[appengine-java] BlobstoreService has dependency on HttpServletRequest, my web framework does not
My web framework doesn't give access to the raw servlet request or response objects (stateless). This is obviously making it rather difficult to use the BlobstoreService. Is there any way to get the BlobKeys from a successful upload other than BlobstoreService.getUploadedBlobs? I suppose I could bounce the request off another server using servlets for handling but this is awfully hacky. On the flip side, can I use ByteArrayInputStream to fetch a blob and write it directly to a response without actually calling blobstoreService.serve? I know this isn't efficient, but I do not see a way to get a raw url to the blob meaning I can't access the store from a different server. It's looking like I will have to setup another GAE app to handle file uploads. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Entity relationship designing - best practice
i want to hear the best practice on establishing entity relationships in my
case-
Example, for sake of discussion:-
User
Exam
Page
Question
Answer
As you can see, from top, each entity has 1 - many relationship with entity
immediately beneath it.
Interesting case is a User can have any number of Exam and it can *scale* in
whatever manner, but a Exam usually will have few Pages,
a Page with few Questions, Questions with few Answers
I saw this interesting post
best practice to persist medium-large
datahttp://www.mail-archive.com/google-appengine-java@googlegroups.com/msg06087.html
(which is also a answer to this ques) and it made me to design like this:
Also i plan to keep each entity in its own entity group, as recommended by
AppEngine - totally eliminating Parent relationship, as far as possible
class User{
String name;
// ListKeyExam exams; NOT a good idea, as this will unnecessarily load
bulk amt of Exam keys when i load User
...
}
So i would use a query to get all Exams created by any User. Fine. But
class Exam{
String subject;
// With this i can *quickly* retrieve all Pages with keys, but as Exam and
Page are not in same Entity Group,
// how do i maintain *consistency* when, say, i delete a Page and
accordingly remove that Key entry in Exam.
// Also as said earlier, no. of pages (hence keys) shouldn't be too high, so
dont need to worry abt size
ListKeyPage pages;
}
class Page{
String pageNo.
KeyExam exam; // with this i can *only(?)* use query to get all Pages
under a Exam, so *unnecessary index scan*[1]
ListKeyQuestion questions;
}
The same extends to Page - Question - Answer
[1] Retrieving via Keys are faster than
queryinghttp://www.mail-archive.com/google-appengine@googlegroups.com/msg33846.html
So what is your recommendation and why?
I can suspect that it should be a trade-off between unnecessary loading of
keys/extra scan of indices but want to get some thoughts and what about
consistency?
Thanks much in advance.
p.s. though not relevant, most likely i will use low level framework, mainly
Objectify..

Re: [appengine-java] Re: Not sending email with Javamail and no error
Straight zero utilizations means the email api is not accepting your
requests rather than the message getting lost in transit.
Where the error goes is not obvious due to Issue 1800
I suggest continuing to replace your fields with static values to see which
one is not accepted.
My gut says to check the character set - UTF-8 works fine for me.
Otherwise you may be encountering a known issue with the mail server:

Re: [appengine-java] Re: The API call mail.Send() required more quota than is available.
8 is fairly arbitrary, but there's always going to be a number that bothers people, be it 10, 20 or 50. You should enable billing. We only charge if you go above the daily free quota, and it raises the rate limit.

[google-appengine] Re: This request used a high amount of CPU and may soon exceed its quota - 2010/2011
Are you sure about this ? I have noticed that I did indeed get new additional instance, but are their automatic scaling algorithm so simple that uses only average latency time. Maybe this is truth for first 10 instances and then they add additional checking. Although they nowhere display average cpu_ms or api_cpu_ms per instance we can't be sure that they don't collect it and use it. Few bytes per instance and few mathematical operation. I would collect it. With low latency they are able to easily scale applications on application servers, but with high cpu/api cpu ms they are not able to easily scale datastore or any other api service. So we can't say that 160 ms request with 17000 cpu ms is nice scalable request, but is 160 ms request with 1700 cpu ms ok or not. So is there some good max cpu/api cpu policy that they didn't explained ? Or they did with this yellow and red coloring schema around 700/1000 ms cpu usage. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] C2DM Rate Limiting
Hey all, We're running into an odd issue, and not sure if it's us, the AppEngine group, or the C2DM Android group at Google so I thought I'd post here to start and see where we can get. We have implemented a C2DM server on AppEngine servicing several hundred of our clients' Android applications, sending a lot of messages. It was working quite well for a while, but now we're seeing a lot of Error=QuotaExceeded returns from the C2DM server. Seems like one of three causes: -Our back-off algorithms aren't correct. Hard to tell though as the google docs are very light on what's an acceptable rate: http://code.google.com/android/c2dm/index.html I have turned off all retry logic, only sending original messages and it still triggers, so guessing it's not a back-off problem. -We're just plain hitting a C2DM limit, but would be great to be able to talk to someone at Google-Android about raising it. -Google is limited based on source IP and lumping all GAE requests together in a DDoS prevention bucket. Which would mean that over time our ability to send messages from GAE would only become worse. At this point I'm just looking to eliminate possibilities and the third one there seems to be the easiest to rule out. Does anyone on the AppEngine team have insight into whether that might be what's happening?

