Hey Max,
Took a heap dump using two different scenarios. In test 1, I set the -
Xmx to 100M, and in test 2 I set the max to 512M, and am comparing the
difference between the number of objects across the two memory
scenarios. In my code, I'm running a for-loop that executes 5000
times, and most
I get this issue pretty often too, although my experience is that you
likely have an issue with one of your entities (sometimes your entity
can be properly coded, but there could be a fluke with how DataNucleus
+GAE interpret a particular feature/annotation, especially with
JPA).
For example, I
you're bumping into. Have you tried taking a heap
dump to see what exactly is building up?

Hi Wesley,
Thanks for the heads up. Any reason an empty-String cannot be used
for a Link? I was coding defensively by making all Link object
default to an empty String (since in order to do anything with them I
need to constantly be calling the getValue() function on the Link).
Now, I have to

I responded directly to your email with out app-id. Any ideas?

You could setup a cron job to hit a servlet every minute to keep your

so much traffic that new instances need to spawn up for scaling

I've been testing out Spring Security 3.0 combined with RPX from
Janrain. Basically I can authenticate via Google, Facebook, Twitter,

Works great (although startup is a bit slower than normal due to

Kind of an involved question, but I'm wondering if it's possible to
use the parent-key pattern with JPA to search for N child entities
of a given parent that have a particular property. I can get this to
work if I include the parent object in my child entity, but I'd like
it to work when I just

I'm running some JUnit tests to excercise my data-layer classes using
the TestEnvironment patter implementing ApiProxy.Environment (i.e., so
I can test my code's datastore operations inside of JUnit).
The tests run fine, except when I try to interact with the Statistics

Sorry for not clarifying -- my example is all JPA, and the import
statements in my code imply the following:

@javax.persistence.Embedded

Hmm...looks like I'm not using @MappedSuperclass in my abstract parent
class. I'll give that a try and see if it fixes things.

Bump.
I'm running into this same exact problem -- I have the same type of
entity setup, and am do a key-only query on a non-root object. Also
getting the same exact Illegal argument error. I get the error
whether I'm running in a transaction or not (which is strange -- I
have my property
datanucleus.appengine.autoCreateDatastoreTxns to).
So, given that this is a simple keys-only query scenario (i.e., no
entity manipulation or updating is going on), why is the DataNucleus/
JPA code trying to make some updates to entity Date fields (thus
triggering a transaction exception)?
Thoughts?

In other threads on this forum I've read that the Datastore can handle
between 1 and 10 Writes per Second for an Entity (or Entity Group).
I'm wondering if there's a similar bottleneck for reads-ueries in the
datastore. Does anyone know what the max number of Reads I should
expect is?
