[jira] [Updated] (TINKERPOP-1346) Create custom ReferenceXXX
GryoSerializers
[ https://issues.apache.org/jira/browse/TINKERPOP-1346?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Marko A. Rodriguez updated TINKERPOP-1346:
------------------------------------------
Description:
Right now, to send a {{ReferenceEdge}} message, we serialize the form as:
{code}
KryoClassInteger[ReferenceEdge] + KryoClassObject[Edge ID] + KryoClassInteger[ReferenceVertex] + KryoClassObject[Vertex ID] + KryoClassInteger[ReferenceVertex] + KryoClassObject[Vertex ID]
{code}
Assuming {{Long}} Element ids, the math says:
{code}
48 bytes = 4 bytes + (4 bytes + 8 bytes [long]) + 4 bytes + (4 bytes + 8 bytes [long]) + 4 bytes + (4 bytes + 8 bytes [long])
{code}
We could get this smaller by not relying on Kryo's {{FieldSerializer}}.
{code}
KryoClassInteger[ReferenceEdge] + KryoClassInteger[VertexIDClass] + KryoClassObject[Edge ID] + KryoObject[Vertex ID] + KryoObject[Vertex ID]
{code}
The math says:
{code}
36 bytes = 4 bytes + 4 bytes + (4 bytes + 8 bytes [long]) + 8 bytes [long] + 8 bytes [long]
{code}
Similar techniques would apply to {{ReferenceVertexProperty}} and {{ReferenceProperty}}.
