Re: [appengine-java] max keys for memcache
There isn't a limit per se (that I know of), but our implementation of Memcache has two LRU (least recently used) queues that are used to expire content based on recency of access: a global LRU for that particular Memcache instance, and an LRU for your app. The amount of memory used is subject to change and I don't know it off the top of my head. I suspect you will not be able to store a billion keys, however, as I am pretty sure this'll go over the per app memory limits. So the bigger question here is this: are you familiar with the concept of a working set in computer science? Chances are good you will not need all billion keys equally. Why not store all these objects in the datastore and only store the most accessed in Memcache? The easiest implementation will be to check memcache first before checking the datastore, and Memcache's LRU expiration will just take care of the rest for you. -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com On Mon, Feb 13, 2012 at 4:18 AM, Luke travalle...@gmail.com wrote: Is there any limit of maximum keys i can store in memcache in any particular time.

Re: [appengine-java] lost trying to understand JDO on BigTable: please help coding example
You don't need to implement a Primary Key class. Specify the primary field
as a Key and generate the key using KeyFactory:
http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/datastore/KeyFactory.Builder.html
You can autogenerate IDs with this method:
http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/datastore/KeyRange.html
You'll probably get more mileage persisting the object in a single entity
(treating the datastore more like a key-value store) and using a
translation later to turn it into classes to work with than trying to do
magic trying to get these classes to persist the way you want them to. In
my opinion, you're not sacrificing code readability - you're just moving
work around.

Tough. I cannot sacrifice code readability here.
If you do have a good reason, you could still persist them as a single

Re: [appengine-java] OAuth and google chrome
This is strange - there should be nothing browser specific about the session. Try to isolate the behavior by removing OAuth out of the equation.

Actually, I took a look at these docs and it seems like we do talk about cross group transactions. There are a few areas where we talk about exceptions being thrown for transactions on entities in different entity groups, but that's expected behavior.

Re: [appengine-java] Re: problem with Content-type: null with css files
Re: Carter Going a bit off topic, but in general I have always worked at places that stage deployments. That is - you have some environment only accessible by your team that reaches live data after your verification and QA more or less have determined that in the worse case scenario, your change is not destructive in a non-recoverable manner. Alternating versions is a very good way to do this; it also offers you a very easy rollback path. Being able to rollback quickly is absolutely key to working fast when things go sour. If it were me, I'd always alternate versions on deploy and manually switch versions when I have confidence the new version is good, but you've got to find that practice that works best for you. There are bugs that only rear their heads in production. The App Engine team more or less does major version releases by deploying to test clusters, internal clusters, and then, via canarying, to the production cluster. The way staging is usually done for new APIs is that new APIs are usually available in production before we announce the release (they may only be accessible to our whitelisted apps) so we can test that, in production (because production is always a jungle), the new APIs work well. We never do a rollout without first having a rollback plan, which is what you get by alternating versions when you deploy your applications. -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com | twitter.com/ikai On Fri, Jan 13, 2012 at 12:40 PM, Carter Maslan car...@maslan.com wrote: Ikai - Our site was unusable for 30 minutes while we quickly downloaded the 1.6.1.1 fix and redeployed with the new SDK.

