             Summary: Provide support for GraphFilter.vertexProperties()
                 Key: TINKERPOP-1403
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1403
             Project: TinkerPop
          Issue Type: Improvement
          Components: process, structure
    Affects Versions: 3.2.1
            Reporter: Marko A. Rodriguez
             Fix For: 3.3.0


[~rspitzer] stated that he is working with a graph that has millions of vertex properties on a vertex. If those properties are not needed for the traversal, then they should be filtered out.

Much like {{GraphFilter.edges()}}, we should add {{GraphFilter.vertexProperties(Traversal<Vertex,VertexProperty>)}}. That is, from the {{Vertex}} in question, traverse to those properties needed in the computation, where {{properties().limit(0)}} would be the push down predicate for "no properties." Another example, {{properties("income")}} would only provide income properties. Another example, {{properties("income").has("acl","public")}} would provide only those income properties that are public (according to access control).

--- SIDENOTE. In the docs we have {{bothE().limit(0)}} as the predicate for no edges. However, {{limit(0)}} by itself is sufficient. Likewise for {{GraphFilter.vertexProperties()}}.
