Answer 1

试试这个:

{
  "source": { "file": { "path": "/usr/share/orientdb-community-2.1.13/niloy_data/test.csv" } },
  "extractor": { "row": {} },
  "transformers": [
    { "csv": {} },
    {"vertex": {"class": "Names"} }
  ],
  "loader": {
    "orientdb": {
       "dbURL": "plocal:/usr/share/orientdb-community-2.1.13/databases/test",
       "dbType": "graph",
       "classes": [
         {"name": "Names","extends": "V"},
       ], "indexes": [
         {"class": "Names", "fields":["num:integer"], "type":"UNIQUE" }
       ]
    }
  }
}

这是结果:
