[appengine-java] Re: Best Java Web Frameworks for GAE (aka speed)
Try http://www.playframework.org/ and http://www.sienaproject.com/ as a persistence layer. It's bigger weakness is that is not based on servlets. So needs hacks sometimes. But in my opinion Python frameworks are better suited to GAE. For example we have JDO, JPA, Siena, Objectify and couple of other persistence layers for Java and none of this is perfect. Storing data in Python is easier and there is no need to add another framework. I would like to have small, extensible, easy to use microframework like Flask or Tipfy for Java.

It looks like you can delay tasks via API : TaskOptionscountdownMillis(long countdownMillis) Set the number of milliseconds delay before execution of the task. TaskOptionsetaMillis(long etaMillis) Sets the approximate absolute time to execute.

[appengine-java] Need help choosing a frontend framework for a GAEj app, GWT seems like overkill
Hello all, A little background... I'm mostly new to web frontend development, I come from a mostly backend and desktop background. I have a GAEj app that provides the backend for a rather sophisticated desktop/mobile app. This backend will also drive a website in addition to the desktop/mobile app. The website will show a small subset of the data in the system. I started with GWT, but it doesn't seem to be quite right. The website is for presentation of a small subset of the system's data only, and users do not interact with the data in any way other than searching for it. As the data is mostly unstructured text and some images, I feel most comfortable formatting it with plain old html/css. In fact, the layout of the site will be minimal and look a lot like a blog. As such, the website should certainly not feel like a single-page web application a la gmail. With GWT, I have little use for widgets and find myself constantly fighting with it to get a non-application look- and-feel. The only functionality that I thus really need from GWT is the RPC component, the page should be AJAX, I don't want to do round trips to the server for every navigation event. So, I'm not quite sure which framework to use with the GAEj backend. At first GWT seemed like a natural fit, but now seems like overkill. I'm doing some research on jquery, but I haven't seen a list of frontend frameworks that play well on GAEj anywhere.

[appengine-java] Re: Need help choosing a frontend framework for a GAEj app, GWT seems like overkill
Hi Mike, I think the reason we don't explicitly publish a list of frontend frameworks that play well with App Engine is because there really is no technical barrier between front end frameworks that work in the browser such as JQuery, etc and the backend (App Engine). Many App Engine users make full use of a myriad of front end technologies/ frameworks for UI creation ranging from HTML5/JS/CSS to flash etc. JQuery is especially popular for a variety of Web app usages, so if that works for you, I'd definitely continue trying it out.

[appengine-java] UrlFetch api, gzip, and quota
Hi, I am making a lot of calls per day to parse html files, and already at low activity notice that my Incoming Bandwidth quota is just being eaten away. After some debugging I noticed that my responses were being received in plain text, and not gzip as I had expected. After some digging, and from this thread: http://groups.google.com/group/google-appengine-java/browse_thread/thread/5c5f2a7e2d2beadc/b0775619b02b27bb?lnk=gstq=urlfetch+gzip#b0775619b02b27bb , I found out that GAE does behind the scenes work, and you actually do receive it as gzip, it is just uncompressed before you get to handle it yourself, correct? If this is the case, and it is the gzip'ed bandwidth that is accumulated to quota, I just can not get it to add up with the rate at which it is increasing. The pages I hit average 5-8kb gzipped, yet if I take the quota thus far, and divide by the UrlFetch api call counter, I am seeing an average of around 22kb. Anyone have any ideas here?

[appengine-java] Catching HardDeadlineExceededError
Hello, I am using GAE with Java have been seeing HardDeadlineExceededError for some tasks running in the task queue. I searched for ways of catching this error, and have tried to catch it using DeadlineExceededException in places where I query the datastore (esp. delete queries with filters), as well as in the task Servlet. However, the DeadlineExceededException never appears to be thrown, and hence my catch blocks (which just log warnings) are not executed (the warnings are not in the logs). I also tried to replace the DeadlineExceededException with RuntimeException and tried to log the messages in the catch block. Again, the GAE logs do not reflect any such data. Further, for many of the tasks another form of message (warning) appears in the logs: Request was aborted after waiting too long to attempt to service your request. This may happen sporadically when the App Engine serving cluster is under unexpectedly high or uneven load. If you see this message frequently, please contact the App Engine team. Appreciate any response on the best way to catch and proces the HardDeadlineExceededError in Java?

