Marko A. Rodriguez updated TINKERPOP3-320:
------------------------------------------
Description:
This is another trivial "bulker" that is vendor agnostic. For any {{Graph}}
that provides a {{GraphComputer}}, {{BulkDumpingMapReduce}} is executed as such:
{code}
g.compute().mapReduce(BulkDumpingMapReduce.build().output('dir/').writer(GraphSONWriter.class).create()).submit()
{code}
The implementation is:
{code}
public BulkDumpingMapReduce implements MapReduce {
public void map(vertex, emitter) {
StringBufferThingy vertexString = new StringBufferThingy()
graphSONWriter.write(vertex,stringBufferStreamThingy);
emitter.emit(vertexString.toString());
}
}
{code}
NOTES:
* MapReduce generates a key/value pair result set. Thus,
{{MapReduce.generateResult()}} would need to clip off the key and write the
value to the output location.
