Why is polling used?

Isn't it possible to subscribe to push notification without the need of polling S3 for updates?
S3 notifications can go to SNS, which can be consumed by something server-side. This is updating entirely on the client-side.
To update the client side properly would require a websocket for each client, something Lambda doesn't support as it has a max 5 minute operating window.
@pas256 I was intrigued by this idea too.
BTW I've just come across your project, glad I did because I was just about to code it myself!
I had a nearly-identitical architecture in mind, differing only by storing messages in SQS. Which may not be a good idea if your chat supports >2 chatters (mine doesn't).
I've seen references to SQS supporting long-polling JS clients, such as here: https://github.com/lg/lambda-job
Just a thought!
Nice. I didn't know about that project. Thanks.
