> 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?