[appengine-java] Announcing - Java Threads Trusted Tester program
Hey everyone, We're announcing a new trusted tester program for Java developers: Java threads. This is a feature we’d like to release sometime in one of the next upcoming versions. You’d be able to create Threads using a ThreadFactory (so existing libraries that create threads through other means won’t work) and run these threads within the scope of the request. The Javadocs for this feature are already online: http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/ThreadManager.html Note that if you try to deploy your application and your application has not yet been whitelisted, this will cause your application to throw a FeatureNotAvailableException. If you’re interested in taking this feature for a spin, please sign up here: https://docs.google.com/a/google.com/spreadsheet/viewform?formkey=dEstOEluU0RLdHpLRDhva0J3WDJQQWc6MQ If you are selected, you’ll be added to a Google Group where you can ask questions and provide feedback on the API. Please only sign up if you are actually interested in running this; if you don’t plan on running this on App Engine servers (either in a QA/test, staging, or, if you are brave - production!) I suggest you just test it out on the local SDK or wait for general release. You’ll need to sign an electronic NDA if you haven’t signed one before (this is pretty standard of all of our trusted tester releases). I’ll begin sending out NDAs and whitelisting users next week. -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Hi there! - a logged in user could manipulate the RPC call (he could for example exchange his userID by the ID of someone else and access the data of this user) - to avoid that I need to verify that the user ID matches the session ID assigned when he logged in. Can you describe how your code works that makes this an issue? If you're using the Users API, it shouldn't be a problem, but I suspect you are doing something where a native client call is directly translated to a low level datastore API call. -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com | twitter.com/ikai On Wed, Jan 11, 2012 at 7:18 AM, meiaestro jmalbre...@gmx.de wrote: Hi all! ** ** I was thinking about making my RPC calls to the server (datastore commands) more secure against java script or data stream modifications on client side (when user is already signed in and validated). ** ** Problem: - right now all datastore requests are transmitted 1:1 from client to server via RPC calls. - a logged in user could manipulate the RPC call (he could for example exchange his userID by the ID of someone else and access the data of this user) - to avoid that I need to verify that the user ID matches the session ID assigned when he logged in. - Idea: I want to proxy every request through a single method on server side and only if the user is validated against his session the specified server method is called. ** ** Not a clue how to implement: - specify an Interface with all datastore methods available. - sending a method call (which is defined by the interface) via RPC call to the server - within the proxy method on server side verify the user and execute the method call - if applicable return the return value asynchonously Is this a common approach?

[appengine-java] Minor update to Java SDK: 1.6.1.1
Hey everyone, There's a new version of the Java SDK available for download. You can get it here: http://code.google.com/p/googleappengine/downloads/detail?name=appengine-java-sdk-1.6.1.1.zip It's a minor version bump. We had to address an issue with the Java SDK that was causing CSS files to upload with an empty mime-type, breaking CSS rendering in many browsers. The official App Engine download page will be updated shortly. We recommend that anyone developing Java apps using SDK version 1.6.1 upgrade to this version. I want to thank everyone who helps us nail this bug, namely, Jon, Brandon, Raffaele, Pieter and James. If I missed your name I apologize!

Re: [appengine-java] Re: problem with Content-type: null with css files
Are you all on the 1.6.1 SDK? Is someone experiencing this deploying with an older SDK? If someone has a deterministically reproducible case that you can share with us (project files and everything), it'd be very helpful for us to nail this bug. We aren't able to do this with our test apps (big apps, small apps).

Re: [appengine-java] Re: problem with Content-type: null with css files
It sounds like the data about this XML snippet is still inconclusive. - Jon Stevens reports that if you change the extension to .css, it works - Matt, in addition to using Jon's fix to the fix, you needed to increment the version to fix the broken mime-type So it's possible the XML snippet might be a red herring and it's something in the deployment/version incrementing mechanism that fixes something about the file being in a bad state.

Re: [appengine-java] Re: Indexes - how to deal with them?
Paul, yes. Whenever you update an entity, any property that is not explicitly marked as unindexed will generate 2 index writes. Any update to that property will cause 2 writes to delete the old indexes and 2 writes to write the new ones. The indexes are used in queries, e.g.: select from user where name='bob' If you don't have the 'name' property indexed, you won't be able to run that query. If you never run a query against a property, mark it as unindexed. -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com | twitter.com/ikai On Thu, Dec 22, 2011 at 12:02 AM, Paul pgronkiew...@gmail.com wrote: Also, another question: I don't even have datastore-indexes.xml generated, should I even have any index write ops possible without it? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] LocalDatastoreServiceTestConfig does not keep modificatins
This is to be expected. You're tearing down the helper between test runs.
All tests are green because you are not using assertions. Example:
assertNotNull(someInstance);
There's something very bad happening in these tests: you don't ever want
state to leak across tests. This is a very bad practice. You want each test
to exist in its own universe. When state leaks across tests, you become
dependent on the order of the tests being run (not guaranteed). You also
can't parallelize tests (this is important to some people). Your tests also
become incredible brittle because if a single test fails in the middle of
the chain, you have a ton of tests that will fail after it that you might
never be able to fix because they were all dependent on a state change in
the failing test - you want that test and only that test to fail.
Here's how you should write the test instead:
@Test public void testFetch() {
final EntityController ec = new EntityController(); // There's
no point caching this. Again, don't want to leak state.
final Flight flight = new Flight(origin, destination); // There
also isn't really a point in making any of these final, but that's a minor
nitpick
ec.create(flight);
Flight returnedFlight = ec.find(Flight.class, 1);
assertNotNull(Should be able to find a Flight that was just
created, returnedFlight);
}

