来自 CSV 日期时间的 OrientDB ETL

Question

这是我当前的配置文件

{
 "config": {
  "haltOnError": false
 },
 "source": {
  "file": {
   "path": "/home/user1/temp/real_user/user3.csv"
  }
 },
 "extractor": {
  "csv": {
   "columns": ["id", "name", "token", "username", "password", "created", "updated", "enabled", "is_admin", "is_banned", "userAvatar"],
   "columnsOnFirstLine": true
  },
  "field": {
   "fieldName": "created",
   "expression": "created.asDateTime()"
  }
 },
 "transformers": [{
  "vertex": {
   "class": "user"
  }
 }],
 "loader": {
  "orientdb": {
   "dbURL": "plocal:/home/user1/orientdb/real_user",
   "dbAutoCreateProperties": true,
   "dbType": "graph",
   "classes": [{
    "name": "user",
    "extends": "V"
   }],
   "indexes": [{
    "class": "user",
    "fields": ["id:long"],
    "type": "UNIQUE"
   }]
  }
 }
}

我的 csv 目前看起来像这样

我仍然想知道当我执行 ETL 时，orientdb 不会将我的日期时间识别为日期时间。

我尝试将数据类型放入列字段 "created:datetime"，但最终没有显示任何数据。

我想知道这种情况的正确解决方案是什么。

Answer 1

从下一个版本 2.2.8 开始，您将能够为日期和日期时间定义不同的默认模式：CSV extractor documentation

注意，定义列时，需要指定列的类型：

            "columns": ["id:string", "created:date", "updated:datetime"],

ETL模块2.2.8的snapshot jar可以和2.2.7一起使用没有问题:
