Re: [google-appengine] Strange import errors in logs (fatal)
Pamela, Specifically Takashi is probably asking if you have any naked except blocks: try: # Do something except: # Do a dance People often do stuff like: try: import json except: import simplejson If you have some of these, then you could be catching DeadlineExceededErrors that occured (they can occur basically anywhere on appengine). The instance should get killed if one of these errors occurs but it's best to handle it correctly in your code. That kind of thing can cause problems. You need to do this instead. try: ... except Exception: ... Some libraries are known to have these kinds of try except blocks. Older versions of Jinja2 and werkzeug for example.

[google-appengine] Kay 1.1 final released!
Hi everyone, We just released Kay 1.1 and 1.0.1 final! Kay 1.1 is the next minor release of the Kay Framework for Appengine. It includes new features as well as bug fixes. Kay 1.0.1 includes bug fixes in Kay 1.1 backported to the 1.0.x branch of Kay. It is for users of Kay who do not want to upgrade to the new version and would prefer to only upgrade to fix bugs and avoid backwards incompatibility problems. Kay 1.1 release doesn't include any backwards incompatible changes but has some loud warnings for several deprecated features based on Kay's deprecation policy: http://code.google.com/p/kay-framework/wiki/ReleasePolicy#Minor_releases See Kay's deprecation timeline here: http://code.google.com/p/kay-framework/wiki/KayDeprecationTimeline Download the new releases here: http://code.google.com/p/kay-framework/downloads/list Please test and file bugs here: http://code.google.com/p/kay-framework/issues/list You can see the release notes for both releases here: http://code.google.com/p/kay-framework/wiki/ReleaseNotes Changes in 1.1 * Improved exception and error handling. * Added a new kay.ext.ereporter application for managing error reporting. * Added a new kay.ext.live_settings application for managing global settings without having to reploy. * Added a new AppStatsMiddleware? which can be used to enable appstats. * Added a new Pagination API * Added the COOKIE_SECURE setting to support secure session cookies ( Issue #90 ) * Added a new timezone_functions context processor. * Added a new cron_only view decorator for securing cron views. * Lazy load jinja2 so that requests that don't require jinja2 can return faster. * Updated google SDK taskqueue imports to import from the new package name. * Fixed an issue where the django module could not be loaded. Changes in 1.0.1 * Fixed an issue where error mails could not be sent to email addresses that were not specified as a developer in the admin console. ( Issue #50 ) * Fixed an issue were the django module could not be imported after upgrading to the Appengine SDK 1.4.2 ( Issue #92 ) * Fixed an issue where kay returned instances of the InternalServerError? exception rather than an object that subclasses BaseResponse? ( Issue #54 ,#56) * Fixed an issue with the remote API and the HR datastore. * Updated imports to the taskqueue API so they use the new import path ( Issue #73 ) Happy Coding!! -- Ian http://www.ianlewis.org/ -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] High Replication or Master/Slave?
Hi, I think that the Appengine team is recommending that folks use the HR datastore for new applications. That said the only benefit seems to be that you can write to the datastore even during maintenance so if that is not important to you, and your data is likely to be very large then master/slave might be a better choice. If I were you I would probably go with HR.

On the contrary the Master/Slave is faster which is important to me. Basically, what is the opinion of people who have used both in a production environment? Should I stick with Master/Slave or make the change before it's too late? Thanks -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Google App Engine datastore supports only 200 indexes..
Hi, The number if indexes isn't affected by the number of properties on an entity. It only has to do with the number of indexes for complex queries that are needed in your application (i.e. Those in index.yaml). So the number of indexes created automatically (by properties on indexes) are probably only limited by your available storage and doesn't limit the number of entities or properties on entities.

Re: [google-appengine] Re: memcache.flush_all() failed without error
Speaking from experience, when the datastore is in maintenance mode, memcache has also always been in maintenance mode. Given that it supports namespacing the same way the datastore does and is almost always in maintenance mode at the same time it's likely that memcache is tied to the datastore in some way. That said they may only put one in maintenance so the only way to really check is to use the capabilities API. http://code.google.com/intl/en/appengine/docs/python/capabilities/overview.html Ian On Sat, Feb 26, 2011 at 9:35 PM, pdknsk pdk...@googlemail.com wrote: I meant the other way around: scenario where memcache is in maintenance but database isn't. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

If the task is guaranteed not to be duplicated then I could use the time the task was to be run in the name and calculate that in the cron job. A bit fragile but doable.

