Yes you are right. I've been misleaded by the fact that, from my point of view, there is a bug in the documentation : The configuration shows as you write : China - 1 US - 2 Europe - 3 And the picture in "Multiple servers per cluster" part shows what I wrote : China - 3 US -

Hi, I'm a bit not agree. Graph api is based on documents too. So graph vertexes and edges may be used through object api. Of course, edges will not be mapped into objects (as references), but I think its a pro and not con: you can operate with properties through objects and always have very lig

Ricardo beat me to it. SailsJS differs from meteor as it's server side only. This can be seen as an advantage (decoupled from the client means you can choose whatever client framework you prefer) or disadvantage (need to use 2 frameworks). To bridge that there are projects like angular-sails
