[jira] [Created] (TINKERPOP-2973) GraphComputer should allow vertex properties filtering

Boxuan Li created TINKERPOP-2973:
------------------------------------

             Summary: GraphComputer should allow vertex properties filtering
                 Key: TINKERPOP-2973
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-2973
             Project: TinkerPop
          Issue Type: New Feature
            Reporter: Boxuan Li
         Attachments: image-2023-07-25-22-48-37-510.png, image-2023-07-25-22-49-16-418.png

GraphComputer has vertexFilter and edgeFilter, but not yet a filter for vertex properties. Many vertex programs don't need many if not all vertex properties. PageRank, for example, does not need any vertex properties at all. Having a vertex property filter can reduce memory/disk usage.

 

I implemented a vertex property filter and will submit a PR soon. In my use case, the RDD size reduces from 2.8GB to 2.1GB by applying a vertex property filter.
