Marko A. Rodriguez updated TINKERPOP3-613:
------------------------------------------
Fix Version/s: 3.0.0.GA
> Create StarGraph as a micro "TinkerGraph"-style POJO graph.
> -----------------------------------------------------------
>
> Key: TINKERPOP3-613
> URL: https://issues.apache.org/jira/browse/TINKERPOP3-613
> Project: TinkerPop 3
> Issue Type: Improvement
> Components: process, structure
> Reporter: Marko A. Rodriguez
> Fix For: 3.0.0.GA
>
>
> It is important that reduce the size of the graph in OLAP so we can hold as
> much in memory as possible and thus, decrease compute times. In order to
> reduce the serialization cost, we have the following ticket TINKERPOP3-609.
> This ticket is about reducing the in-memory footprint. Right now we use
> TinkerGraph as the "star graph" for TinkerGraphComputer, GiraphGraphComputer,
> and SparkGraphComputer. While TinkerGraph is small, it could be smaller.
> We should introduce {{StarGraph}} that provides the following benefits over
> {{TinkerGraph}}
> * A {{StarEdge}} only has the adjacent vertex id.
> * All labels are enum'd by some short number-based HashMap.
> * {{StarElements}} should not maintain a reference back to Graph (i.e.
> {{.graph()}}).
> * The graph should only have a set of vertices, not edges.
> * The above vertex set should be a bloom filter.
> * There will be no indices in {{StarGraph}}.
> * Removing one edge will automatically drop all edges (for fast MapReduce
> prep).