Re: [appengine-java] May datastore reuse a deleted entity key?
If you are using auto generated keys or keys generated using the allocateIds() method, no, this should never happen. In fact, any key created using allocateId will never appear again even if you never save an entity with that key. One thing to note is that that IDs are not monotonically incrementing (ID 1, 2, 3, 4, 5 ... etc) - this is very hard to do in a scalable fashion. IDs more or less are increasing, but we cannot guarantee that the ID of an entity will be greater than an entity saved before it (you might concurrently allocate two batches of IDs, for instance). -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com | twitter.com/ikai On Thu, Dec 15, 2011 at 8:59 AM, Juna juan.meng...@bcntouch.com wrote: Hi, I have been looking info about this and I haven't find an exact answer (or I haven't known read the answer).

Re: [appengine-java] Design principles for a class with a lot of parameters
There are 2 main differences: 1. Indexes. You probably want to mark most of the items as unindexed to lower the cost of a datastore write and datastore storage. 2. Possible serialization/deserialization time. Items are stored as protocol buffers (http://code.google.com/p/protobuf/). I don't know off the top of my head how this performs with large arrays versus individual properties. My suspicion is that there shouldn't be a real world difference, but I haven't verified this with my own testing, and I don't know how many properties you have in mind.

Hoping I can get some info on if we did anything wrong but mostly wanted to relay the experience for others. I did a couple of test migrations the week before, running the migration tool through to the end and reverting at the last create alias step. I also ran through the process in its entirety with our staging and build environments. It always ran smoothly (Note the use of the ellipsis above. It's what legitimate journalists refer to as foreshadowing. Or possibly foreboding.) First hurdle: When it came time to start the migration, the Datastore Admin tool didn't appear in the console for the destination. Normally, I'm used to it not showing up in Chrome but this time, it was blank in Firefox too. IE showed a generic HTTP error page. I needed it so I could clear out the data from the destination leftover from previous migration tests. I had already deployed the same version of the app that was currently in the Master/Slave version. Eventually, I looked at the source of the admin console and found the URL for the iframe it used and launched it directly in Firefox. It was confused which of the three active Google accounts I regular use should be logged in so I chose the correct one and carried on, deleting the existing data. Next, I launched the migration tool. It hung on the Copy phase (the second step). I let it go for about half an hour. (During my trial runs, it took less than ten minutes.) So I reverted and went back to the Datastore Admin tool (which now appeared properly in the Admin Console, at least in Firefox) and deleted all the data. I went to the Datastore Viewer to verify and could not access it. I received a 500 Server Error with a link to report the error on this group. (Incidentally, I am not a big fanhttp://codebetter.com/kylebaley/2011/04/25/google-ui-faux-pas-or-how-to-show-love-hillbilly-styleof the new Google Groups, especially for AppEngine which has three to choose from) I relied on the Datastore Admin tool to tell me that the data had been cleared and tried the migration again. Once again, it hung on the copy phase, this time for almost an hour before I reverted. While it was doing its thing, I checked the Datastore Admin tool on the destination and almost from the start, it showed entity totals that were *almost* as high as the source. But they didn't move during the entire time I waited. I suspect it was reporting on old data. After reverting, I gave up on the migration tool. Before starting the whole process, I had done the following: - Switched the source app to a maintenance version that redirects all traffic to a maintenance page (and if a user is already running the app, the page is refreshed to show the maintenance page). - Backed up the data So I restored the backup to the HR app and all seems to be running smoothly on it. The source doesn't have an alias to the new app but I didn't intend to use one anyway. That's my migration experience. The app is up and running now and we just barely did it under our budget thanks to all the database reads and writes. An app that normally costs us about ten cents a day cost us almost $4.00 last night. In summary, the major parts I'm not happy with: - Datastore Admin page not showing up in any browser - The migration tool apparently not working. (There's a chance it was actually doing something and I reverted prematurely but my earlier test runs suggest something went wrong.) - 500 Server Error on the destination's Datastore Viewer. Furthermore, it seems unprofessional to direct support to a Google Group for a paid application. The 40x cost increase for the migration I'm okay with. Four dollars still isn't a lot of money. That said, I'm not sure what I would have done had we reached our budget. I'm not the billing administrator for either app. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Re: Number of writes per second limitation
If all 4000 entites are in a single entity group, in theory you can do this because it counts as a single transactional write. There's a maximum RPC size of 11mb (implementation detail) so if you trip this, you're in some trouble - the RPC size include not only the size of the entity but also the size of all the indexes. The problem is that this is a bad design. App Engine charges for datastore ops, so you're already using 4000 datastore write ops per request + multiples for indexes. Instead, try to figure out how to can write the data in as few entities as possible. I suspect you're still thinking relationally. You didn't answer my question about what problem you're trying to solve. What are you building? Why would 4000 writes be needed?

