---------------------------------------
Resolution: Won't Do
Confirmed with [~bryncooke] that this isn't a worry anymore
> Unrolling of collection for ids
> -------------------------------
>
> Key: TINKERPOP-1345
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1345
> Project: TinkerPop
> Issue Type: Bug
> Components: process
> Affects Versions: 3.2.0-incubating
> Reporter: Matthias Broecheler
> Priority: Major
>
> In GraphStep, TinkerPop does this:
> {code}
> this.ids = (ids.length == 1 && ids[0] instanceof Collection) ? ((Collection)
> ids[0]).toArray(new Object[((Collection) ids[0]).size()]) : ids;
> {code}
> which means that collections are automatically unrolled when there is only
> one element. This breaks TP implementations that use collections to represent
> ids, for instance, because their id representation has multiple components
> (like a primary key in an RDMBS).
