[appengine-java] Is endsWith(String) not supported in org.datanucleus.store.appengine.query.DatastoreQuery
When I make a query of type:
SELECT FROM Business WHERE url.endsWith('google.com')
I get the following exception:
[java] org.datanucleus.store.appengine.query.DatastoreQuery
$UnsupportedData
storeFeatureException: Problem with query SELECT FROM Business WHERE
url.endsWith('google.com'): Unsupported method endsWith while pa
rsing expression: InvokeExpression{[PrimaryExpression{url}].endsWith
(Literal{google.com})}
Is endsWith(String) not supported?
Seemed like the documentation was saying otherwise:
http://www.datanucleus.org/products/accessplatform/jdo/jdoql_methods.html
Am I missing something?
Thanks!

[appengine-java] Re: First Request High CPU
I believe that, in normal situations, App Engine shuts down your application if it has not had any request for the last 10 minutes. You could set your cron to run it every five, and it should be good. I however do not understand how your (Ikai) cron could take up so much CPU use. I'd profile that.

I don't mind enabling billing and don't even mind any $ value (as a consequence), but I would like to know if the problem will go away... Does anybody else know the answer for this question? Thanks On Nov 30 2009, 11:38 am, Ikai L (Google) ika...@google.com wrote: Yes. This is an issue we are working on. Basically, what happens is that instances of your application are elastic and loaded up upon demand. As your application grows, we will grow with you, but one of the consequences of this is that if your application is not receiving many requests, we may cycle you out to allocate more instances for an application with higher resource requirements. We discourage running cron jobs to reduce startup time because ultimately, this will result in more aggressive cycling for all of our users. We're looking at several techniques to speed up Java application startup time. It's also been suggested that we should look at a billing enabled option for keeping a certain number of instances warm at all times. On Sun, Nov 29, 2009 at 11:22 PM, Jeffrey Goetsch jeffg@gmail.comwrote: I have noticed that the first request to a server instance has really high CPU usage (7000+ milliseconds). After the server is up, the same request takes only 20 milliseconds. I am not using Spring or any other framework. It appears that the time is used during the first execute call on a Datastore query. Is this a normal behavior? I have a cron job that I was running every 2 minutes, but that alone was using 15% of my free quota. I have moved the cron to every minute, and I'm seeing huge improvement on performance and quota. The cron used to take 7000+ ms and now I am getting 20ms.

But next time when I fetched parent from memcache, *child* is again null. Why? I noticed that this happens only if I detach parent, if I don't, *child* survives.

[appengine-java] Re: app engine urlfetch without new heap allocation every time you set a new url
Are you sure you are getting bad performance out of calling new too many times? I would be interested to see benchmarks showing the performance. The JVM is very smart, worrying about using a new vs not is usually is a losing battle. Brian Goetz has some good presentations on this topic I have attended, and 99% of the time trying to be smart and write fast code (by not using new(), etc.) gave me code that ran the same or slower than the more readable version of the code. On a side note, a URL fetch is an external request, very likely taking 100-500ms. Making a new object is a few cycles of the processor. I think you are optimizing at the wrong level, if you can cache the results of your URL fetch you could have 1x the performance of avoiding calls to new.

In my case it'd be particularly helpful because the String representation's natural sort order matches the sort order of the class itself, so it'd be indexable.

Re: [appengine-java] Persist/query test.test1.Test and test.test2.Test
By default the kind of the datastore entity is derived from the simple name
of the class, and test.test1.Test.class.getSimpleName() is the same as
test.test2.Test.class.getSimpleName(). This is documented here:
http://code.google.com/appengine/docs/java/datastore/dataclasses.html#Class_and_Field_Annotations
If you need to persist two classes in different packages but with the same
name you can override the kind like this:
@PersistenceCapable(table = SomethingElse)
public class Test {
// ...
}
Hope this helps,

[appengine-java] Re: Low Level API type conversion?
Ok, this was just me being lame.

Re: [google-appengine] Re: Best way to model relations
Hi again,
thanks a lot for your answers.
So it looks like developing for GAE is quite a different paradigm...
From your answers i understand that:
1. I should precompute and store all aggregated data I might need
2. Changes to my database are NOT immediate (hence I can't expect accuracy)
I will consider this from now on.
Thanks again!