Re: [appengine-java] Correct way to keep track of the number of Entities of one kind.
So I hate to make this more complicated but ...
Yes, this is roughly the right approach. However, if you are creating
entities at a rate higher than 1/s, this pattern will break. You'll need to
use the sharded counter property:
http://code.google.com/appengine/articles/sharding_counters.html
The example is in Python, but hopefully you understand what's happening
there.

This number can be very high so I don't want to calculate it when i query
the data and implemented a class which holds the number of Entities:

import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.PrimaryKey;
@PersistenceCapable
public class Aggregate {
@PrimaryKey

public void setName(String name) {
this.name = name;
}
public int getCount() {

}
public void setCount(int count) {
this.count = count;
}
}
To update the count value I do something like that.
@PersistenceCapable
public class SomeEntity {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
..
public SomeEntity() {
// increment the count
PersistenceManager pm = PMF.get().getPersistenceManager();
try {
Aggregate aggregate = (Aggregate) pm.getObjectById(Aggregate.class,
SomeEntity.class.getSimpleName());
int count = aggregate.getCount();
count++;
aggregate.setCount(count);
pm.makePersistent(aggregate);
} catch (JDOObjectNotFoundException jonfe) {
// the first someEntity ever
Aggregate aggregate = new Aggregate(Player.class.getSimpleName());
aggregate.setCount(1);
pm.makePersistent(aggregate);
} finally {
pm.close();
}
}
.
So far, this works, but I really don't like the way how it's done. Are
there any implemented tools in google app engine to handle something like
that? Or is this the correct way to keep track of the number of entities?

[appengine-java] Prerelease SDK 1.5.5 available for download!
Hey everyone, Prerelease SDK 1.5.5 is now available for download! You can get it here: Python: http://code.google.com/p/googleappengine/downloads/detail?name=google_appengine_prerelease-1.5.5.zip Java: http://code.google.com/p/googleappengine/downloads/detail?name=appengine-java-sdk-prerelease-1.5.5.zip We provide prerelease SDKs as previews for things to come. New features should not work in production yet, and documentation is typically still a work in progress. Release notes are below as well as in the prerelease packages: Python === - Python 2.7 is now available as an experimental runtime for all applications using the High Replication Datastore. To upload your app to the Python 2.7 runtime, change the runtime argument in your app.yaml to python27. - We have released an experimental utility, available in the Admin Console, to assist in migrating your application to the High Replication datastore. This utility allows you to copy the bulk of your data in the background, while the source application is still serving. You then need a brief read-only period to migrate your application data while you copy the data that has changed from the time the original copy started. - We have increased the number of files you can upload with your application from 3,000 to 10,000. - We have increased the size limit for a single file uploaded to App Engine from 10MB to 32MB. - We have increased the Frontend request deadline from 30 seconds to 60 seconds. - We have increased the URLFetch maximum deadline from 10 seconds to 60 seconds. - We have increased the URLFetch Post payload from 1MB to 5MB. - App Engine now supports Cross Group (XG) transactions with the High Replication Datastore, which allow you to perform transactions across multiple entity groups. - We have released an experimental API that can write to Google Storage for Developers directly from App Engine. - We have added a graph to the admin console that displays the number of instances for which you will be billed. - In the XMPP API, get_presence() is deprecated in favor of using the inbound presence handlers documented in http://code.google.com/appengine/docs/python/xmpp/overview.html#Handling_User_Presence . - The Task Queue API 'target' parameter now accepts a new value, taskqueue.DEFAULT_APP_VERSION, which will send the task to the default frontend version, rather than the version or backend where the 'add' method is being called. - In the URLFetch API, make_fetch_call() now returns an RPC object. - Fixed an issue in the Admin Console where the Run Now button did not work for tasks with a '-' in the name. - Fixed an issue where the SDK did not decode Base64 encoded blobs. - Fixed an issue to provide a better error message when using the Mail API to send email to an invalid user address. - Fixed an issue in the SDK where a skip_files entry caused an ImportError when the library was located elsewhere in the PYTHONPATH. - Fixed an issue in the SDK index viewer where the arrows indicating whether a query was ascending or descending were not properly rendered. - Fixed an issue where httplib did not support the deadline argument for URLFetch calls. http://code.google.com/p/googleappengine/issues/detail?id=2216 - Fixed an issue where you could not schedule a cron job to run every 100 minutes. http://code.google.com/p/googleappengine/issues/detail?id=5243 - Fixed an issue in the SDK where failed tasks retried immediately instead of waiting for 30 seconds. http://code.google.com/p/googleappengine/issues/detail?id=5587 - Fixed an issue making it possible to modify request headers using the deferred library. http://code.google.com/p/googleappengine/issues/detail?id=5861 Java = - We have released an experimental utility, available in the Admin Console, to assist in migrating your application to the High Replication datastore.

