"High Replication" the recommended setup introduced about 8 Months
ago.
We switched a internal Application from a single Server hosted at
Rackspace to AppEngine.
Below you can see an analysis of a very expensive (->slow) internal
page.
We are testing from 12 Locations around the globe. See percentage of
requests which didn't
return success within 10 seconds:

And second: latency of that page:
http://static.23.nu/md/Pictures/latency_0985D51B.png
Can you tell what day we switched to AppEngine? It is an incredibly
useful product and I trust it much more than servers being run by
myself.
There are occasionally issues where you can't reprogram ("deploy") app
engine for a few hours. That is annoying. but user facing stability of
HR applications is great.

[google-appengine] Re: How to set 'timeout' I use urllib2.urlopen instead urlfetch?
HI Umm it was requested, but also for support for urllib2 took a while.

[google-appengine] How scalable is de data store?
Hi there, Everybody knows that the hardest task when scaling software is to scale the data (TPS). I was wondering how well AppEngine's datastore scales? What are the figures? - Petabytes of data? - Hundreds of thousands of transactions per second? - Full ACID support? - Low latency? The idea is to move, over time, all our data (and applications) into AppEngine. At the moment we have around 1 petabyte of "current" data, but it is growing fast. It would be desirable that we could have the same datastore to be used for Data mining. No more need for ETL and separated DBs. We want to simplify our enterprise architecture and minimize/ eliminate(??) all the internal integrations we have, so that we can find the current/consitent state of a customer or order in just (and only) one place. Is all that feasible now? Is there any use case for such volume? Cheers -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Index building - 24+ hours with small database
I have an application with two main entities (652 instances each) and a total entity count of 1351. One of my main entities (FileUnit) with 652 instances has just one index which is building for over 24 hours. This FileUnit is 20MB in size (really is just a blob with a key and a segment count which is generally 0 for all instances). The index is being created on the segment count. This application used to work just fine. I converted it to HRD recently and now I can not retrieve it as the index does not seem to build. This application accepts a special file from the users and stores it as a blob. Later, we process the blob and calculate statistics on the file. Right now is the date submission period and so we have 652 items (since 10/1/2011) and expect to be at 1200 by the end of October. So the usage is relatively low for a web application. What can be done to get the index to build ? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Integration tests with Robot framework and Google App engine - problem with async nature of GAE
Hi, all We are having problems with our integration tests of the app that runs on GAE. As you can see from the title, we are using Robot framework, Selenium server and all of that is nicely integrated with maven and runs on Jenkins. But, the problem is that our tests have a kind of non deterministic behavior. If I look a single test suite and run it several times (this stands both for local and app-spot environment) I can get various results. Tests can pass (which is expected) and they can fail - and every time they fail, there is no rule which one of them fails. This specific problem I am referring to emerges when testing storing objects into GAE. For that we are using Objectify library. As I understood from this post http://groups.google.com/group/objectify-appengine/browse_thread/thread/2395c585161a5274/997c916eecf00f38, GAE writes are pretty much async operations. So, Objectify gives us back an ID of newly persisted object which means it is persisted but when tests redirect us to the page showing the list of the objects, it can happen that newly persisted object is not in the list. My question would what do you do in these kind of situations? I know why this is happening and that this is not a bug but a feature, but we cannot accept this kind of behavior during testing. This way we are never sure if we broke something or everything is just fine, but GAE decided to be too async in the moment tests were running. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

Hi everyone, I need urgent help please. I'm new to eclipse, so please don't mind my question if it seems too trivial, I'm just in need for urgent help.

Select JSP File >>> Next. 3. Expand Guestbook directory and select war folder. Type in the filename (guestbook.jsp) >>> Next. 4. Select New JSP File (html). 5. Finish. Yet the problem persist, I have no idea why doesn't it work. When I tried to run the project, the IDE complains that "Errors exists in required project(s)."

[google-appengine] Billing stuck in "Leaving grace period"
Hi, I can't find any way to ask billing-specific questions so I'll just go ahead and ask here. A while ago a credit card payment for one of my company's apps bounced since we had forgotten to transfer money to the relevant account. After resolving this we attempted to pay our outstanding balance and re-add the same billing administrator again. This appeared to succeed, but ever since that (around two weeks ago), the application's billing has been stuck in a "leaving grace period" state and no money has been charged to our credit card. The app is active and there are no warnings about deactivating it, but the outstanding balance keeps increasing and we are currently not paying for the resources used. We'd really like to pay the outstanding balance, but the billing page doesn't seem to let us. The app id is "buffermonsters".

'', visited_profile_id: 2, visitor_id: 2}, {date_time: '',
visited_profile_id: 3, visitor_id: 2}]
But it seemed very RDMS.
I thought then about:
Profile
- visitors: [a collection of keys]
profile: { visitors: [1, 2, 3], name: "Thiago", bio: "...", id: 10 }
It seemed more reasonable. But in the frontend sometimes I need to list all
the profiles I've visited, sometimes all the users that visited mine. Should
I then do something like:
Profile
- visitors: [collection of keys] // the profiles that visited me
- visited: [collection of keys] // the profiles I visited
profile: { visitors: [1, 2, 3], visited: [11, 15], name: "Thiago", bio:
"...", id: 10 }
So at the end it's like my first idea.
What's the best way to do that?
Thank you for your help!
Thiago.

