Description

Hi,
Currently, VertexId is a type-synonym for Long. I would like to be able to use UUID as the vertex ID type because the data I want to process with GraphX uses that type for its primay-keys.
Given that the UUID is a unique identifier and its length is constant, why can not it be used?