[google-appengine] App Engine Limit on Index Entries per Entity
I know that there is a limit of 5000 index entries per entity, which means I can't do things like this: class Foo(db.Model): x = db.ListProperty(int) y = db.ListProperty(int) foo1 = Foo(x = range(5001)) foo1.put() Furthermore, if I have the index in index.yaml - kind: Foo properties: - name: x - name: y then I also see from this thread: http://groups.google.com/group/google-appengine/browse_thread/thread/d5f4dcb7d00ed4c6 that I can't do this: foo2 = Foo(x = range(100), y=range(100)) foo2.put() because that would give me 10,000 index entries. However, my question is: if I DON'T have any entries in index.yaml for Foo and try: foo3 = Foo(x = range(100), y=range(100)) foo3.put() will that still raise the BadRequestError:Too many indexed properties for entity exception? From my tests, it looks like it won't cause any errors. Is this correct? How many index entries would foo3 have in this case? Is it 200 (the sum of the lengths of each list)?

[google-appengine] Re: Memcache broken with Always On?
Hit Erik, From your stack trace, I think you are seeing something else. Have you got an explicit serialVersionUID set in the com.WikiHop.jdo.Pi class (your key is OK I think) that you are putting into Memcache? And if so has it changed at some point? It looks like you may be either trying to read out a different class entirely than was inserted into the cache, or have changed or added the serialVersionUID in the value class since an entry was inserted and it is now stale. serialVersionUID is a way of identifying a class (or version of a class) to the java serialization framework - if you change it you are telling it that it is effectively no longer compatible for serialization with previous instances, even if you have change nothing else in the class.

I have a django app that is hosted in google app engine. I would like to have usernames in subdomains to show a personal page for a user in my app. Like this: *username*.*example.com* I know how to get the username from the url and work on it on my app but i don't know how to setup the cnames on godaddy for it. Right now the cnames are: *Host* - *Points to* www - ghs.google.com #it redirects to the app on appengine mail - ghs.google.com #it redirects to the mail service for my domain I want that every subdomain goes to CNAME *www* and keep the CNAME for mail. I have tried: *Host* - *Points to* www - ghs.google.com mail - ghs.google.com * - www but godaddy does not allow me to save HOST with * it tells me that it is not a valid host.

[google-appengine] Re: Channel API CPU usage
Right now my only application using the Channel API only use it for a few minutes at a time. Also, I recall from the Google presentation on Channel API one of the selling points was that it wouldn't use our application quota for the constant polling. Charging for two hours up-front rather defeats that. We may as well use a custom long-polling solution or one of the 3rd- party push APIs (pusher, beacon, etc) since it would be cheaper, and the 3rd-party APIs have more features (like shared channels). My point is, if you want to see any sort of wide-spread adoption of this API, you're going to need to solve this somehow. On Dec 11, 7:37 pm, Moishe mois...@google.com wrote: Assuming that a channel setup costs 2.77 seconds, having just 10,000 active users setup 4 channels per day would cost $92.30 per month. That's not counting any CPU costs for actually sending messages. At that rate, I can't really use the channel API as much as I'd like and I have to look at alternatives such as Beacon now that I know how cool this technology is. Better docs on Channel API quota use are coming, but the reason the CPU charge is so high is that the CreateChannel charges up-front for 2 hours of connect time by clients. It is true that if you have the same user connecting repeatedly for a short time but spread out over periods of time longer than two hours (obviously degenerate case would be connecting for a couple of minutes every two hours and one second), the charge will be high. One thing I'm looking at is the ability to create a token that expires after an application-specified period, if your application's usage patterns warrant it. Note that you can store the token for re-use in eg. a cookie so you don't need to regenerate it more frequently than every two hours. Sending a message doesn't charge any CPU time at all (since the connection's already established), just outbound bandwidth. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Static files cached even after update with changes
Hi Noel, People often want static content cached -- it reduces the load on your app. Also, there might be other intermediate caches to worry about too, so it may not be only Google caching your content. Yes, you should use some type of cache busting strategy. It depends on how your iPhone app is implemented, but perhaps you can use a version number on your assets so they can be changed between versions?

I suggest you always use UTF-8, not windows-1256.
However, if you insist on using windows-1256, you should encode your

self.response.out.write(u'some unicode string'.*encode*('windows-1256'))
or:

If I remember right, think the coloring scheme is left over from when there were other quotas in place.

