App Engine Datastore access

Is it possible to query App Engine's Datastore from outside the cloud, i.e. a client application?

I could possibly write an app to be housed within AppStore and query the Datastore returning XML-formatted data; I want to know, however, if there are any Datastore endpoints which would allow me to do it directly.

Also, in case it is possible, am I able to do so via SSL?

+3 A:

There's no reason you couldn't create your own app engine application that exposes the datastore as a web service (either http or https). In fact, here is a link to a python version.

Thanks, Taylor - yet, in case I do not want to write a module myself, I believe Nick's answer more closely resembles what I was searching for - it's already written!

+2 A:

Yes. The remote_api library supports exactly this use-case. If you're using Java, there's a Java remote_api handler available, and the client will be available at some point in the future.

You can use this over SSL in the same way as any other handler.

Thanks Nick, I guess your answer most closely resembles what I expected. Yet, let me make sure I am getting things right: this is a module which I "install", and which provides a RESTful endpoint for other applications to directly query the Datastore, right? (meaning there are no "out-of-the-box" interfaces for directly querying the Datastore from outside the cloud)Thanks for your clarification!

It's a module you install, but it's not really 'restful', and it's intended only for administrative access - anyone who can use remote_api basically has complete control over your app's data. And it's about as out of the box as it comes - it's part of the SDK, you just need to install a handler to use it.
