Hi,
I deleted a large number of objects from the datastore that I din't
required (around 7000 of them).
Each of those objects had a blob associated with it, referenced by a
String (blob key).
As you might have guessed by now, I forgot to delete those blobs.
Now I don't have any reference to them,
Hi all

I have made some changes in the class file, whose objects were
persisted... Now I need to empty the local datastore. Is there a way?

in my application a servlet stores the user's details when she starts
with the application as follows
User user=new User();
HttpSession session=req.getSession();
user.setUser(userName);
user.setRole("user");
session.setAttribute("user", user);
RequestDispatcher rd=req.getRequestDispatcher("/HomeP
GAE performs best for simultaneous read operations. So there could be
virtually any no.
of users reading at the same time, no issue. But when it comes to
making updates
performance degradation is significant.
To get a better understanding of how gae performs under heavy load, I
recommend

That is probably because you stay in a different timezone than the
server's.

common... gae does not interfere with your jsp or servlet output.
any javascript will work. i am using analytics code and a lot of other
javascript.
only explanation i can give is that you deployed to the wrong version,
or something
like that.

I understand that the remote_api module is only available for python
for now,
but is it possible to use python's remote_api to manipulate datastore
used
by a java application?
Since remote_api uses lowest level api and datastore is app
independent this
seems to be feasible.
Has anyone tried this?

I agree. I often find myself changing my Class structure just to be
able to run efficiently on Datastore.
It's not like that I mind optimizing my code. It's just that in the
past in the past 3 days I have spent only 10% time in writing the
program logic and 90% in wondering how to read and write e

Try this :
Query query = pm.newQuery(YourThing.class);
query.setRange(0,300);
List< YourThing > results = (List< YourThing >) query.execute();
Iterator iter = results.iterator();
while(iter.hasNext()){
YourThing p = (YourThing)iter.next();
The JSP page I created is using too much of CPU and showing high
latency.
The page lists all the entities of type Person.class. (At present
there are 43 entities in the datastore.)
(Person is a root entity)
Following is the method to return the list of all Person objects in
the datastore :-
pub
Opps! got it.
Key k = KeyFactory.createKey(Person.class.getSimpleName(),
String.valueOf(fullName.hashCode()));
instead of
Key k = KeyFactory.createKey(Person.class.getSimpleName(),
fullName.hashCode());

Code:

fullName.hashCode());
p.setKey(k);
