Ask HN: Good discussion about designing an sdk for RESTful services?

So I have a Restful service that allows users to build basic data pipelines on the fly and kick off jobs on really huge datasets so a user needs to poll the API in order to figure out whether her actions committed successfully.

Now I'm trying to wrap this around a Python SDK. I was wondering if there is any discussion on building a good SDK for non-trivial REST services, something like AWS SDK for example.
