QA:

Question: Can we stream from an AWS lambda function?

Answer: No, unfortunately. Streaming results is not supported in AWS javascript lambda functions (yet). (I have heard that is supported only in Java labda functions). One of the possible workarounds is: upload the resulting zipped stream back to s3 bucket and redirect the client to it.
