AWS Lambda 任务在 6.00 秒后超时 [英] AWS Lambda Task timed out after 6.00 seconds

问题描述

我正在使用无服务器框架.我的 Lambda 函数连接到 DynamoDB 表以更新表中的项目.阅读与表的写入容量单位为5&自动缩放被禁用.AWS Lambda 函数分配了 128MB 内存.

I am using serverless framework. My Lambda function connects to DynamoDB table for updating item in table. Read & Write capacity units of table are 5 & auto_scaling is disabled. AWS Lambda function has 128MB memory allocated.

我使用 Jmeter 进行性能测试.我同时发送了 1000 个请求，一些响应给了我完美的输出，而另一些则给了内部服务器错误(502 Bad Gateway).我还分析了 cloudwatch 的日志，只得到任务超时错误.谁能建议我为什么会收到此错误以及如何解决?

推荐答案

使用无服务器框架时，AWS Lambda 函数的默认超时时间为 6 秒.只需将其更改为 文档 中所述的更高值:

The default timeout for AWS Lambda functions when using the Serverless framework is 6 seconds. Simply change that to a higher value as noted in the documentation:

functions:
  hello:
    ...
    timeout: 10 # optional, in seconds, default is 6
