我可以限制对AWS Lambda的并发调用吗? [英] Can I limit concurrent invocations of an AWS Lambda?

问题描述

我有一个Lambda函数，该函数由P3到S3存储桶的触发.

I have a Lambda function that’s triggered by a PUT to an S3 bucket.

我想限制此Lambda函数，使其一次只能运行一个实例–我不希望两个实例同时运行.

I want to limit this Lambda function so that it’s only running one instance at a time – I don’t want two instances running concurrently.

我浏览了Lambda配置和文档，但看不到任何明显的内容.我可以编写自己的锁定系统，但是如果已经解决了这个问题，那就太好了.

I’ve had a look through the Lambda configuration and docs, but I can’t see anything obvious. I can about writing my own locking system, but it would be nice if this was already a solved problem.

如何限制Lambda的并发调用次数?

推荐答案

AWS Lambda现在支持单个函数的并发限制: https://aws.amazon.com/about-aws/whats-new/2017/11/set-concurrency-limits-on-individual-aws-lambda-functions/

AWS Lambda now supports concurrency limits on individual functions: https://aws.amazon.com/about-aws/whats-new/2017/11/set-concurrency-limits-on-individual-aws-lambda-functions/
