Oracle already succeeded in tempting lots of people to look away from Java
as a language! Hopefully, the JVM is still a great runtime environment with
the best opensource professional projects.
Against that, Mr Ellison can't do much ;)
Give a try to Play framework + Java or Scala on JVM...

+1 to your approach :)
In Siena, I introduced the so-called aggregation which is entity group in
a more generic way.
It gives a very interesting way to design your models and fits lots of
situations!

You could use it from GAE even if the connection times will be quite longer

Hi Pascal,
You could access the underlying HttpServletRequest object in Play using:
Http.Request.current().args.get(ServletWrapper.SERVLET_REQ)
You should be able to call getUploadedBlobs on it.
Hope that helps.

yes you can but the free quota is much lower than before so you will reach
the limit much quicker...
but anyway, there is still the free edition!

No examples, just ideas till now :)
We should define a few usecases and look at the existing projects even in
SQL world!
Migration between DBs means 2 things IMO:
- An existing model evolves (rename field, change type of a field ...) -
this case is certainly the simplest in a first approach
-
My scripts are like your pseudo SQL commands but I would write those
commands in a DSL designed for our needs. Not SQL because SQL is not
functional and is quite limited in representing potential data
transformations.

In NoSQL, you don't have join as you said.
In NoSQL, managing data is more direct than RDBMS but when you want to merge
data from different tables, you need to do it yourself in your app. In a
summary, for relations, you do the job of the DB. So, this might seem a
drawback but it's also a big

Hi,
GAE+GWT works quite well!
If you find GWT a bit too heavy for your needs, you can also have a look at
the great lightweight Java framework Play! (http://www.playframework.org)
which brings a very nice efficient experience in developing web sites in
RAILS/iterative mode. It's really a huge
Not exactly the answer you expect certainly but wouldn't it better to
implement a Web/REST service somewhere in the same network as the Postgres
DB (if you can) which would just extract from Postgres and serve the data
you need from your GAE app?
Like that, you don't expose directly Postgres DB to
You can also give a try to Siena http://www.sienaproject.com
It provides the same level of features as Objectify just above Datastore.
But it's not specialized to GAE and aims at providing a bridge between NoSQL
DB (and also SQL DB when it's possible).
Currently we support GAE (sync/async) +

Hi,
BigTable is a NoSQL DB without join feature that you know in SQL.
So you manage relations manually and do join by issuing several request
instead a single one and you join within your application context.
Basically you do more computation in your app than in the DB in this case.
But the DB is

Nevertheless, it just lacks a backward aspect to the cursors ;)

From what I understand, I would answer no it shouldn't be indexed
