[英]Synchronizing Google App Engine DataStore with local instance via Datanucleus REST API or some other Java API

I'd like to know if someone can guide me in this aspect, as everything I know is that Datanucleus REST API may help into making the contents of my local Google App Engine datastore and the online one the same, but there might be also another way to do that which is easier, as I'm having great difficulties to understand how could might be done via that API. 我想知道是否有人可以在这方面指导我，因为我所知道的就是Datanucleus REST API可能有助于使本地Google App Engine数据存储区和在线存储区的内容相同，但是可能还有另一个这样做更容易，因为我很难理解如何通过该API进行操作。 Application has been done in Java so there's no point in trying to develop it into phyton know, it's way too late for that now. 应用程序已经用Java完成，因此试图将其开发为phyton毫无意义，现在还为时已晚。

Thanks a lot for your interest. 非常感谢您的关注。

Edit: Well I actually found some interesting tools here: http://www.appwrench.onpositive.com , but it would be better for my application if I could done by code as it would need to be executed automatically once a day, so if you know of some not too hard way to achieve what I'm telling I'll be grateful if you tell me so, if not I'll just stick with the tools. 编辑：好吧，我实际上在这里找到了一些有趣的工具： http : //www.appwrench.onpositive.com ，但是如果我可以用代码完成，那对我的应用程序会更好，因为它需要每天自动执行一次，所以如果您知道实现我要告诉的目标的一些不太困难的方法，如果您这样告诉我，我将不胜感激；否则，我会坚持使用这些工具。

I don't know DataNucleus, but you can connect GAE Datastore from local machines using Remote API 我不知道DataNucleus，但是您可以使用Remote API从本地计算机连接GAE Datastore

you can use Remote API to access a production datastore from an app running on your local machine . 您可以使用远程API 从本地计算机上运行的应用访问生产数据存储 。 You can also use Remote API to access the datastore of one App Engine app from a different App Engine app. 您还可以使用远程API从另一个App Engine应用程序访问一个App Engine应用程序的数据存储。

With this, you can code an app to synchronize the data 这样，您可以编写一个应用程序来同步数据
