ETL腳本不創造邊緣

Question

我是OrientDb的新手，但有一個問題和ETL腳本，我只是不知道爲什麼它不起作用。這是該方案：

CSV文件：

PersonName,PersonAge,CarMake,CarAge 
John,23,Nissan,3 
Peter,45,Mini,25 
Paul,23,Morgan,15 
Jim,24,Mini,24 

的ETL JSON如下：

{ 
    "config": {"log": "INFO", 
    "fileDirectory": "/Users/johnbrogan/Downloads/orientdb-community-2.2.20/import/", 
    "fileName": "SimpleTest.csv", 
    "dbDirectory": "plocal:/Users/johnbrogan/Downloads/orientdb-community-2.2.20/databases/", 
    "dbName": "simpleTest", 
    "parallel": false 
    }, 
    "begin": [ 
    {"let": {"name": "$filePath", "expression": "$fileDirectory.append($fileName)"}}, 
    {"let": {"name": "$dbPath", "expression": "$dbDirectory.append($dbName)"}} 
    ], 
    "source": { "file": { "path": "$filePath", "lock": true } 
    }, 
    "extractor": { 
     "csv": {} 
    }, 
    "transformers": [{ 

    "vertex": { "class": "Person", "skipDuplicates": true}, 
    "edge": { 
     "unresolvedLinkAction": "CREATE", 
     "class": "hasCar", 
     "joinFieldName": "CarMake", 
     "lookup": "Car.CarMake" 
    } 
    }], 
    "loader": { 
    "orientdb": { 
     "dbURL": "$dbPath", 
     "dbType": "graph", 
     "batchCommit": 1000, 
     "dbAutoCreate": true, 
     "dbAutoDropIfExists": true, 
     "standardElementConstraints": false, 
     "classes": [ 
     {"name": "Person", "extends": "V"}, 
     {"name": "Car", "extends": "V"}, 
     {"name": "hasCar", "extends": "E"} 
     ], 
     "indexes": [ 
     {"class":"Person", "fields":["PersonName:string"], "type":"UNIQUE" }, 
     {"class":"Car", "fields":["CarMake:string"], "type":"UNIQUE" } 
     ] 
    } 
    } 
} 

腳本沒有警告和沒有錯誤運行。類和索引的創建與4 x Person記錄一樣，但Car記錄和hasCar邊不會創建。

在終端上的輸出是：

它看起來像邊緣變換沒有運行，任何想法，爲什麼？

回答我自己的問題，爲任何其他Orientdb新手有類似問題的好處。這僅僅是一個不夠的{}案例。每個變壓器需要按照以下方式分配在他們自己的一套{}中
