c# - AWS lambda : async C# handler

Question

AWS 文档指出

Using Async in C# Functions with AWS Lambda

If you know your Lambda function will require a long-running process, such as uploading large files to Amazon S3 or reading a large stream of records from DynamoDB, you can take advantage of the async/await pattern. By creating a handler with this signature, Lambda will execute the function synchronously and wait a maximum of 5 minutes for execution to complete before returning or timing out.

我觉得Lambda会很困惑

execute the function synchronously and wait a maximum of 5 minutes

当 Lambda 支持最多 15 分钟的处理时间时。这是否意味着如果我在处理程序上设置异步，我只能在 5 分钟内处理一个事件？

Answer 1

AWS support当时的最终回答:

• 文档不是最新的。它应该以最长 15 分钟的超时时间运行(取决于 Lambda 函数配置)
• async 修饰符不会改变 AWS 的行为方式，他们只会等待它。
• 行为差异仅在 .NET 方面
