valueMap() is a really convenient step:
gremlin> g.V().has('person','name','marko').valueMap()
==>[name:[marko],age:[29]]
or perhaps more preferably:
gremlin> g.V().has('person','name','marko').valueMap('name','age')
==>[name:[marko],age:[29]]
but argh - multiproperties ruin everything. so then we're forced into
Gremlin acrobatics:
gremlin> g.V().has('name','marko').
......1> valueMap('name','age').
......2> unfold().
......3> group().
......4> by(keys).
......5> by(select(values).unfold())
==>[name:marko,age:29]
or as I usually recommend, use project():
gremlin>
g.V().has('person','name','marko').project('name','age').by('name').by('age')
==>[name:marko,age:29]
which is fine, but you pretty much have to type a lot more especially if
there are a lot of properties to contend with. What if we were to modulate
valueMap() with by(Traversal) so that:
g.V().has('person','name','marko').
valueMap('name','age').
by(unfold())
and the by() are just applied round-robin on the keys? Thoughts?