[google-appengine] Chaining tasks forever and checking enqueued tasks
Hi all, I've written an application that does some work every X minutes/seconds for each entity of an entity type in the datastore. Currently this is done by running an cron job and calculating the next runtime for each entity and enqueing tasks with delays so that they are run at the appropriate time. But it's hard to be flexible about the interval that tasks can be run when the cron intervals are hard coded. Also, cron sometimes fails to run and I'd like the application to be more robust. It would be easy to chain the tasks for each entity forever and simply not run and die if the entity is removed from the datastore, but I'm worried about a situation where the task would get dequeued for some reason. In that case all subsequent tasks for that entity wouldn't be run. I'd like to combine the task queue and cron and chain tasks but have cron check every so often to make sure the tasks are still enqueued. Is there a way for the application to check if a task is enqueued in the task queue? -- Ian http://www.ianlewis.org/ -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Datastore
Ben,
With non-relational databases like appengine's datastore you need to
create data based on the way you will query it rather than the way you
want to store it.
In your case it looks like you would need to create a model to store
the data you want to query (essentially an index that you manage). A
model something like the following might work.
PeopleOwnItemsIndex {
person (reference to the person owning the items/people)
owner (reference to the person owning the item)
item (reference to the item owned)
}
You'll be querying on the person field so the query will need to go in
your datastore-indexes.xml or index.yaml
When you change owners or add items you'll need to update the data for
this model. If you want to consolidate models you could also get only
your own items by creating an index on person+owner and query it with
person = me, owner = me. That would be instead of using PersonOwnItem,
but the difference would be you would have a record for each person
that can see the item rather than only one for the person owning the
item.

basically a hierarchy of ownership.
The 2 base tables:
table People {

table items {
int itemId;
string itemName;
}
The 2 relational tables:
table PeopleOwnPeople {

table PeopleOwnItems {

So now that we have a basic structure I can start to explain the idea

the people i own:
select items.* from Items, PeopleOwnPeople, PeopleOwnItems where
(PeopleOwnPeople.ownersId=234 and
PeopleOwnPeople.personId=PeopleownItems.personId) or
PeopleOwnItems.personId = 234 ;
I am looking to use GWT as my frontend to this project so I am likely
going to be using Java for the backend but that isn't set in stone
yet.
Thanks any and all help.

Re: [google-appengine] When chaining tasks with the task queue, what if one task fails before queuing the next task?
Ryan, Tasks are repeated until they return a HTTP success code. So your task need to be indepotent in that if they should still do the right thing (not write things twice etc.) if your task gets run more than once because of failure. So if one task in the chain has an error, then that task will be run again and can complete the chain. You just have to make sure that if it runs twice, it can continue processing where it left off.

Andy, I believe the project's goal was to support django 1.0 on appengine but since 1.0 is now available there isn't much point to continuing the project.

[google-appengine] Re: Fetch with limit returning more results than limit
Ben,
It looks like filter will add a filter to the existing query object (instead
of creating a new query object like django does) but the fetch method will
retrieve the objects and return them immediately without modifying the
query. You should do something like:
items_list = items.fetch(10)
and then pass the items_list to your template.

when i iterate through the results via django in the template it

is returning all results that meet that criteria instead of just the

[google-appengine] Smipple - Social Code Snippets
Hi all, I just wanted to let everyone know about a site I created for sharing code snippets in a social way. You can check it out at http://www.smipple.net/. Smipple allows you to save, organize, and share snippets with others easily. The best part though is that you can follow other people who have interesting snippets and see the snippets that users you are following in one place. You can also favorite any snippet that you find interesting so you can retrieve it easily later. Smipple is implemented using Google Appengine, Django, and appengine-patch but that shouldn't stop anyone from contributing any kind of snippets that they want. We'd love it if Ruby, PHP, Java, JavaScript or Perl developers would use the site as well! What kind of social sharing site would it be if there were only certain types of developers using it after all!

[google-appengine] Re: best away to know numbers of rows in a entities
If you used numeric keys then you can do pagination by key in order to get all items from the datastore and count them. Basically this involves querying the datastore several times, each time filtering on keys that are greater than the highest key from the results of the previous query. You won't want to do this often as it will likely take to long to do it in a single request so you'll probably only want to do it once and store the value in a counter for later use. If you are using key names and don't have a way of pulling unique data, say via a create time DateTimeProperty, then I'm afraid you're kind of out of luck. You could try different filters and pull the data locally and compare the keys to get unique entities but that sounds like a serious pain. Someone else might have a better idea in this case.