Re: [appengine-java] Re: Howto return all values stored in memcache?
The publicly available Memcache doesn't have this functionality either, and
it's really not as simple as you might think. What if there's a lot of data?
Do you need a cursor? Should you lock all Memcache shards? And so forth.
If you're interested in a project that does something similar, you should
check out Redis. It's a key/value store with data structures that exists all
in memory, where values are asynchronously flushed to disk.

Thanks for your example, although I found it a little difficult to

belonging to all the other entities in the cache? Would this allow me
to iterate through the keys, saving the entity to the datastore and

Also what is the putIfUntouched statement for?

You could create a key with all entities ids that need to be updated.
Something like:

}
and then
public void entitiesToUpdate(Long id) {

Re: [appengine-java] datastore - order by query in a many to many model
Hi Gabriel,
Ah, you're hitting the first bump in learning to think
non-relationally. Rather than creating 3 models, what about creating a List
of categories for each Podcast and just storing that on the podcast? The
tradeoff is that it won't be easy to rename a podcast category, but that
shouldn't be something that happens frequently.
When designing for the datastore, aim for designing for a key-value store
when possible, and don't think in terms of joins.

then I would have to sort them in my app by addedDate.
I feel that something is wrong, maybe my query or my data modelling. I

Re: [appengine-java] Memcache objects remain only 5 minutes
You're right: there are no guarantees around how long an item will stay in Memcache. Memcache has two Least-Recently-Used lists of items, where if you don't read or write an item, it may be pushed off the list for space. There's a per app LRU and a global LRU for apps sharing the same memcache instance. 5 minutes seems extremely short (typical eviction time of an untouched item is on the order of magnitude of a few hours), however, and I'm fairly certain with your memory size it's probably not the local LRU. I don't have any suggestions for the moment, but perhaps you can track the hit rate with getStatistics and try to determine some patterns? http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/memcache/MemcacheService.html#getStatistics() -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com | twitter.com/ikai On Tue, Sep 27, 2011 at 2:11 AM, Peter Nees peter.n...@unclestock.comwrote: My objects remain in the memcache only for about 5 minutes.

