I think the potential for dgraph is really awesome. After doing a survey of various graph databases, they seem to be well positioned for one that has the ability to scale horizontally. This is not something many of the others have. From what I can tell the others require a single write master.

My only gripe with it so far is their documentation could use some updating. The onboarding path isn't real straight forward. I've had to jump around to different parts of the documentation and piece together stuff to get started.