[google-appengine] Re: How do I limit searchable_text_index using SearchableModel?
ogterran, It should do one for the search and then one for each item in the search result. If you are worried performance on the calls to the datastore you can modify this code to make the ProductSearchIndex entity be a child of the Product entity and use a key only query to retrieve only the keys for the search index entities (since we only really care about the Products anyway). This will still to the same number of queries but will avoid the overhead of deserializing the ProductSearchIndex objects (and the associated index list property which might be long). Something like the following should work: class Product(db.Model): pid = db.StringProperty(required=True) title = db.StringProperty(required=True) site = db.StringProperty(required=True) url = db.LinkProperty(required=True) class ProductSearchIndex(search.SearchableModel): # parent == Product title = db.StringProperty(required=True) ... # where you write the Product product = Product(pid = pid, title=title, site=site, url=url) product.put() index = ProductSearchIndex(parent=product, title=title) index.put() ... # where you search keys = ProductSearchIndex.all(keys_only=True).search(query).fetch(100) for key in keys: product = Product.get(key.parent()) print product.url On Tue, Jun 23, 2009 at 5:59 PM, ogterran jonathanh...@gmail.com wrote: Hi Ian, Thanks for the response.

Not quite - it will do one _query_, and multiple gets. A get is much, much cheaper than a query. You're right about the number of round-trips, though. If you are worried performance on the calls to the datastore you can modify this code to make the ProductSearchIndex entity be a child of the Product entity and use a key only query to retrieve only the keys for the search index entities (since we only really care about the Products anyway). Good idea! This will still to the same number of queries but will avoid the overhead of deserializing the ProductSearchIndex objects (and the associated index list property which might be long). Something like the following should work: class Product(db.Model): pid = db.StringProperty(required=True) title = db.StringProperty(required=True) site = db.StringProperty(required=True) url = db.LinkProperty(required=True) class ProductSearchIndex(search.SearchableModel): # parent == Product title = db.StringProperty(required=True) ... # where you write the Product product = Product(pid = pid, title=title, site=site, url=url) product.put() index = ProductSearchIndex(parent=product, title=title) index.put() ... # where you search keys = ProductSearchIndex.all(keys_only=True).search(query).fetch(100) for key in keys: product = Product.get(key.parent()) print product.url This can be done much more efficiently: keys = ProductSearchIndex.all(keys_only=True).search(query).fetch(100) products = db.get(x.parent() for x in keys) Now you're down to just two round-trips! -Nick Johnson On Tue, Jun 23, 2009 at 5:59 PM, ogterran jonathanh...@gmail.com wrote: Hi Ian, Thanks for the response.

[google-appengine] Re: Low Overhead CapabilityDisabledError Check
Greg, Please star this issue. http://code.google.com/p/googleappengine/issues/detail?id=1116 One person noted in the comments that you could cache a system wide value when the first put request fails so that you don't have to do a test put() on every request to your application. It would be interesting if run_in_transaction throws this exception even with dummy functions but I would guess that it doesn't throw the error unless it actually tries to a write.

This will run on every request, so it would be good to use as lightweight a check as possible. The documentation says CapabilityDisabledError is thrown by db.Model.put(), db.Model.delete(), and db.run_in_transaction(). My question is this: can I use run_in_transaction() with a dummy function - testing without the overhead of actually doing a put()? I realise that in this case memcache is also being disabled, so I can test by doing a memcache.set() instead, but it would be nice to develop a function that can be called to test both, for cases when maintenance only affects one or the other.

[google-appengine] Re: Uneven response time between connection to server to first byte sent
Anders, For ajax calls you might consider creating a very simple handler that uses as few modules as possible when performing ajax calls. Then put that as a separate url in your app.yaml. In that case appengine would only load the modules it needs to serve that request and would hopefully not take as long (as say to load a whole framework like django). That might help reduce the latency of some of your ajax calls. Ian On Mon, Jun 8, 2009 at 3:04 PM, Anders i...@blabline.com wrote: Ok, just one more comment. Both serious and tongue-in-cheek style. To use a metaphor, I hope that Google App Engine will become like a real car and not be a plastic toy car for kids. Maybe someone from Microsoft or Amazon has managed to infiltrate the management of App Engine at Google. Not only do (did) the sometimes exceedingly long start-up times for application instances suck, there is also (at least was) a lack of clock synchronization between GAE servers. This means that an application like Twitter is not possible to implement using Google App Engine. For example, the Twitter API allows max 50 something calls per minute in some cases.

