             Summary: why GraphX vertexId should be Long ?
                 Key: SPARK-25932
                 URL: https://issues.apache.org/jira/browse/SPARK-25932
             Project: Spark
          Issue Type: Question
          Components: GraphX
    Affects Versions: 2.3.2
            Reporter: Ali Zadedehbalaei
             Fix For: 2.3.2


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?
