--------------------------------------
Resolution: Won't Do
Assignee: (was: Marko A. Rodriguez)
Since 3.0.2....if we haven't worried about it yet I doubt we're worried about
that contract now.
> How should OLAP treat Collection<Element> objects? No contract is specified.

> Key: TINKERPOP-831
> URL: https://issues.apache.org/jira/browse/TINKERPOP-831
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.0.2-incubating
> Reporter: Marko A. Rodriguez
> Priority: Major
> Labels: breaking
>
> Assume the following OLAP query:
> {code}
> g.V.group.by(label).by().by(order(local).by('name'))
> {code}
> The {{Map<String,List<Vertex>>}} that is processed by {{GroupMapReduce}}
> doesn't have "real vertices." For TinkerGraph/Spark/Giraph, we use
> {{DetachedVertices}}. However, we don't have a specification for forcing this
> on vendors. ........ We need a contract so its not "who knows?! -- pura vida
> -- namaste -- comme ci, comme ça"