A few additional notes:
1. If you need an accurate reference count number, you need to put the
routine (which reads the Photo entity, increment the reference count,
and put it back to the database) into a transaction, but it is
relatively expensive. I usually don't put it in a transaction unless I
absolutely need an accurate number.
2. Making too many put() calls in one HTTP request is not a good idea.
I'd suggest to perform non critical operations (such as incrementing
reference count) asynchronously using Task Queue.

First of all, please remember that GAE/database is an Object-database,
not a Relational-database. You can design your database with
relations, but you will likely hit a roadblock later if you heavily
rely on relations (because of the lack of JOIN and the performance
problem of nested queries).
If I were you, I would simply create two models (Artist and Photo),
and have the artist property on Photo class, which is just a
reference to an Artist entity (ReferenceProperty). If you want to
show all the Photos done by a particular Artist, you just need to
query it (Photos.all().filter('artist', ...)).
Alternatively, you could specify the Artist entity as the parent
entity of each Photo, which essentially creates an entity group for
each Artist - which has pros (transactions) and cons (possible
performance hit because of transactions).
Third alternative is ListProperty, but this is difficult to do it
right without putting them in an entity group (which is alternative
two)...

Looks like an exciting platform to develop on, but there're many

I used to develop in PHP/MySQL, and I quite don't get how should I
proceed in order to get an efficient relational model.
To simplify things, I have two kind of entities: Artist and Photo. I
need to define relations one-to-many between instances of these two
entities. That is, an Artist can have many Photos, and a Photo can
only have one Artist.
In my table-shaped mind, I would model three kinds of entities
(Artist, Photo, ArtistPhotoRelation). Would this approach be the
right
thing in GAE/datastore? Maybe I should avoid the relational entity,
and use multiple-valued properties in the Artist instead?

[google-appengine] Issue storing image in blob property, then retrieving
Hi there, I'm just running into an issue trying to store an image in a blob property, and trying to load it afterwards. The process is as follows: 1. My front-end (a Flash application) sends the data to be stored to GAE (i'm using pyamf) 2. The remote function stores the data (I save the image in a blob property) and replies back (success/error) 3. The Flash application receives the result, and if ok, tries to load the image I just saved. This works perfectly locally (local GAE development environment), but when running it online I get an Error 500 on step 3, as if the image was never saved. Next time I try to load the same image, it works. So am I running some kind of delay-related issue here? Of course I tried waitting a couple of seconds (even a minute) before attempting to load the saved images, but didn't work either. Does anyone know what may be happening here?

[google-appengine] OverQuotaError, but I have a huge allowance?
I am having problems when running an application I've built.

The user is saved and afterwards a welcome email is sent out.

[google-appengine] Advanced query performance issue
Hello everyone. I am trying to figure out a way so support an advanced search need that we have using JDO in Google Apps. Here is the scenario: Imagine we have a Doctor object as follows: Doctor Key Name List of specialties (could be a list of strings) Location (to keep it simple city and state) Suppose we have 20,000 doctors in the database, and my user needs to be able to do advanced searches based on specialty and location at the same time, including all or including any of the specified. E.g.: - All doctors specialized in neurology and oncology in the Chicago or Milwaukee area - All doctors specialized in cardiology or neurology or physiotherapy in Aurora Note: I only need to return the first 1000 that match the search. I have tried a few different approaches but none had a satisfactory performance* and supported all scenarios * By satisfactory performance I mean measuring only the query, under one second. I would really appreciate any input. Thanks! -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: How to test my application with local database
Hello ivanceras, YOUR PROPERTY datanucleus.ConnectionURL - I do not know what your dev environment is. I use NetBeans; this has a connection set up to use my local MySQL database. I noticed an extra // between the jdbc: and mysql parts of your connection URL. But you might need this for your environment. You might want to verify your value for this property. YOUR PROPERTY datanucleus.storeManagerType I personally do not use this property. As you will probably know, the relevant DataNucleus documentation describes this property as: 'Type of the StoreManager to use for this PMF/EMF. This has typical values of rdbms, db4o. If it isn't specified then it falls back to trying to find the StoreManager from the connection URL. The associated DataNucleus plugin has to be in the CLASSPATH when selecting this. When using data sources (as usually done in a JavaEE container), DataNucleus cannot find out the correct type automatically and this option must be set.' I assume that your set-up requires this property (otherwise I would suggest omitting it as I do). All I can suggest here is to verify that you have the relevant DataNucleus plug-in and that it can be found from your class path. I do not speak from experience about this property since I have never used it. Don't make the mistake I have made: ensure that you use the same DataNucleus plug-in version number as is used by the version of GAE that you use!

