---------------------------------------------
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()}}.
