Thank you for your response. Sorry, I&#x27;m still not getting it. Not even talking about big data, what I mean is a very simple database application, say with 10k documents in a document based storage model. Now let&#x27;s say I want to show a list view and a sum over one of the fields in those documents. You&#x27;d probably agree that this is a typical usecase for a productivity app. Now how would I do this in the sandstorm model?
