[appengine-java] Query with several filters on same list property potential exploding index problem...
I handle a class MyClass that holds a list property myListProperty. I use the low-level API to query over this class, with a dynamic number of filters over this very single field. Those filters mainly use different kind of operators (inequality filters and in filters). Sample code: Query q = new Query(MyClass); q.addFilter(myListProperty, FilterOperator.IN, oneCollection); q.addFilter(myListProperty, FilterOperator.IN, anotherCollection); q.addFilter(myListProperty, FilterOperator.GREATER_THAN, oneString); q.addFilter(myListProperty, FilterOperator.LESS_THAN, anotherString); When executing this query in dev mode, it generates the following index in datastore-indexes-auto.xml: !-- Used 15 times in query history -- datastore-index kind=MyClass ancestor=false source=auto property name=myListProperty direction=asc/ property name=myListProperty direction=asc/ property name=myListProperty direction=asc/ /datastore-index You got it : this would generate a mega-exploding index problem when in productionŠ Can someone confirm that this kind of index is NOT REQUIRED when executing that query on the actual datastore ? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Could not initialize class PMF
Are you trying to reference PMF in your client side GWT code? This won't
work. It has to be in your server side code. This is what the stack trace
seems to indicate.
If not, I'd say look to make sure PMF is in your classpath.

Re: [appengine-java] Could not initialize class PMF
Hi Laci,
NoClassDefFoundError can mean one of two things:
1) You really didn't include the class in your webapp, so it can't be found.
You should check the classes in WEB-INF/classes and the jars in WEB-INF/lib
to make sure com.reference.server.PMF is present.
2) Your PMF class threw an exception in its static initializer the very
first time the JVM tried to class load it. If this is the case, there should
be an ExceptionInInitializerError somewhere in your logs. In this specific
case, something could have failed in your initialization of pmfInstance.

[google-appengine] Re: ABOUT with_cursor
Oh, I overlooked this description. I see I can't use with_cursor string in URL. Thank you! On 3月8日, 午前7:43, Robert Kluin robert.kl...@gmail.com wrote: Hi, It is fine to use a cursor as a query parameter. A cursor is an opaque base64-encoded string that represents the next starting position of a query after a fetch operation. The app can embed the cursor in web pages as HTTP GET or POST parameters. It is generally safe to pass a datastore cursor to a client, such as in a web form, and accept a cursor value from a client. A client cannot change the cursor value to access results outside of the original query. From: http://code.google.com/intl/en/appengine/docs/python/datastore/querie...

[google-appengine] JDO Drop Columns/Attribute
Hey...
I tried some tests with JDO and the Google App Engine. So I created a
simple object:
@PersistenceCapable(identityType = IdentityType.APPLICATION)
@SuppressWarnings(serial)
public class CareerDO extends CommonData {
public CareerDO() {
}
public CareerDO(String key, Long sort) {
this.key = key;
this.sort = sort;
}
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Unique
protected Key id;
@Persistent(nullValue = NullValue.NONE)
@Index
protected String key;
@Persistent(nullValue = NullValue.NONE)
protected Long sort;
@Persistent
protected SetKey races = new HashSetKey();
}
It works fine and the Set of Keys is the reference for another object.
But what will happen when I don't longer not a field? Ok, I delete the
attributes and remove the annotation. But in my tests, the attribute
ist still alive in the database. So how does it work with a drop or
add column?

Markus Unger

[google-appengine] Errors during downloading data using bulkloader
Hi, I am trying to download some from the datastore using the following command: appcfg.py download_data --config_file=bulkloader.yaml -- application=myappname --kind=mykindname --url=http:// myappname.appspot.com/_ah/remote_api -- filename=myappname_mykindname.csv When I didn't have much data in this particular kind/table I could download the data in one shot - occasionally running into the following error: .[ERROR ] [Thread-11] ExportProgressThread: Traceback (most recent call last): File C:\Program Files\Google\google_appengine\google\appengine\tools \bulkload er.py, line 1448, in run self.PerformWork() File C:\Program Files\Google\google_appengine\google\appengine\tools \bulkload er.py, line 2216, in PerformWork item.key_end) File C:\Program Files\Google\google_appengine\google\appengine\tools \bulkload er.py, line 2011, in StoreKeys (STATE_READ, unicode(kind), unicode(key_start), unicode(key_end))) OperationalError: unable to open database file When that error appeared I would simply re-run the download and things would work out well. Of late, I am noticing that as the size of my kind increases, the download tool fails much more often. For instance, with a kind with ~3500 entities I had to run to the command 5 times - only the last of which succeeded. Is there a way around this error? Previously, my only worry was I wouldn't be able to automate downloads in a script because of the occasional failures - now I am scared I won't be able to get my data out at all. This issue was discussed previously here: http://tinyurl.com/6yh9g5u , but the post is old and I am not sure what the suggested flag does - hence posting my similar query again. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Hello, I have a requirement that my login should only authenticated with the domain name which I have mapped. for example, I have one domain name called www.abc.com . I have mapped this domain with google app engine. There is one login page. When the user not signed in it will be redirected to google login page. There it should check whether that particular user is having the email address of abc.com. (ad...@abc.com). That means only the users under the domain of abc.com.I dont want the user to provide the google login service. I can validate by using username and password.