Re: [appengine-java] Replace an object in the datastore with another not currently in the datastore?
With the low-level API, you would just set the Key of the old object to the one one and persist it. With managed persistence via PersistenceManager or EntityManager, I believe you can set a key and merge (but I'm not sure off the top of my head). On Wed, Sep 8, 2010 at 12:43 PM, Shaun shaunc...@gmail.com wrote: This might be very obvious, but imagine you have an object in the datastore that you simply want to to replace with another, i.e. keep the same key, just replace all the field values. Is there any easy way to do this without setting each field value of the datastore object with field values of the other object? As an example I find myself doing this alot: ExpenseEntry lJsonExpenseEntry = gson.fromJson(pExpenseEntryJson, ExpenseEntry.class); ExpenseEntry lExpenseEntry = pm.getObjectById(ExpenseEntry.class, expenseKey); lExpenseEntry.setExpenseamount(lJsonExpenseEntry.getExpenseamount()); lExpenseEntry.setExpensecategory(lJsonExpenseEntry.getExpensecategory()); lExpenseEntry.setExpensedate(lJsonExpenseEntry.getExpensedate()); lExpenseEntry.setExpensename(lJsonExpenseEntry.getExpensename()); lExpenseEntry.setExpensenotes(lJsonExpenseEntry.getExpensenotes()); lExpenseEntry.setExpenseuser(lJsonExpenseEntry.getExpenseuser()); lExpenseEntry.setProjectid(lJsonExpenseEntry.getProjectid()); in order to update the datastore object, ideally I could do this all in a few lines by simply replacing the current datastore object with the new one. Maybe just removepersistence and then add it again? Thanks for the thoughts. Shaun -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Catching HardDeadlineExceededError
There is no way to catch a HardDeadlineExceededError. However, you should be getting a DeadlineExceededException first. Perhaps it is being caught and not properly logged by your code or some third-party library that you are using? If you would like help debugging this let me know your application ID privately and I will verify that everything looks correct on our end. On Thu, Sep 9, 2010 at 8:27 AM, armanuj arun_rama...@yahoo.com wrote: Hello, I am using GAE with Java have been seeing HardDeadlineExceededError for some tasks running in the task queue. I searched for ways of catching this error, and have tried to catch it using DeadlineExceededException in places where I query the datastore (esp. delete queries with filters), as well as in the task Servlet. However, the DeadlineExceededException never appears to be thrown, and hence my catch blocks (which just log warnings) are not executed (the warnings are not in the logs). I also tried to replace the DeadlineExceededException with RuntimeException and tried to log the messages in the catch block. Again, the GAE logs do not reflect any such data. Further, for many of the tasks another form of message (warning) appears in the logs: Request was aborted after waiting too long to attempt to service your request.

You might want to look into Sitebricks which is a Google developed web app framework built on top of Guice. It is a simple request response processor with no fancy component abstractions like Wicket or Tapestry. This model fits in very well with GWT (or other client frameworks) which request data via RPC or small snippets of rendered html to assemble on the client. It is still very much in active development so you have to be prepared to dig into the code and figure out the plumbing yourself.

On Sep 8, 10:26 pm, Peter Petrov onest...@gmail.com wrote: This generally happens when you set a custom expiration time for static files. This causes Google's frontend servers to cache the files for up to the specified time, and they don't update it even if you push a new version in the mean time. This is true both for *.appspot.com and for custom domains. You can take a look at the HTTP headers returned by your Google Frontend server, e.g. using Firebug, to see when the next refresh will happen. If you don't set custom expiration for static files, the frontend servers seem to fetch the resources every time (or at least very frequently). On the other hand, the browsers' caching behaviour is then undefined. In any case, you should use cache-busters.

