Oleg, for an example of this, see http://docs.neo4j.org/chunked/snapshot/gremlin-plugin.html#rest-api-send-a-gremlin-script---json-encoded-with-table-resultswhere the returned table does not contain nodes or relationships, but only properties, this resulting in _MUCH_ smaller return values, doing most of the work on the server.
Is that what you are looking for?
