Nicholas Tietz commented on SPARK-1153:
---------------------------------------
We are also running into this issue and would like this feature. For our use
case and our data size, even a low risk of hash collisions is not acceptable,
so we have to have a reliable way to form unique ids from our current unique
string ids.
I'm going to work on a patch next week.
Since this is marked "won't fix" due to inactivity, what's the process if a PR
is submitted? (Sorry, new to the Apache contribution process.)
> Generalize VertexId in GraphX so that UUIDs can be used as vertex IDs.

> Key: SPARK-1153
> URL: https://issues.apache.org/jira/browse/SPARK-1153
> Project: Spark
> Issue Type: Improvement
> Components: GraphX
> Affects Versions: 0.9.0
> Reporter: Deepak Nulu
>
> 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. Others might have a different
> type for their primary-keys. Generalizing {{VertexId}} (with a type class)
> will help in such cases.
