如何在從appengine上傳到bigquery時忽略未知值

-1

我試圖將數據上傳到appengine中的bigquery。如何在從appengine上傳到bigquery時忽略未知值

這裏用我的代碼API從這個streaming sample

@Override 
    public void doPost(HttpServletRequest req, HttpServletResponse resp) throws IOException { 

    String projectId = "myprojectId"; 
    String datasetId = "mydatasetId"; 
    String tableId = "person"; 
    System.out.println("Enter JSON to stream to BigQuery: \n" + "Press End-of-stream (CTRL-D) to stop"); 

    String string = "[\n {\"Name\": \"test\", \"Age\": 0, \"Weight\": 100.0, \"IsMagic\": false},\n {\"Name\": \"test\", \"Age\": 1, \"Weight\": 100.0, \"IsMagic\": false},\n {\"Name\": \"test\", \"Age\": 2, \"Weight\": 100.0, \"IsMagic\": false},\n {\"Name\": \"test\", \"Age\": 3, \"Weight\": 100.0, \"IsMagic\": false},\n {\"Name\": \"test\", \"Age\": 0, \"Weight\": 100.0, \"IsMagic\": false}\n]"; 
    JsonReader jsonReader = new JsonReader(new StringReader(string)); 

    Iterator<TableDataInsertAllResponse> responses = StreamingSample.run(projectId, datasetId, tableId, jsonReader); 

    while (responses.hasNext()) { 
     log.info(responses.next()); 
    } 

    jsonReader.close(); 


}

現在我怎麼能做出大的查詢ignoreUnknownValues？有沒有我可以使用的圖書館？
