Query:
g.withSack(0).V().hasLabel('A').has('label_A','A').union(__.emit().repeat(sack(sum).by(constant(1)).in()),emit().repeat(sack(sum).by(constant(-1)).out())).project('level','properties').by(sack()).by(tree().by(valueMap().by(unfold())).unfold())
Output:
{
"level": 1,
"properties": {
"key": {
"label_A": "A"
},
"value": {
"{label_A=A}": {}
}
}
},
{
"level": 2,
"properties": {
"key": {
"label_A": "A"
},
"value": {
"{label_A=A}": {}
}
}
}
}
Getting keys in json format but not values. Please suggest changes in query to acheive the values in json format.
The tree()
step returns a tree structure in the form of a Map
of Map
instances essentially so the output is about what you can expect. In this case, I wonder if you need to use tree()
and could instead get by with path()
as it seems like it accomplishes the same result without the added structure:
g.withSack(0).
V().hasLabel('A').has('label_A','A').
union(__.emit().repeat(sack(sum).by(constant(1)).in()),
emit().repeat(sack(sum).by(constant(-1)).out())).
project('level','properties').
by(sack()).
by(path().by(elementMap()))
