonder that it is gonna works or not if we just put the property called "processing.guarantee" with value "exactly-once" there through properties in Spring boot application ?

推荐答案

在您的问题上下文中，您应该将Spring Cloud Stream视为目标系统(例如，Kafka)和您的代码之间的委托.启用这种委派的绑定程序通常以传播目标系统支持的任何功能的方式实现.

In the context of your question you should look at Spring Cloud Stream as just a delegate between target system (e.g., Kafka) and your code. The binders that enable such delegation are usually implemented in such way that they propagate whatever functionality supported by the target system.
