I'm wondering if it is possible to print the rids of vertices's created during the oetl.sh script, I felt it might help in faster creation of Edges from Java code.
You can use for example
"transformers": [
{ "vertex": { "class": "yourVertex" } },
{ "code": { "language": "Javascript", "code": "print('Current record: ' + record.getIdentity());" } }
],
Hope it helps.
