[jira] [Created] (TINKERPOP3-609) Reduce the memory footprint of Gryo

Marko A. Rodriguez created TINKERPOP3-609:
---------------------------------------------

             Summary: Reduce the memory footprint of Gryo
                 Key: TINKERPOP3-609
                 URL: https://issues.apache.org/jira/browse/TINKERPOP3-609
             Project: TinkerPop 3
          Issue Type: Improvement
          Components: io
    Affects Versions: 3.0.0.GA
            Reporter: Marko A. Rodriguez
            Assignee: stephen mallette
            Priority: Critical


A 1 million vertex graph with 1 edge each is a 150meg file. That is 150 bytes per vertex/edge.

If the vertex id is a long that is 4 bytes.
If the edge id is a long that is 4 bytes.
The edge should only have ONE id for the otherV of 4 bytes.
The edge label should be somehow "enum'd" and 1 byte.
The vertex label should be somehow "enum'd" and 1 byte.
Add 2-3 bytes for terminators.

Thus, we should be able to get away with a 17 byte representation (assuming no variable width encodings) and thus, a 17 meg file. That is a near 10x file size reduction.
