The forums for AWS are good to solve problems @jarvinenemil. Lambda + Clojure is very slow to start without a keepalive timer to keep hot. APIGateway + clojure routing is iffy at times. I'd love to read a good resource on that. The readme for lein-aws gateway has a decent amount of API Gateway json info in it: https://github.com/trieloff/lein-aws-apigateway

I mean https://github.com/jpb/ring-aws-lambda-adapter is the one with the good example of AWS API gateway + json.
