-------------------------------------------
Summary: Global dedup() in reducing by() of group() detaches
elements for OLTP
Key: TINKERPOP-2529
URL: https://issues.apache.org/jira/browse/TINKERPOP-2529
Project: TinkerPop
Issue Type: Bug
Components: process
Affects Versions: 3.4.10
Reporter: Stephen Mallette
Assignee: Stephen Mallette
When elements are detached they are not re-attached and thus prevent anything
following `group()` from traversing them. For example:
{code}
g.V().both().
group().by().by(out().dedup().fold()).
unfold().
select(Column.values).
unfold().
out()
{code}
When {{dedup()}} detaches the later attempt to traverse {{out()}} will produce
no output as there are no edges on a detached object. I think we need to keep
detachment in place for OLAP sake where I think this approach was envisioned.