[google-appengine] Re: Idempotence multiple task execution
Hi Eli, notes below - On Sep 8, 4:14 pm, Eli Jones eli.jo...@gmail.com wrote: Well, I've been doing named, chained tasks since November 2009, and I can point out three things: Task names aren't especially relevant to the question - names stop the same task being raised twice, not executed twice. I have been using the task queue since it was released, and definitely noticed tasks being executed more than once, but never concurrently. 1. I've had concurrent tasks execute at least once (that I noticed) when only one was supposed to run.. And, this appeared to happen when the subsystem first fired off the task (after it had already been added to the queue.. since TombstonedTaskError and TaskAlreadyExistsError seem to work nicely.). Well, from Ikai's comment it would sound like google does not expect this behaviour. I raised this thread through hypothetical analysis of the technology, but if you have seen it happen, then that is especially interesting. I personally can't see how it could legitimately happen if it backs off for more than 30s - it would be a bug in the system for the task to fire duplicates when it is first raised, IMO. How did you determine the execution was concurrent? 2. The GAE doc that I linked to explicitly states it is possible in exceptional circumstances that a Task may execute multiple times. I believe that this covers both cases of the same task running concurrently or sequentially. I don't think it does, but this is specifically the point of this thread - it is not clear. I don't want to engineer significant overhead into my application based on interpretation of unclear documentation. To me, the same task id executing at the same time in app engine, if it is possible, is something that needs to be explicitly documented, because it has significant impact on app architecture. Again, Ikai's comment above seems to imply Google does not expect this to happen. So if the documentation is unclear, and google seems to suggest the opposite of your interpretation, that's a good reason to be wary of the assumption you are making. 3. For my failed tasks, I'm pretty sure the backoff has always been more than 30 seconds (if the task failed in the middle of running). Generally, if a task failed in the middle of running, it would run again 60 seconds - 120 seconds later. It hasn't. Absolutely, definitely used to retry immediately and back off at incrementally larger intervals that were initially 30s. Worked like this for quite a long while. Indeed, people other than me suggested this behaviour should be changed to 30s plus to deal with the issue in this thread. I had many, many situations where I had a bug in a task, and the work it generated straight after failure would fill up the error logs almost instantly. It was a real hassle for a while there, and one of the reasons why I raised this issue in June last year - http://code.google.com/p/googleappengine/issues/detail?id=1771 (among a bunch of others). I wouldn't have suggested backoff should be changed to 30s if it was already the case. I can see how one would like the doc to explicitly address the potential for concurrent execution.. but you should presume that it is possible since the doc infers it.. and the doc doesn't say it can't happen.. and (less importantly) some guy on an internet news group is telling you that it has occurred in the past. I don't think the docs infer it. I think it is ambiguous, especially in relation to Ikai's comment. I personally cannot imagine how one could guarantee that this would never happen without bogging down the entire taskqueue subsystem with triple and quadruple checks and adding in random (1-3 second) wait times for exactly when any task would execute.. (but, I have a limited imagination).. and it seems like even then.. you cannot guarantee 100% that a task would not execute twice at once if a drastic system error occurred. Executing twice is fine, I get that. Executing the same task id concurrently seems to be something that can be avoided - I don't see anything other than the 30s+ backoff being required to achieve this. Maybe that's wrong, but its sufficient for me, and was the suggestion I made to address it. Unless someone highlights another reason why it could occur, I'm glad to avoid the additional architecture.

