------------------------------------
Summary: StarGraph shall drop edge properties when dropping edges
Key: TINKERPOP-2986
URL: https://issues.apache.org/jira/browse/TINKERPOP-2986
Project: TinkerPop
Issue Type: Improvement
Reporter: Boxuan Li
SparkGraphComputer uses StarGraph and StarGraph::StarVertex to represent
vertices and edges. The StarGraph::StarVertex::dropEdges method drops unneeded
edges, but it doesn't drop their edge properties, which are stored in another
data structure (StarGraph::edgeProperties).
In my use case, I only need edges with a certain label - yet all edge
properties are loaded and never get dropped. With my local fix, the memory
footprint drops by more than 90%.
