In 1, another problem is that I may not know the Keys of A and B at the

class Person {

class Group {
@Persistent(mappedBy = group)
ArrayListMembership memberships;
}
class Membership {
Key person;
Group group;
}
And what state are the objects in when you put them in the cache ? and
when you get them out ? JDOHelper.getObjectState(obj) tells you.
This is the role of a JDO L2 Cache as per

and you could easily use the javax.cache
My need is to implement database rowset paging behaviour.
i.e I want to create an Extent when session created and then on page

The problem:
JDOExtent is not serializable and hence the code below throws an
extent.
Please suggest an alternative
Why should a javax.jdo.Extent be Serializable ? JDO doesn't define it
to be so. Shouldn't be hard to put the objects of the Extent into a
List ...

Hi, here is introducing my JDO problem.
Is it issue of datanucleus or me?

2.invoke pm.getObjectById or iterate some query
I'm not sure if your taking of the problem is correct. To my mind it
runs:

is working for one company. Normalized version looks like:

Right, denormalization is promoted by the Max Ross video as in your

Why do you want an ORM exactly ? Object - Relational Mapping ? The
datastore is BigTable. It isn't an RDBMS.
GAE/J comes with JDO/JPA implementations for persistence to that
datastore.

I've been getting the same error, on what seems like the first request
since JVM-start/app-deployment.
It doesn't seem fatal, but does use some CPU time (1000-7000 cpu_ms,
where a typical request takes 100-200 cpu_ms), which is probably just
because the jvm/deployment is starting up.

It's my understanding that GAE doesn't support any gateways. It
supports URLFetch to communicate with external sites.
So if you can communicate with that provider via URLFetch, then you
are good to go, but you will of course have to write the code