Re: [google-appengine] Re: Idempotence multiple task execution
How did I determine concurrent execution? I determined that I had concurrent task execution because you can see the task_name in the logs, and a named task successfully ran twice. And, the one that ran last threw a TaskAlreadyExists error when trying to add the next chained task to the queue since each named task has a specifically defined name for the next task in the chain and the version that finished first had already added the next named task to the queue. (This is why it is absolutely important to use named tasks when chaining.. some sort of random error can fork your tasks). Why do I suggest tasks do not just retry immediately (or in less than 30 seconds after failure).. and have done so in the time before your April 23rd e-mail. Here are some logs showing a task retry on Feb 22nd (it's hard to find many examples since Appengine Logs only keep error logs after a few months.. so I need to find two errors in a row for a task to see the retry). The task's first run was at 12:20:00.026 PM. It ran for 29 seconds and failed at 12:20:29.275 PM with Deadline Exceeded.. then it retried at 12:21:07.596 PM (37 seconds after failure): 02-22 12:21PM 07.596 /myTask 500 28548ms 306cpu_ms 160api_cpu_ms 2kb AppEngine-Google; (+http://code.google.com/appengine) E 02-22 12:21PM 36.140 class 'google.appengine.runtime.DeadlineExceededError': Traceback (most recent call last): File /base/data/home/apps/myApp/1.34005759049070 02-22 12:20PM 00.026 /myTask 500 29255ms 2777cpu_ms 193api_cpu_ms 2kb AppEngine-Google; (+http://code.google.com/appengine) E 02-22 12:20PM 29.275 class 'google.appengine.runtime.DeadlineExceededError': Traceback (most recent call last): File /base/data/home/apps/myApp/1.34005759049070 The general behaviour for my app is more like.. the task will fail, and then it will retry in 120 seconds (I have error logs showing this occurring back in February as well.) Maybe non-named tasks that are set to run immediately have retried on a different timeframe in the past.. but the retry time has not just been some generic sub-30 second time. As for Ikai's comment, it says what it says: The same task should not be executed multiple times concurrently. It does not say that the same task cannot be executed multiple times concurrently. Again, my money is on the reality that one cannot guarantee 100% that an error will never occur that could lead to concurrent task execution... you would cripple the task queu subsytem if you put in a bunch of preventative checks. Though, one can state with reasonable confidence that it is highly improbable that a task will execute concurrently. But, good luck getting a literal answer to your question.

I have been using the task queue since it was released, and definitely noticed tasks being executed more than once, but never concurrently. 1. I've had concurrent tasks execute at least once (that I noticed) when only one was supposed to run.. And, this appeared to happen when the subsystem first fired off the task (after it had already been added to the queue.. since TombstonedTaskError and TaskAlreadyExistsError seem to work nicely.). Well, from Ikai's comment it would sound like google does not expect this behaviour. I raised this thread through hypothetical analysis of the technology, but if you have seen it happen, then that is especially interesting. I personally can't see how it could legitimately happen if it backs off for more than 30s - it would be a bug in the system for the task to fire duplicates when it is first raised, IMO. How did you determine the execution was concurrent? 2. The GAE doc that I linked to explicitly states it is possible in exceptional circumstances that a Task may execute multiple times. I believe that this covers both cases of the same task running concurrently or sequentially. I don't think it does, but this is specifically the point of this thread - it is not clear. I don't want to engineer significant overhead into my application based on interpretation of unclear documentation. To me, the same task id executing at the same time in app engine, if it is possible, is something that needs to be explicitly documented, because it has significant impact on app architecture. Again, Ikai's comment above seems to imply Google does not expect this to happen. So if the documentation is unclear, and google seems to suggest the opposite of your interpretation, that's a good reason to be wary of the assumption you are making. 3.

The main issue is that most calls have to place two entries into the datastore: class PotMember(db.Model): pot = db.ReferenceProperty(Pot) member_id = db.IntegerProperty() count = db.IntegerProperty() second_pot = db.BooleanProperty() purchase_time = db.DateTimeProperty(auto_now_add=True) process_time = db.DateTimeProperty(auto_now=True) newMembers = [] newMembers.append(PotMember(pot=p, member_id=member_id, count=count, second_pot=False)) newMembers.append(PotMember(pot=p, member_id=member_id, count=second_count, second_pot=True)) db.put(newMembers) This operation takes ~300-400ms, which is enough for App Engine to complain that my application is executing too slowly and needs to be optimised. What exactly is taking so long to place these entries? Most other put() operations take ~10ms to complete.

