I just received a link to a questionnaire from MDG and it says “How important is Meteor’s real-time data layer?”. But I don’t know what is Meteor’s real-time data layer.
- optimistic UI (actions are done both on the client and the server and undone if the server invalidates ?)
- reactivity (any change in data is automatically reflected in the client after rerendering ?)
- all of the above
- something else