Issac,
You cannot include a space after the | for filters. Try {{ event.code|escape
}}.
BTW: django does auto-escaping and you shouldn't need the escape filter
unless you have turned auto-escaping off. Turning auto-escaping off is
something I personally wouldn't recommend.

Hi folks,
I put this in a template file

From what I gather, escape is supposed to be built in to Django 0.96
templates, so it seems like this should work. Have I left something out?

Any thoughts on this? Why would the cron job be blowing up on import?
Have I set something up wrong? The development environment doesn't

class 'google.appengine.ext.db.KindError': reference_class must be
Model or _SELF_REFERENCE
Traceback (most recent call last):
File /base/data/home/apps/rcapp01/1.333786861669922384/cron.py,
line 1, in module
from callme.models import CAction
File /base/data/home/apps/rcapp01/1.333786861669922384/callme/
models.py, line 9, in module
class CUser(db.Model):
File /base/data/home/apps/rcapp01/1.333786861669922384/callme/
models.py, line 11, in CUser
user = db.ReferenceProperty(User)
File /base/python_lib/versions/1/google/appengine/ext/db/
__init__.py, line 2577, in __init__
raise KindError('reference_class must be Model or
_SELF_REFERENCE')
The code in question deals with the ReferenceProperty that I am using
to extend the basic django user. The code for that looks like this:
from google.appengine.ext import db
from django.contrib.auth.models import User
# Create your models here.
class CUser(db.Model):
user = db.ReferenceProperty(User)
I don't seem to have much problem interacting with the profile through
the web requests, but when the cron job tries to run it blows up. I am
not going to include the cron job as you can see that the traceback
happens on the import.
Any thoughts on this? Why would the cron job be blowing up on import?
Have I set something up wrong? The development environment doesn't
seem to blow up when this happens.
Thanks in advance.

[google-appengine] Re: Not working app-engine-patch-sample-1.0 sample application
You will need to provide a way for appengine to email to your e-mail account if you want to be able to have it send e-mail to you. This is done by providing the information about your SMTP server in the settings.py or by passing the --enable_sendmail or --smtp_host, --smtp_port, --smtp_user, and --smtp_password options to manage.py runserver. --enable_sendmail will only work if you have sendmail on your machine obviously. Setting the email options in your settings.py looks like it does in django: EMAIL_HOST=localhost EMAIL_PORT=25 EMAIL_HOST_USER= EMAIL_PASSWORD= I'm really not sure how well setting the smtp options work as I use the sendmail option locally. I do know there was an issue with setting the SMTP options on linux. http://code.google.com/p/googleappengine/issues/detail?id=626q=smtpcolspec=ID%20Type%20Status%20Priority%20Stars%20Owner%20Summary%20Log%20Component On Fri, May 29, 2009 at 10:11 PM, S K sksk...@gmail.com wrote: Hi All, can any one tell that in this link * http://code.google.com/p/app-engine-patch/ *one sample application( *app-engine-patch-sample-1.0*) , I have downloaded and run the application but in that registration for after enter all the field and submit the but is saying that *In order to activate your account please check your email and click on the activation link.* but I haven't received any mail to activate my account, If any one helps means its useful for my coding, kindly help me on this, its urgent for me Thanks in Advance Regards SK -- === 株式会社ビープラウド イアン・ルイス 〒150-0012 東京都渋谷区広尾1-11-2アイオス広尾ビル604 email: ianmle...@beproud.jp TEL：03-5795-2707 FAX：03-5795-2708 http://www.beproud.jp/ === --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

Otherwise, if it were that trivial Google could've provided that feature a long time ago. I could imagine that if you used a script to remotely update the search index you could actually get acceptable search performance (i.e., on the already-built index), but I don't have any hard numbers here and Shay Banon didn't know if the port would perform well on App Engine, either.

Tom, You can't use the remote api from appengine. It's for use in accessing the data from applications outside appengine.

