使用 java 云函数写入 bigquery

我想创建一个表，然后使用云函数写入BigQuery，但我不想复制表中的数据，所以我首先删除了表，然后在每次调用该函数时创建表.

    public static void runCreateTable() {
        Schema schema =
                Schema.of(
                        Field.of("id", StandardSQLTypeName.INT64),
                        Field.of("name", StandardSQLTypeName.STRING));
        createTable(DATASET, TABLE_NAME, schema);
    }

public static void createTable(String datasetName, String tableName, Schema schema) {
        try {
            BigQuery bigquery = BigQueryOptions.getDefaultInstance().getService();
            TableId tableId = TableId.of(datasetName, tableName);
            TableDefinition tableDefinition = StandardTableDefinition.of(schema);
            TableInfo tableInfo = TableInfo.newBuilder(tableId, tableDefinition).build();
            bigquery.create(tableInfo);
            System.out.println("Table created successfully");
        } catch (BigQueryException e) {
            System.out.println("Table was not created. \n" + e.toString());
        }
    }

BigQuery bigquery = BigQueryOptions.getDefaultInstance().getService();

            if (bigquery.getTable(TableId.of(DATASET, TABLE_NAME)).delete()) {
                runCreateTable();
                TableRow row = new TableRow();

                for (Map.Entry<String, Object> entry : campaign.entrySet()) {
                    row.set("id", entry.getKey()).set("name", entry.getValue());
                    bigquery.insertAll(InsertAllRequest.newBuilder(bigquery.getTable(TableId.of(DATASET, TABLE_NAME))).addRow(row).build());
                }
            }
