[appengine-java] Re: 1.2.5 memcache error
I have the same problem. I'm trying search in google, but i don't
found anything information over this topic.
My class cache is:

[appengine-java] Datanucleus site/resources
Sorry I send this here folks, but I've been trying to solve this in every other possible way and couldn't manage to access any of the Datanucleus guys.

Is there any particular reason for the Datanucleus site not being visible in some Southeastern Europe countries (e.g. Romania) ?

[appengine-java] Bulk delete behind RPC
Hi,
I'm trying to delete some unwanted data from my datastore and found
some code using the DatastoreService that I modified to delete as many
entries as possible in 10 seconds:
DatastoreService datastore =
DatastoreServiceFactory.getDatastoreService();
Query query = new Query(PostalCodes);
long starttime = (new Date()).getTime();
for (Entity entity : datastore.prepare(query).asIterable()) {
datastore.delete(entity.getKey());
if ((new Date().getTime()) (starttime + 1))
break;
}
It seems to work when I run this. I check the console's data viewer
and the Kind I'm trying to delete (PostalCodes) is gone, but the day
after I do this, the whole thing has been restored. Am I missing a
call to flush or commit or something?!?
Is there a better way to do this?
Thanks in advance,
Eric
=)

[appengine-java] Re: SimpleDS: an alternative for Datastore persistence
With JPA+RDBMS a relationship between two objects (say, Invoice and Customer) could be implemented by a customer attribute inside the Invoice class. In the RDBMS, this is translated to a CUSTOMER_ID column in the INVOICE table. Datanucleus does not support this (the relationship must be owned, that is, the Invoice class must be nested inside the Customer instance), otherwise you must do this by hand, managing the Key instance yourself (if I understood correctly). What I don't get is the rationale behind this. With DataNucleus (AccessPlatform) you have the full range of JDO and JPA relations for RDBMS, since it passes the TCKs for both, and would be impossible to do that if it didn't support something so basic. So in the situation you describe as not supported yes you do get a CUSTOMER_ID FK in the INVOICE table. This has been supported since the very first version of JPOX ... back in 2003. If instead you're talking about GAE/J specifics, as per the link that you provided, then that is a different issue ... dependent on Googles plugin for DataNucleus.

[appengine-java] Re: Time zones implementation is broken in Java AppEngine
Well, I don't know exactly how you implement your application. In my case, the users select their location by country/city and that location has a time zone ID associated with it. The ID is standard as defined in Java, say Asia/Jakarta is the time zone for Jakarta, Indonesia. As soon as they selected their location (which means the time zone too) I can set this time zone to any Calendar or DateFormat I use in my application and it works great - summer time is taken into account where it exists and so on. This is how it works on my machine where I have a proper Java implementation which knows exactly what Asia/Jakarta zone is. When I upload my application to the AppEngine however, Asia/Jakarta (and most other time zones defined in Java) becomes the same as GMT and all the finely crafted logic goes to hell... So in your case if you want your app to display time properly you need a way to find out where your user is coming from. One way is to find out from their IP address which isn't 100% reliable. Another way is to allow the users to make their choice. I follow the second option. You can see how it works (oh, well, doesn't work for most locations thanks to AppEngine's interpretation of Java) at http://lunarium.co.uk.

[appengine-java] Re: Bulk delete behind RPC
Hi Eric,
I'm trying to delete some unwanted data from my datastore and found
some code using the DatastoreService that I modified to delete as many
entries as possible in 10 seconds:
DatastoreService datastore =
DatastoreServiceFactory.getDatastoreService();
Query query = new Query(PostalCodes);
long starttime = (new Date()).getTime();
for (Entity entity : datastore.prepare(query).asIterable()) {
datastore.delete(entity.getKey());
if ((new Date().getTime()) (starttime + 1))
break;
}
Your code looks like no problem, I do not know the reason
the whole thing has been restored. It is unusual.
Regarding the performance, the following code is faster:
DatastoreService ds =
DatastoreServiceFactory.getDatastoreService();
Query query = new Query(PostalCodes);
query.setKeysOnly();
long starttime = (new Date()).getTime();
while (new Date().getTime() - starttime = 1) {
ListKey keys = new ArrayListKey();
for (Entity entity :
ds.prepare(query).asList(FetchOptions.Builder.withLimit(500))) {
keys.add(entity.getKey());
}
ds.delete(keys);
}
The points are setKeysOnly() and batch delete.
Hope this helps,
Yasuo Higa