[google-appengine] What are these logging metrics?
Hi All, We've been doing some performance testing with our app using JMeter and looking at our logs. If you expand a web call's log messages, at the top you see a bunch of metrics, e.g. ms=1332 cpu_ms=822 api_cpu_ms=86 cpm_usd=0.024510 Sometimes I see a metric 'pending_ms' but I can't find a definition anywhere. I assume it's some kind of latency. In the call I looked at all the logging messages occurred in the course of 300ms but there was a pending_ms=9800, so the reporting ms time was over 10 seconds. In this call there was no cold startup, I've also noticed a loading_request=1 when a request initiates a cold startup. I've also seen a metric, or flag, called throttle_code, that would be nice to understand. Anybody know what these are or where they are defined?

The limit of 10 applies to asynchronous urlfetches in a single request as describe here: http://code.google.com/appengine/docs/python/urlfetch/asynchronousrequests.html That being said, if a large proportion of your requests are making URLFetch requests and this causes your user facing round trips to be 800ms+, App Engine will not autoscale the number of instances you have running.

Re: [google-appengine] BUSINESS APP OR NOT?
Normal pricing. GAE4B pricing applies if you are writing an application that is only accessible for Google Apps (Gmail, Docs) users and not the general public. Here's an example: Google App Engine (current) You create an image sharing service anyone can use. Google App Engine for Business You create an expense reporting tool that you want tied to a specific Google Apps Domain, say, ikaicorp.com that only us...@ikaicorp.com can use.

However, it's still not performing particularly quickly and I'd like to speed it up a little more. The main issue is that most calls have to place two entries into the datastore: class PotMember(db.Model): pot = db.ReferenceProperty(Pot) member_id = db.IntegerProperty() count = db.IntegerProperty() second_pot = db.BooleanProperty() purchase_time = db.DateTimeProperty(auto_now_add=True) process_time = db.DateTimeProperty(auto_now=True) newMembers = [] newMembers.append(PotMember(pot=p, member_id=member_id, count=count, second_pot=False)) newMembers.append(PotMember(pot=p, member_id=member_id, count=second_count, second_pot=True)) db.put(newMembers) This operation takes ~300-400ms, which is enough for App Engine to complain that my application is executing too slowly and needs to be optimised. What exactly is taking so long to place these entries? Most other put() operations take ~10ms to complete. Is it the use of the DateTimeProperty or the use of the ReferenceProperty that is slowing this call down? Any help would be appreciated.

[google-appengine] Re: Idempotence multiple task execution
Thanks Eli - couple more comments below On Sep 9, 5:41 pm, Eli Jones eli.jo...@gmail.com wrote: How did I determine concurrent execution? I determined that I had concurrent task execution because you can see the task_name in the logs, and a named task successfully ran twice. And, the one that ran last threw a TaskAlreadyExists error when trying to add the next chained task to the queue since each named task has a specifically defined name for the next task in the chain and the version that finished first had already added the next named task to the queue. (This is why it is absolutely important to use named tasks when chaining.. some sort of random error can fork your tasks). I might have misunderstood something, but this example seems to only show multiple execution, not concurrent? Why do I suggest tasks do not just retry immediately (or in less than 30 seconds after failure).. and have done so in the time before your April 23rd e-mail. Well I guess our experience differs then. For me, it sometimes backed off for longer, but generally retried immediately, and frequently, until the backoff time reached a decent level. Way too much energy spent on it to forget it :) Here are some logs showing a task retry on Feb 22nd (it's hard to find many examples since Appengine Logs only keep error logs after a few months.. so I need to find two errors in a row for a task to see the retry). The task's first run was at 12:20:00.026 PM. It ran for 29 seconds and failed at 12:20:29.275 PM with Deadline Exceeded.. then it retried at 12:21:07.596 PM (37 seconds after failure): 02-22 12:21PM 07.596 /myTask 500 28548ms 306cpu_ms 160api_cpu_ms 2kb AppEngine-Google; (+http://code.google.com/appengine) E 02-22 12:21PM 36.140 class 'google.appengine.runtime.DeadlineExceededError': Traceback (most recent call last): File /base/data/home/apps/myApp/1.34005759049070 02-22 12:20PM 00.026 /myTask 500 29255ms 2777cpu_ms 193api_cpu_ms 2kb AppEngine-Google; (+http://code.google.com/appengine) E 02-22 12:20PM 29.275 class 'google.appengine.runtime.DeadlineExceededError': Traceback (most recent call last): File /base/data/home/apps/myApp/1.34005759049070 The general behaviour for my app is more like.. the task will fail, and then it will retry in 120 seconds (I have error logs showing this occurring back in February as well.) Maybe non-named tasks that are set to run immediately have retried on a different timeframe in the past.. but the retry time has not just been some generic sub-30 second time. As for Ikai's comment, it says what it says: The same task should not be executed multiple times concurrently. It does not say that the same task cannot be executed multiple times concurrently. Again, my money is on the reality that one cannot guarantee 100% that an error will never occur that could lead to concurrent task execution... you would cripple the task queu subsytem if you put in a bunch of preventative checks. Though, one can state with reasonable confidence that it is highly improbable that a task will execute concurrently. But, good luck getting a literal answer to your question.

