---------------------------------------------
Summary: 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: New Feature
Components: process, structure
Affects Versions: 3.0.0.GA
Reporter: Marko A. Rodriguez
It is important that reduce the size of the graph in OLAP so we can hold as
much in memory as possible and thus, increase 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}}.