[google-appengine] Re: Deleting CounterShards
Bill, The docs say otherwise. count() on a query object returns a maximum of 1000. http://code.google.com/appengine/docs/python/datastore/queryclass.html#Query_count Sharded counters are used to ease contention for highly updated objects but that doesn't downplay the need for counters. You need to either put a counter on a separate entity or create sharded counter if you want to count more than 1000 entities. Ian On Mon, Mar 2, 2009 at 5:40 PM, Bill billk...@gmail.com wrote: You can count well over 1000 objects -- the limitation is in the fetching, but that's not the reason for sharded counters in Bloog. I wrote Bloog way back when App Engine was new and I was trying out different best practices for datastore ops. Sharded counters are a way to handle heavily-used counters, e.g. if the counter was getting updated dozens of times per second. If you have that many increments/ decrements on a counter, if you put the counter in a single integer property, you'd start getting write contention. In retrospect, doing the sharded counter in Bloog was complete overkill. It was useful to me at the time, because I was learning. But the next version of Bloog will likely use a single integer property for the counter and scrap the sharded counter. -Bill On Mar 1, 9:11 pm, Ian Lewis ianmle...@gmail.com wrote: Krishna, The datastore can only return or count up to 1000 objects so if you have more than 1000 objects in the database you cannot count them without a counter.

[google-appengine] Re: Deleting CounterShards
Krishna, Anything you see in the data viewer is created by some application code. It wouldn't be put there by google appengine specifically. That said it looks like something is using a sharded counter to keep counts of objects in the datastore or something similar. This data would not likely be regenerated if deleted, it would likely reset all the counters to zero so I would leave it alone.

[google-appengine] Re: Deleting CounterShards
Krishna, The datastore can only return or count up to 1000 objects so if you have more than 1000 objects in the database you cannot count them without a counter. I assume the code in Bloog is keeping counts of objects in case it runs up against this limitation.

So I'll trust your cautious approach although I don't quite understand why something would need to keep counts of objects in the datastore.

image = db.BlobProperty(required=True)
mimetype = db.StringProperty(required=True)

if not request.user.use_gravatar and 'profile_image' in request.FILES:

old_profile_image = UserProfileImage.all().filter('user =',
request.user).get()
uploaded_file = request.FILES['profile_image']
# There should be only one chunk as we can only upload to memory

[google-appengine] Entity Groups
Hi all, The documentation seemed to suggest that the more root entities you have the more it can distribute your query so it should be faster, but I'm curious about entity groups and what, if any, advantage there is to putting entities in an entity group besides being able to use them in a transaction. Is there any? Ian --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Problem with models Google App Engine Helper for Django
cw, What's the directory where models.py with your Quiz model in it? More accurately what is the python module with your Quiz model in it? 2009/2/3 cdub carl...@gmail.com I have my application up and running with the Google App Engine Helper for Django. But when I went to add a simple model: models.py -- from appengine_django.models import BaseModel from google.appengine.ext import db class Quiz(BaseModel): question = db.StringProperty() I started getting the following error: IndexError at / list index out of range Request Method: GET Request URL:http://localhost:8080/ Exception Type: IndexError Exception Value:list index out of range Exception Location: /Users/carlin/Documents/Personal/Programming/ mysite/appengine_django/models.py in __init__, line 51 Any ideas?

[google-appengine] Re: The API call datastore_v3.Delete() required more quota than is
You likely need to wait a day or so to have the quotas reset themselves. It
looks like you using too much of one of the appengine quotas.

Correction, it's datastore_v3.Get() not Delete()

I've ran into the error The API call datastore_v3.Delete() required

What I'm doing is using the bulkload_client.py to load 4 entities at a
time.
eg. INFO 2009-02-03 01:03:42,049 bulkload_client.py] Importing 4
entities in 953 bytes
After ~174 such imports, I get the quota error.
The loader HandleEntity is doing the following:
1) lookup an entity A by key name
2) delete entity A if found
3) lookup an entity A by another key name
4) create a SearchableEntity based on the entity
5) lookup an entity B by key name
6) update entity B if found and put() it
7) lookup an entity C by key name
8) update entity C if found and put() it
9) return the SearchableEntity

[google-appengine] Re: Problem with models Google App Engine Helper for Django
Yup,
The appengine_django/models.py has a funny little piece of code that
requires your models module to not be a top level module.
class ModelOptions(object):
...
def __init__(self, cls):
self.object_name = cls.__name__
self.module_name = self.object_name.lower()
model_module = sys.modules[cls.__module__]
self.app_label = model_module.__name__.split('.')[-2]
self.abstract = False
The fourth line of __init__ there breaks if you have a modules with models
in a top level module. Go figure.