I have noticed that I did indeed get new additional instance, but are their automatic scaling algorithm so simple that uses only average latency time. Maybe this is truth for first 10 instances and then they add additional checking. Although they nowhere display average cpu_ms or api_cpu_ms per instance we can't be sure that they don't collect it and use it. Few bytes per instance and few mathematical operation. I would collect it. With low latency they are able to easily scale applications on application servers, but with high cpu/api cpu ms they are not able to easily scale datastore or any other api service. So we can't say that 160 ms request with 17000 cpu ms is nice scalable request, but is 160 ms request with 1700 cpu ms ok or not. So is there some good max cpu/api cpu policy that they didn't explained ? Or they did with this yellow and red coloring schema around 700/1000 ms cpu usage. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Documentation on AppEngine's caching reverse proxy
The biggest undocumented features of the edge cache we've had to deal with is that it does not honor the Vary header, and that it is turned on when you enable billing for an app. I agree, however, that regardless of what details are posted in this group, the edge cache behavior should be documented in the official docs. -Mike -=- On Dec 17, 9:31 am, Ikai Lan (Google) ikai.l+gro...@google.com wrote: App Engine's edge cache is not guaranteed. It's best effort caching, caching that any ISP downstream could also have implemented.

Re: [google-appengine] Re: This request used a high amount of CPU and may soon exceed its quota - 2010/2011
Yes, I remember this. But after removal of 'high cpu quota' there was no (spoken) penalty for over 1000 ms request latency (beside bad user UI experience) and now it is inability to get new instances. If you look at Quotas and Limitshttp://code.google.com/appengine/docs/java/runtime.html#Quotas_and_Limits there is statement: 'Applications that are heavily CPU-bound may also incur some additional latency in order to efficiently share resources with other applications on the same servers.' So what are heavily CPU-bound applications. Currently only information that we have are yellow and red warnings. I hope that somebody from GAE team will give us more information. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Your edge case definitely confused at least 2 of us. I imagine that

Vlad,
Your case is a bit of an edge case for us. At the time your task is
dispatched, do you have any other tasks still in the queue scheduled
to execute within the next twenty seconds? If not, your queue is
considered empty and will next be checked for tasks to dispatch in
twenty seconds time. If, during this interval, your task that was
running now fails, the task's retry won't be able to run until after
this twenty seconds has elapsed.
If there were other tasks in the queue scheduled to execute during the
twenty seconds after your task's eta, you might find your task meeting
its 7 second retry backoff more precisely.

Re: [google-appengine] Re: Newbie Q - Public IP address_DNS Server?
Unless its an API from one of the 'big players' then its unlikly that the proxy would become a performance bottleneck. ie the proxy will likely out perform the API itself. Or do you mean a problem as a SPOF (single point of failure) - if worried about that then could get two proxies :) And hope the API provider allows you to specify multiple IPs.

[google-appengine] Problem deleting an application
I have an application that I no longer want to pay for. When I go to the disabling administration page it tells me that I can't request permanent deletion because my billing status is enabled. When I try to disable my billing, the status changes to changing daily budget for about 10 minutes and then it goes directly back to enabled. In short there is no way for me to delete this application. Anyone have any ideas? -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Why not SELECT single_property FROM model?
As I know, there are 4 bigtables used for store indexes. So when I try to fetch a single property or a tuple of (single property, key), datastore can only scan the index table, no need to fetch the corresponding entities. That would also be useful when I fetch several properties via composite index or even merge-join.

Re: [google-appengine] Why not SELECT single_property FROM model?
That is something I have wondered about too Keakon. Actually, I thought there was already a feature request for it but don't see it now. It would be really cool to be able to only get the data from the index returned, and not the entire entity.

Re: [google-appengine] Why not SELECT single_property FROM model?
I think the problem is at the underlaying appengine.db implementation (which acts as an ORM) that property belongs to an entity, you will have to have away to know when that model is not fully loaded. Common ORM/Data Gateways problems.

Re: [google-appengine] Why not SELECT single_property FROM model?
agreed and how would you distribute this dict in your application? using it by index key is just a bad practice imho i guess the other option is to have a simplified version of your model, e.g: UserModel (entire model loaded using LazyLoading - pretty much what appengine.db does) IndexedUserModel (just with properties returned by the index) extending http://code.google.com/appengine/docs/python/datastore/keyclass.html ?

[google-appengine] Re: Why not SELECT single_property FROM model?
One major problem I see will be with list properties, I assume each value in the list when indexed will have its own position in the index along with the Key, So if what you describe was implemented you find you could only get a single value from the index that matched. In fact in all cases you could probably only get properties for matches from the index(es) unless you retrieve the whole entity. A lazily loaded entity, ie match the entity, get the key, create a lazy entity, will still have to fetch the full entity to get any property other than those used to find the entity in the indexes. I think ;-) So I am not sure there is a lot to be gained. T -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Re: Why not SELECT single_property FROM model?
I figured it might be of value on things like range scans. Think about uses like this: SELECT key, first_name FROM People WHERE first_name = 'alb' AND first_name 'ablz'; You could have the entity id _and_ the name from the index. Aside from this type of use case, you are probably right -- not much value for equality-only queries. I'm not sure I see an issue with list properties, wouldn't the expectation be to only return the matching element?

[google-appengine] App Engine cannot vacuum indexes - stuck in building state for weeks - need google help
Hi, My app is romanceapp, and I hope that someone from google might be able to have a look at the indexes to see why I cannot remove them. They have been stuck in a Building state for more than a week, which I believe was caused by the fact that I uploaded incorrect indexes and then tried to vacuum them before they completed building. As a result I have used all 200 indexes and have no room to make modifications to my data structures.
