GAE使用数据存储服务与持久性管理器的赞成和反对
原标题:Pros and Cons of using DatastoreService vs PersistentManager for GAE

我正利用爪哇与GAE合作开发一个应用程序。 如果有人能解释使用Datastore Servicice 与持久性管理器进行数据存储访问的利弊, 我会非常感激。

谢谢!

问题回答

Datastore Service - 低水平 API. 持久性管理者(JDO) - 以数据存储服务为基础的高水平 API。

业绩:数据服务公司消耗的资源较少,长期管理公司(JDO)拥有一些间接费用。

发展:持续管理者的发展/支助速度要快得多。

另一个选项,其性能比 JDO 更快,开发速度比低水平 pipi - 目标化更快。这是新的有前途的技术。试一下。
