如何使用AWS Lambda接收无尽的WebSocket数据源? [英] How to receive an endless WebSocket data source using AWS Lambda?

问题描述

我想从WebSocket数据源中搜寻数据，通常WebSocket数据是一个无休止的流，而AWS Lambda函数有一个Timout限制，最大允许值为900秒.

I want to crawl data from a WebSocket data source, usually WebSocket data is an endless stream, while an AWS Lambda function has a Timout limit, the maximum allowed value is 900 seconds.

如果我的Lambda函数充当WebSocket客户端并连接到WebSocket网址(例如 wss://ws-feed-public.sandbox.pro.coinbase.com )，它将开始接收数据持续900秒，然后终止.

If my Lambda function acts as a WebSocket client and connects to a WebSocket url, e.g., wss://ws-feed-public.sandbox.pro.coinbase.com, it starts to receive data for 900 seconds and get terminated by then.

如何使我的Lamda函数永远运行?谢谢！

现在我正在Linux VM内运行搜寻器，是否可以将其迁移到AWS Lambda?

Right now I'm running my crawler inside a Linux VM, is it possible to migrate it to AWS Lambda?

推荐答案

AWS Lambda函数最多运行 900秒(15分钟).

AWS Lambda functions run for a maximum of 900 seconds (15 minutes).

没有办法扩展它.

您应继续使用Amazon EC2实例或容器(ECS，Fargate).

You should continue using an Amazon EC2 instance or a container (ECS, Fargate).

有趣的事实:最初发布时，限制为3分钟.后来延长到5分钟，然后延长到15分钟.

Fun fact: When initially released, the limit was 3 minutes. It was later extended to 5 minutes, then to 15 minutes.