[google-appengine] Image Gurus: Reading and Modifying images pixels on google app engine
Hi all, hope someone can give us a hint!
We are stuck while transforming images on google app engine. We
basically want to achieve the following:
1) Generate a QRCode using google chartapi - DONE
2) Use urlfetch to get the qrcode just generated and use pngw/pngr
(image library for appengine) to read and modify the pixels on the
image - DONE
Now we have no idea how to:
3) save the modified image on a blobstore to then be able to show on
screen using blobstore api.
*we used the library locally and saving locally C:\\test.png works
just fine.
The code is below:
* We have used a pngr library which use InputStream for the PngReader
instead of File. It works App Engine for reading and modifying pixel
by pixel data from a PNG. http://github.com/jakeri/pngj-for-Google-App-Engine

Re: [google-appengine] Re: Too much contention on these datastore entities. please try again.
A further option involves using pull task queues. 1. Write a task to the pull queue for each item you wish to remember. 2. Have a queue reader run periodically - reading up to 1000 tasks at a time and writing the relevant information to the datastore. Although this sounds simple, you need to make sure that you run this doesn't run too often (and burn instance time with no benefit) or too infrequently (and fill up the queue because it never gets through all the tasks). Scaling is not done for you like it is with a push queue. Mat.

Re: [google-appengine] Integration tests with Robot framework and Google App engine - problem with async nature of GAE
This is the eventually-consistent nature of the HRD. On one hand, there is the argument that your users are going to see this same behavior so you should be coding your tests to accommodate it as well. On the other hand, maybe this isn't an issue for your users, just your tests. I'm not sure I would do this, but you can turn off the eventual nature of queries on the dev instance, making your tests run as if they're on the master/slave. There are instructions in the documentation. But if you go this route, make sure you *really* understand the consequences.

[google-appengine] Fwd: One-To-Many RElations Serialization
-- Forwarded message --
From: Bruno Sandivilli

Subject: Re: One-To-Many RElations Serialization
To: google-web-tool...@googlegroups.com
Thanks for the help from you guys!
But, yes im using IsSEriazeble. I've changed my code to detachable in both
classes, but, when i call:
if(listMyClass.size() > 0)
{
for (MyClass myClass : listMyClass) {
return (pm.detachCopy(myClass.getMyInnerClassList()));
}
}
return null;
gives me : The class "org.datanucleus.sco.backed.List" is not persistable.
This means that it either hasnt been enhanced, or that the enhanced version
of the file is not in the CLASSPATH (or is hidden by an unenhanced version),
or the Meta-Data/annotations for the class are not found.
debugging this, i've reached this : assertClassPersistable in the class
ObjectMAnagerImpl. This function :
public void assertClassPersistable(Class cls)
{
if (cls != null &&
!getOMFContext().getApiAdapter().isPersistable(cls) && !cls.isInterface())
{
throw new ClassNotPersistableException(cls.getName());
}
if (!hasPersistenceInformationForClass(cls))
{
throw new NoPersistenceInformationException(cls.getName());
}
}

Re: [google-appengine] GAE and SimpleDB via JPA
Hello, i'm lead dev of Siena, a lightweight ORM bridging SQL/NoSQL and we recently added support for SDB in it. You could use it from GAE even if the connection times will be quite longer than directly in EC2! Anyway it should work! http://www.sienaproject.com (not info on SDB because it's recent but if you're interested, don't hesitate to ask, I'll give the pointers to code samples) regards Pascal On Wed, Oct 5, 2011 at 6:14 PM, KotakeTetsuya wrote: > Hi > > Does anyone know if it's possible to use Amazons SimpleDB in the > Google App Engine in combination with the Java Persistence API? > > Kotake > > -- > You received this message because you are subscribed to the Google Groups > "Google App Engine" group. > To post to this group, send email to google-appengine@googlegroups.com. > To unsubscribe from this group, send email to > google-appengine+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/google-appengine?hl=en. > > -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] High error rate on programmatic blob creation
Hello all, I'm currently experiencing a really high error rate when trying to programatically create blobs - I'm on GAE/j (high replication) and getting deadlineexceeded exceptions on file.Open() on roughly every third call, this has been going on for a few hours. I'm using GAE as a synchronization back-end for a mobile app, so these failures aren't catastrophic - everything is done asyncronously in task queues which just retry on failure, but the failure rate is worrying. Not just the current spike that I'm experiencing, but the fact that in general I see this call fail at a much higher rate than other pieces of the service, including the datastore itself. I know that this is an experimental API, but I've had no choice in relying on it. The app prepares "deltas" for mobile clients so when they synchronize, they just have to download a pre-generated delta from the backend, and that delta has to be put into the blobstore as opposed to the datastore because it can be over a megabyte. Generally, when it works it works just fine, but I'm curious if anyone has any insights into why this API is so error-prone, if there's anything I can do about it, and whether I can expect some improvement here.
