Async Lambda with Lambda Extensions

[metaskills]

Hi, I am the author of Lamby (https://lamby.custominktech.com) which is a Simple Rack adapter for AWS Lambda letting Rails work with API Gateway. I also have gem for ActiveJob called Lambdakiq (https://github.com/customink/lambdakiq). Was talking with another user of both on how to do async handler within Lambda for this GitHub Issue.

rails-lambda/lambdakiq#2

One idea I proposed is to use the new Lambda Extensions API (https://docs.aws.amazon.com/lambda/latest/dg/runtimes-extensions-api.html) which purports to run async from the handler. I've not dug into this too much and I am not sure if you can seen data to the Extension from the Runtime API... but thought I'd ask if y'all considered updating these docs https://docs.rollbar.com/docs/aws-lambda-ruby with something more async?