[google-appengine] PersistenceManager multiple instances
I'm having some difficulty with the PersistenceManager class. When running my app locally, it appears I can have multiple PersistenceManagers open at once operating on different entity groups at the same time. However, when I try to do this in a JUnit test, I end up getting all sorts of exceptions. It stands to reason that it should be okay opening up multiple PersistenceManagers, but my unit tests beg to differ. In this case, what's wrong, my code or the unit test? Would it be better, too, if I provided a testcase as to what's going on? Thanks in advance. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

datanucleus-rdbms?, datanucleus-db4o?), and consider setting the
persistence property datanucleus.storeManagerType to the type of
store you are using e.g rdbms, db4o
at org.datanucleus.store.FederationManager.initialiseStoreManager
(FederationManager.java:197)
at org.datanucleus.store.FederationManager.init
(FederationManager.java:70)
at org.datanucleus.ObjectManagerFactoryImpl.initialiseStoreManager
(ObjectManagerFactoryImpl.java:153)
at
org.datanucleus.jdo.JDOPersistenceManagerFactory.freezeConfiguration
(JDOPersistenceManagerFactory.java:526)
... 51 more
Here is my PMF.java class. I guess there are still more configurations
to make. I created the database jdo. I guess there will be no need to
create a table?
public final class PMF {
private static final PersistenceManagerFactory pmfInstance =
JDOHelper.getPersistenceManagerFactory(mysql);
//JDOHelper.getPersistenceManagerFactory(postgresql);
//JDOHelper.getPersistenceManagerFactory(transactions-
optional);
private PMF() {}
public static PersistenceManagerFactory get() {
return pmfInstance;
}
}
Hope someone could help me with this.
Thanks,
ivanceras

Hello ivanceras,
YOUR PROPERTY datanucleus.ConnectionURL
-
I do not know what your dev environment is. I use NetBeans; this has a
connection set up to use my local MySQL database. I noticed an extra
// between the jdbc: and mysql parts of your connection URL. But
you might need this for your environment. You might want to verify
your value for this property.
YOUR PROPERTY datanucleus.storeManagerType
I personally do not use this property. As you will probably know, the
relevant DataNucleus documentation describes this property as:
'Type of the StoreManager to use for this PMF/EMF. This has typical
values of rdbms, db4o. If it isn't specified then it falls back to
trying to find the StoreManager from the connection URL. The
associated DataNucleus plugin has to be in the CLASSPATH when
selecting this. When using data sources (as usually done in a JavaEE
container), DataNucleus cannot find out the correct type automatically
and this option must be set.'
I assume that your set-up requires this property (otherwise I would
suggest omitting it as I do). All I can suggest here is to verify that
you have the relevant DataNucleus plug-in and that it can be found
from your class path. I do not speak from experience about this
property since I have never used it.
Don't make the mistake I have made: ensure that you use the same
DataNucleus plug-in version number as is used by the version of GAE
that you use!
Cheers,
Ian

[google-appengine] auto run tasks using dev sdk
I've read some articles on auto running tasks using the developer sdk and python. The articles I've found don't provide a good workaround. I am POSTing tasks using the Task class with parameters. I would like to run concurrent background tasks on my dev machine. If I can only run them single threaded, I guess that's OK for now. What type of shell script or equivalent should I write that will automatically run tasks by first discovering them in the queues and then submitting them as POSTs to the appropriate queue URLs with the original parameters? Note: The GAE SDK is running on OS X. -- You received this message because you are subscribed to the Google Groups Google App Engine group.
