Hi there, I was planning to lay down my schema, Does Graph cool provides ability to make interfaces which could be implemented later on?

hey Rishabh 👋 this is one of the most common feature requests right now and we're already working on it 🙂 so stay tuned!

Can you provide me one date when you would lunch?

Unfortunately not. You can stay up to date by tracking the feature request here: https://github.com/graphcool/feature-requests/issues/83

Thanks