I've had concurrent tasks execute at least once (that I noticed) when only one was supposed to run..

I raised this thread through hypothetical analysis of the technology, but if you have seen it happen, then that is especially interesting. I personally can't see how it could legitimately happen if it backs off for more than 30s - it would be a bug in the system for the task to fire duplicates when it is first raised, IMO. How did you determine the execution was concurrent? 2. The GAE doc that I linked to explicitly states it is possible in exceptional circumstances that a Task may execute multiple times.

I deployed a sample application and the cold starts were taking almost 30 seconds, so I figure that once I add more code to it, cold starts will take longer than the 30 second deadline. So if that feature will be coming out within the next 3 months or so, I figure I'll go with Grails, if not, then I'll do something else. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Question about sort order on id on entities of the same kind but having different parents
Hi All, I think I know the answer to this but I'd like someone from the app engine team to provide a definitive answer if possible. When querying on a single entity type where the result set contains instances of entities that are children of different parents (thus belonging to different entity groups) will ordering on their ids though specified be ignored? My instinct tells me that ordering will be ignored. In other words, is the rule then the following: Ordering is allowed on key ids only if all entities have the same kind _and_ parent In addition, I would also assume that filtering works the same way, having the same restriction. Correct? Thanks in advance for your response. -- -- Jeff -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Cron Job and Cursors
Hi, I have a very basic problem. Below is my model: class DummyModel: id:Integer info:Integer added:DateTime What I need to do is to have a cron job running per day to filter on added field and do something with the info field, but I have many entities and I want to make this process in batches maybe continue another day. How to do that efficiently? Cursors? Can we use them with cron jobs? Any example suggestion would be appreciated.

[google-appengine] Re: Python 50% faster than Java
The author of this article just underqualified. For example: So I took to writing the service in Python. I quickly realized that Python had much more control over the datastore. It was really easy to pick which fields to index and which fields to ignore. In Java, all fields were indexed. He even don't know how to make unindexed property in Java. About Java GAE low-level API or about Objectify he probably know nothing.

[google-appengine] Re: Python 50% faster than Java
I think 4 cases that can depend on context makes ambigiously 1) A is a faster interpretator than B 2) A is a faster VM than B 3) Specific solution with A is faster than with B 4) Development times are much quicker some way compared to other less regarding execution time Cheers Nick Rosencrantz On Sep 10, 3:11 am, Dmitriy T. 403...@gmail.com wrote: The author of this article just underqualified.

Re: [google-appengine] Cron Job and Cursors
What is many entities, is it 100, 1,000, 1,000,000, more? What are you doing with the info field? Are you aggregating something? Transforming it? Writing one new model for each entity? What do you mean continue another day? Do you mean process some entities then stop and continue processing on another day?
