AWS Lambda-发生故障时如何停止重试 [英] AWS Lambda - How to stop retries when there is a failure

问题描述

我知道，当Lambda函数失败时(例如，超时)，它会尝试再次运行该函数3次.有什么办法可以避免这种行为?我一直在阅读文档，但没有发现任何有关此的信息.

I know that when a Lambda function fails (for example when there is a time out), it tries to run the function 3 more times again. Is there any way to avoid this behavior? I' have been reading the documentation, but didn't find anyting about this.

谢谢！

推荐答案

编辑:现在可以更改lambda设置以禁用重试(请参见

EDITED: It's now possible to change the lambda settings to disable retries (see announcement)

原始答案:

无法禁用Lambda函数的重试行为. 我建议有两种解决方法:

There isn't a way to disable retry behavior of Lambda functions. I suggest two options to deal with that:

1. 使Lambda能够正确处理重试案例.您可以使用context.AwsRequestId(或相应的字段)，当重试Lambda时，它将是相同的.
2. 将Lambda放入状态机中(使用AWS Step Functions).然后，您只能禁用重试. 此博客文章书面给出了更一般的解释.

1. Make your Lambda able to handle retry cases correctly. You can use context.AwsRequestId (or corresponding field) that will be the same when a Lambda is retried.
2. Put your Lambda inside a state machine (using AWS Step Functions). You can only then disable retries. This blog post I've written gives a more general explanation.
