Support Response Streaming

[limcheekin]

Hi there,

Did the runtime interface client support streaming response as per announced?
https://aws.amazon.com/blogs/compute/introducing-aws-lambda-response-streaming/

If no, appreciate your sharing is there any near-term plan to work on it?

Thank you.

I'd like to see the streaming response in python too!!

With tools like LLM, the support is important. Else, it's not possible to use a lambda to return a stream of text.

@pprados aws-lambda-web-adapter enables response streaming from a python lambda.

I implemented an example: https://github.com/nicolasvo/ollama-lambda/tree/master/lambda (see Dockerfile.fastapi and
main.py).

However, this is done without lambda function handler. So if you need it, it might not be a solution.

@nicolasvo Thanks for sharing. Unfortunately I don't have time to look into it now as I'm working on higher priorities task.

I have a use case where I need to support response streaming within python lambdas. I currently rely on awslambdaric as the lambda runtime and am wondering if there are any plans to support response streaming before I try to look for another solution? Thanks in advance!
