partitioned vertex labels different ids in edges

I created a partitioned vertex label and added 2 vertices. Then I connected them with 2 edges.

This is what I got

> gremlin> g.V()
> ==>v[4226]
> ==>v[8202]
> gremlin> g.E()
> ==>e[ody54-38q-1lh-6ei][4202-follows->8298]
> ==>e[eb-6fu-1lh-3a2][8346-follows->4250]

As you can see the in and out vertex ids for edges are different from the original vertex ids.

Is this the supposed behavior? Can this be added to the docs?

Also are partitioned vertex labels stable enough to use in production?

Start with the partitioned vertex-label behavior shown by the Gremlin g.V() and g.E() queries, and review the existing JanusGraph documentation for partitioned vertex labels. Document whether the differing edge endpoint IDs are expected and address the question about production stability.
