I'm newbie in this App Engine. As far I know, lot of Django app
portability get solved if someone implement a Django database backend
for App Engine. Even I read "Once queryset-refactor lands in trunk, it
might also be possible to write a database backend for App Engine that
would allow any app to run properly. " at http://martyalchin.com/2008/apr/8/appengine/
Somebody can explain me why isn't implemented yet such database
backend? I, mean is a big deal? What are the main problems that ones
must address to write such backend? If the backend exist, porting
Django app will be more easy that using Google App Engine Helper for
Django?

Because the datastore is not a database. Some of their operations may
look similar, but they really are not. It is not a direct 1-to-1
mapping, no where near actually.

Traditional relational databases are not scalable, and using such
library would most likely result in a data organization that does not
scale well. Might be fine for a lot of apps, but it kind of defeat the
main purpose of using a cloud infrastructure.

web2py has a database abstraction layer that works with SQLIte, MySQL,
MSSQL, Oracle, DB2, Informix, Ingres, FireBird, MSSQL, and the Google
App Engine. It also does automatic migrations. You way want to look
into that.

I've started working on (or at least at this point only arguing with django
people) this project as well, but it is still some time off so I wouldn't
hold your breath quite yet.
