AWS Lambda - 如何在出现故障时停止重试 [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吗?我一直在阅读文档，但没有找到任何相关信息.

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

已编辑:现在可以更改 lambda 设置以禁用重试(请参阅 公告)

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

原答案:

没有办法禁用 Lambda 函数的重试行为.我建议两种选择来解决这个问题:

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

1. 使您的 Lambda 能够正确处理重试情况.您可以使用在重试 Lambda 时相同的 context.AwsRequestId(或相应字段).
2. 将您的 Lambda 放入状态机(使用 AWS Step Functions).您只能然后禁用重试.这篇博文我写的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.