Hi Carlin,
Carlin Wiegner wrote:
Right now my models.py is in the root directory of mysite.
As I believe Ian was hinting at in his response, the helper (and Django)
expect your models to be within a Django application (basically a
subfolder) of your Django project (your Django project == your App
Engine application, confusing I know ;p).
So you need to create a directory, say called myapp and place your
models.py in that (don't forget to also add __init__.py). Then you list
myapp in the INSTALLED_APPS section of settings.py and you should be
good to go.
Cheers

[google-appengine] Re: Why Google App Engine is broken and what Google must do to fix it.
The documentation says that an entity group could be as large as a single user's data. It seems to me that to avoid the problem you are describing that it would be a good idea to do so. I have a feeling that the number of cases where you would need to update more than one user's data in a single transaction would be limited. 2008/10/8 Josh Heitzman [EMAIL PROTECTED] Assuming you can actually work around all of the limitation simultaneously, considering the more things you work around the close you come to the CPU time quota. It also is not completely accurate to state that the limitations are there to make apps safe and scalable. For example transactions being limited to a single entity group makes it very complicated (i.e. not safe) to write code that needs to reliably update entities from different groups (it isn't always possible to structure entity groups such that everything that is needs to be updated for a request can be all be in one entity group). Also given the roundness of the quotas, I find it very unlikely that the quota numbers were choosen based on an in depth analysis or a broad sampling of data, rather the being choosen fairly arbitrarily (possibly based to some extent on what works for google's own apps). On Oct 7, 4:16 pm, Greg [EMAIL PROTECTED] wrote: Davew said it way back at the top - appengine's killer feature is scalability. That is what sets it apart from the other cloud systems out there, and it is also the root cause of most complaints (except the quotas, which will disappear when you get to pay for the service). For the application I'm working on, I'm happy to trade off lack of a relational database for the future gain of scalability. My guess is that most of you haven't had the nightmare of an application that suddenly became popular, and you had to become an expert at database replication, load balancing and multi-system maintenance overnight. It's a very stressful situation. So my advice is that if you don't need scalability, get a normal hosting account or EC3. Then you can have PHP, Ruby, MySQL, cron jobs, anything you want - problem solved. Oh, yes you are going to have to shell out a few buck a month. But if you do need scalability, then appengine is a godsend. The limitations are there to make it safe and scalable, not because Google wants to annoy you. You spend a little more time now working around the limitations, and save endless time later managing systems and capacity. And lastly, I believe that many of the complaints come from people just wanting a free hosting service, and not finding what they are used to. It would be a crying shame if Google listened to these people and turned appengine into a vanilla PHP/MySQL hosting service. Appengine is so much more...

If Google App Engine is to succeed it is what the customers want. If it is designed as you have stated it will never recoup what Google has spent so far let alone down the road. Google App Engine has so many many limitations. Regardless if the limitations are by design or not it is virtually unusable by 99% of all developers. Can Google make a business off the remaining 1%? The question of whether Google can turn Google App Engine into a profitable business doesn't depend on what percentage of developers find it useful, but whether Google exploit a competive advantage. Google could've started up a tradtional web hosting service using popular SQL databases and other techonologies and created something that would have had a much broader appeal. Any one could. That's the problem. Google might be able to grab market share, but without anything to distiguish themselves from their competitors, a best they only get a marginal return on their investment. We can only speculate on what Google business plan for GAE is, but it seems pretty obvious to me that leveraging Google's own internal technologies is at the heart of it. A number of limitations and problems with GAE stem from technologies like Big Table, Google Frontend and Google Apps. Another part of their plan appears to be keeping support costs low, so you're not given much rope to hang yourself (or others). If, in the long term, Google can't make a business following this plan, if it doesn't give them enough a competive advanage, then there's probably no way they can make the kind profits from a hosting service that Google's investors expect. (While it's not terribly relevent to this discussion, I suspect Google has some other goals for GAE that don't deal directly with its viability as a business. One is to educate programmers in the Google way of doing things. I'm sure Google has been fustrated with tons of
