调用多个AWS Lambda函数 [英] Invoke multiple aws lambda functions

问题描述

我们如何才能一个接一个地调用多个AWS Lambda函数?例如，如果一个AWS Lambda链由8个独立的lambda函数组成并且每个模拟一个1秒的处理事件，然后调用下一个函数在链中.

How can we invoke multiple AWS Lambda functions one after the other ?For example if an AWS Lambda chain consists of 8 separate lambda functions and each simulate a 1 sec processing event and then invoke the next function in the chain.

推荐答案

我不建议使用直接invoke启动功能.相反，您应该考虑创建SNS Topic并将Lambda函数订阅该主题.将消息发布到您的主题后，所有功能将同时启动.该解决方案也易于扩展.

I wouldn't recommend using direct invoke to launch your functions. Instead you should consider creating an SNS Topic and subscribing your Lambda functions to this topic. Once a message is published to your topic, all functions will fire at the same time. This solution is also easily scalable.

在官方文档中查看更多信息使用Amazon SNS调用Lambda函数通知