[appengine-java] App Engine SDK 1.5.4 released!
Hey everyone, Just wanted to let you all know that App Engine SDK 1.5.4 has been released. The official announcement is here: http://googleappengine.blogspot.com/2011/09/app-engine-154-sdk-release.html The full release notes are below: Java 1.5.4 = - You can now specify the maximum size for a blob in BlobstoreService.createUploadUrl(). - Zigzag merge join queries will now continue scanning up to the 30 second Datastore query deadline. For zigzag queries that used to generate DatastoreNeedIndexException, many will now succeed. A small percentage will now instead timeout. - The SDK datastore viewer in the dev console now displays the number of Write Ops for each entity. Write Ops are the total number of entity and index writes that were required to create the entity. - The Prospective Search API is available in Java for all applications. This API is still experimental, so applications will be limited to a maximum of 1000 subscriptions. - We made a classloading improvement that we expect to help loading request latencies for projects with large numbers of jars. - Added support for the set_default_version flag to Appcfg. - The Java Remote API now recognizes the HTTP_X_APPENGINE_INBOUND_APPID. This means that the Datastore Admin copy functionality will work when using Java's Remote API with the destination app. - Fixed an issue that incorrectly allowed creation of tasks with whitespace in the url. - Fixed the error message for transaction not found to be more descriptive. - Fixed an issue with the dev appserver's local Blobstore implementation trying to modify an immutable collection. http://code.google.com/p/googleappengine/issues/detail?id=3081 - Fixed an SDK issue where CONFIG, FINE, FINER, FINEST logging messages were not displayed. http://code.google.com/p/googleappengine/issues/detail?id=4591 -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com | twitter.com/ikai -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] New Billing Model,
Without knowing what you are doing, as a general suggestion I say use rough approximations and charge per op instead of trying to match App Engine's pricing cent for cent. A few months ago, someone in this group posted a very good analogy about how everyone pays the same amount of money at a buffet even if they eat different amounts of food; that's the level you should be thinking about pricing. Doing your suggested pricing is also difficult because when you turn on multithreading (concurrent requests, you WANT to do this), it will be a bit harder to map exact amount of milliseconds used per request because you could potentially be serving many requests in parallel. We did something similar with cpu_ms pricing before, where some operations always cost a certain amount of ms no matter what, even though in real life there was a lot more variance due to network congestion, CPU congestion, etc. One more pricing analogy: lawyers have systems that track how long they spend on the phone. They don't do this to pass the cost of the long distance phone call to their clients (cents). They do this so they can (at least in my experience) round up to the nearest 5 minute increment and bill at $400-$1000 dollars an hour. -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com | twitter.com/ikai On Fri, Sep 9, 2011 at 2:57 AM, Tom Taylor ttay...@encircle.co.uk wrote: Hi, We are currently developing a multi-user Java application on App Engine where we want to pass on the cost of the computing resources used to each individual user (plus our markup of course). The computing resources are composed of tasks placed on the task queue. The url of each item on the task queue can easily be related back to a specific user. Inside the tasks we make a few data store calls and some memcache calls and some urlfetch calls (as we're using the gdata apis to talk to Google apps apis). My question is: we were planning to use the *QuotaService *api to get the cpu cycles used and charge accordingly - but under the new billing model, as I understand it, this is no longer appropriate. Can anyone suggest a way forward with this? I have set up the appstats module - and it seems all the info I need is available to do the calculations under the new billing model - but can I get to this information programatically. I've had a good search through the api docs and didn't find anything. As a side note we are using multi tenancy for the datastore - with the userid as the namespace. So I think I have the datastore resources used per user under control. regards Tom -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] ApplicationError: 10: Unknown when writing to blobstore using FileService
We're surfacing a bad error here. Basically, you get this error message if
you hold the file open too long; we recommend around 30 seconds.
I'll file a bug internally to get a better error message. Can you break this
up into multiple writes?

Re: [appengine-java] Does the SDK in WEB-INF/lib Get Deployed?
Yes, these get deployed, and yes they are needed online because they provide the interfaces to the APIs. These are essentially thin clients. Fortunately, because we calculate a hash on each of the files, they're not reuploaded each time because we already have an identical file online.

Re: [appengine-java] How to increase mapper quota?
What's your task queue quota set at? -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com | twitter.com/ikai On Fri, Aug 12, 2011 at 1:01 PM, Rob Patel robpate...@gmail.com wrote: I am using google app engine Mapper API to delete all rows (approx. 2M) for a particular entity in my GAE datastore. However, even though I have a billed account, I still get - com.google.appengine.tools.mapreduce.MapReduceServlet processMapper: Out of mapper quota. Aborting request until quota is replenished. Consider increasing mapreduce.mapper.inputprocessingrate (default 1000) if you would like your mapper job to complete faster. How do I specifically increase the mapper quota? I need to remove the records urgently, but cannot find any documentation to increase mapper quota. Can someone please help? If there is any other best practices I should follow, please let me know. thanks! -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
