Hi,
would it be a good idea to keep an member variable with an httpClient.
With that would be not neccessary to create a new DefaultHttpClient
each time data is posted? Think of a use case in which data is posted
or getted in intervalls...

There are no post-deploy hooks, but you can probably wrap the deploy script

Ok. So I've changed the entities to use entity.setUnindexedProperty().
To get rid of the superfluous the indices I'm doing something like
this:
Query q = new Query(PlayerSnapshot.class.getName());
ListEntity asList =
ds.prepare(q).asList(FetchOptions.Builder.withLimit(n).offset(o));
You can solve it in GAE just like anywhere else. Store the password
(or token) in the client, send it with the request and / or sign the
request somehow, and validate the request server side. Nothing really
special about GAE in this respect.

There is really nothing to prefetch in this case. Author.posts is
