It is supported in appengine. Every time you set a property in an
Entity (appengine Entity) you can specify if that property is indexed
or not. The partial indexing support just lets you control that on a
per instance basis instead of having the field always indexed or not.

Yes, I think it is 10. You can delete old versions so you can upload
new ones, but you can only have a limited number at a time.

There was recent discussion about dependencies (valid for Objectify or any
datastore based impl.) but the eclipse plugin question has not been
answered well.

I appreciate your concern for Objectify staying clean, and consistent.
It *is* good to have frameworks that offer different feature sets and
ways in which they implement them.

Okay, time to chime in. There are some pretty different philosophies
driving these frameworks.

As I understand it, you never need (or can) prefix you appid to the
key. If you could it would open up the option to get data from other
appids, and that is not possible. That is also a huge security hole,
if it existed :(

It is very simple to know if you need to use google apps or not.
Here is the article about it:

accounts)

I got a read error when I tried running with my existing (v1.3.0)
data-store file; I created a new one (by renaming the old one) and
restarting. I suspect the internal format is different and the old
format cannot be read. Whether this is by design or a bug is another
question.

If you would like a very simple interface to the app engine datastore
(not JPA/JDO) then Objectify might be for you. It doesn't sound like
you need to use JDO/JPA. Here is an example of exactly what you want:

To summarize the issue, you cannot search for a null (list) if you
store a null value in any instance of that (list) property. This is
due to the way indexing is done for lists/arrays in the datastore.
The short answer is no. You will have to store another property as a
marker that you have a null

You can try the getTail(int) method but I don't think that will do
what you want. It is a destructive operation and will cost you
bandwidth and time.

The docs here seem to indicate that dequeuing happens at 5/sec
(default and 10 max).
