This is just a suggestion that I would like to see implemented to the Twitch API to obtain data from large lists. So the idea is mainly for acquiring updated information from with subscriber and follower lists instead of making a request to obtain the full list over again. Developers could pass two timestamps and return data back that happened between the two. That way after developers obtain the full list for the first time they can keep track of when they last made a call to the server. Next time around, they can specify the data they want back from the last time they made the call instead of having to obtain the full list again.
Feel free to comment on what you think about this suggestion
