> OLAP {{dedup()}} is highly inefficient when it's fed with non elements.
> In a customer project a query similar tho the following returned a result in slightly more than 6 seconds:
> {noformat}
> persistedRDD.
> V().hasLabel("label1","label2").
> inE("edgeLabel1","edgeLabel2").outV().
> id().count()
> {noformat}
> The same query with {{dedup()}} added:
> {noformat}
> persistedRDD.
> V().hasLabel("label1","label2").
> inE("edgeLabel1","edgeLabel2").outV().
> id().dedup().count()
> {noformat}
> ...took more than 120 seconds.