[google-appengine] appcfg.py download_data
Hello, I was reading the documentation on Uploading and Downloading Data[1]. The second part talks about appcfg.py's download_data and upload_data. The third part talks about configuring the Bulk Loader. When reading that part, when it talks about generating bulkloader.yaml specifically, I noticed it says Note that your datastore statistics can be up to 24 hours old, so if you change your schema, the generated file might not reflect the changes right away. I'm not sure about this, but I assume appcfg.py's download_data uses the bulkloader to achieve its goal. So, I was wondering if there could be any trouble using download_data on a recently changed schema. Should I wait 24hrs before doing a backup if I just changed the schema?

[google-appengine] App Engine TOS question
I am trying to serve two different sub domains (www.domain.com and app.domain.com). The www domain is the primary web site. This will initially be basic html and/or jsp pages. As it evolves there may be some simple servlets driving it. The app domain is the main application I'm developing (and currently my primary focus). It is a standalone application but there will be links between the two sites (www app). My question is - Can I create two App Engine projects to support the sub domains? I understand that using multiple apps to spread out the quotas is not allowed. In this case I'm simply trying to divide up the functional units between the app and the web site. In the future there will likely be more than one application/project. Each of these will be linked from the www domain. In this case it makes even less sense for the sub domains to be combined as they will be unrelated apps. So I guess what I'm asking is if it is OK to create an app strictly for my WWW domain with links to my APP domain?

Re: [google-appengine] Re: Deleting Data Really Expensive!
I'm also interested in this. I have 300 million entities I no longer need, they cost $5 / day to store, but short test with the Datastore Admin seemed to show that they would cost $1500 to delete. Not a nice thing to discover since I'd like to delete them precisely because I need to save money.

Re: [google-appengine] Re: Deleting Data Really Expensive!
Crossposting my reply from stackoverflow.

Re: [google-appengine] Re: Deleting Data Really Expensive!
why would it be cheaper if at the end, the datastore admin creates a map reduce that iterates thru the model via splitting the index and loading each entity per key name ? Each map is a task queue so it is exactly the same :) On 9 March 2011 18:22, Bemmu bemmu@gmail.com wrote: Crossposting my reply from stackoverflow.

Re: [google-appengine] Re: Deleting Data Really Expensive!
I've been given the impression from these forums that the datastore admin tool is so expensive for exactly the reason you've stated David - it loads each entity by key before deletion, whereas deleting purely on keys is much cheaper CPU-wise as you don't need to bother with the retrieval of the entire entity to carry out the delete. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] fetch limit?
Hey Andreas, I can easily fetch several thousand entities (over 5,000) in a single batch -- within a script. The issue is probably because you're doing the fetch from the remote api, all of the entities have to be transferred to the client. You might want fetch smaller batches and use cursors. http://code.google.com/appengine/docs/python/datastore/queryclass.html#Query_cursor Robert On Wed, Mar 9, 2011 at 12:23, andreas schmid a.schmi...@gmail.com wrote: hi, is there still a fetch limit somewhere? i cant really fetch more than 2100 items... if i try to do that i dont get any result in the remote api and i have to kill the query. why is that? ... 2100 is a pretty random number but im seeing this issue on all my apps. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Problems copying entities to the high replication datastore.
I have about 2GB of data that I was copying between applications while porting from a master/slave datastore to a high replication one and the process has completely stopped in the middle. It's been about 12 hours so far and about $80 worth of CPU, and my mappers are stuck in a running state. There are five entity mappers that aren't doing anything that say they are still running. For the first 2 hours of the copy it looked like there was consistent progress and the number of running jobs kept going down and the number of successful shards kept going up, which was of course good. But now there are 5 mapper jobs left that haven't changed progress in 10 hours. The major ones still show about 3 shards left to complete and one shows 8 shards left to complete (out of 32 shards). So, do I need to start over with my copy? I'm ok with that except that I really don't want to spend another $80 just because it broke the first time. And does anyone know why the mapreduce jobs would just go idle? I'm afraid that if I start it over then the same thing will happen and I'll be out another $80 without any real progress. (updated: I just retried a few of the entities again and each of the 5 types of entities gets stuck at the same point, One entity I tried always gets stuck at 3 shards left out of 32 and another one instantly gets stuck on 1 shard out of 1 shard. I thought maybe the updates had gone through even though they said they didn't, but when I look at the datastore admin it shows a lower count for the number of entities and when I go to the app it throws an error saying a reference property failed to resolve, when the original app doesn't have that error with the same request) A side question: It looks like blobstore values are not copied over and I don't see a way to do that. Is there any way currently to do that? We have about 9GB of blobstore values that we need copied over and a lot of them are over 1MB in size so we can't use the urlfetch trick to do it. Please help as soon as you can because our database is stuck in read only mode until we can figure this out. We would rather not pay another $80 or more later by going back to the the master/slave database.
