title: Is GraphQL stateless?
body: <p>Out of curiosity I start to read about GraphQL. Based on the samples on <a href="https://vinayaksb.wordpress.com/2016/03/15/why-need-to-choose-graphql-over-restodata-in-a-web-api-application-development-2/" rel="nofollow noreferrer">this article</a>, it looks like REST API request to me. Is it stateless? means it has no request, no response from the server? If yes, then how come it is more resource lighter than REST API?</p>
