[appengine-java] Application works fine on localhost but not when deployed

2010-10-12 Thread swin swin

Hi,

I keep having the same problem of not being able to get my application
to work when deployed on GAE. It works fine locally on my laptop when i
run it with the google app engine server. Online, I am able to view
a 'login.jsp' page, but when I try to login as an authenticated user,
it will return a 500 Server Error. However, if I try to login using a
wrong user/password, it would return fine and say that there is an
error. I suspect that the problem lies with my homepage.jsp, which an
AuthenticateServlet of mine sendRedirects to.

Really hope someone can help me solve it. Has been bothering me very
much. Appreciate any help!

The error logs are as such:

Re: [appengine-java] Is MemcacheService obtained from getMemcacheService(namespace) thread safe?

2010-10-12 Thread Maxim Veksler

Great, thank you for clarifying this.

Perhaps It would be helpful to mention this in the javadoc ?
Or maybe introduce some kind of @ThreadSafe annotation
with RetentionPolicy.SOURCE ?

Thanks,
Maxim.

If you're really worried about this, you don't really save much by doing
this, however, since the only real cost is object allocation.

AFAIK you have two different behaviors on purpose. The idea is to
allow anybody in your local environment, but require a proper OpenID
account for your site.

This means that you will have to test the OpenID behavior online or
invoking directly _ah/login_required

[appengine-java] Re: GAE and Log4j - A little solution to make things easier.

2010-10-12 Thread Nacho Coloma

JUL has been reported as 60 times slower than other implementations
because of the way they log:
http://www.infoq.com/news/2007/08/logback

Just configuring properly log4j/logback to log to System.err or
System.out should be enough to see messages properly in the AppEngine
console. In logback, it's something like this:

appender name=STDOUT class=ch.qos.logback.core.ConsoleAppender
encoder
pattern%-5level %logger{0} - %msg%n
/pattern
/encoder
filter class=ch.qos.logback.classic.filter.LevelFilter
levelERROR/level
onMatchDENY/onMatch
onMismatchACCEPT/onMismatch
/filter
/appender

appender name=STDERR class=ch.qos.logback.core.ConsoleAppender
targetSystem.err/target
encoder
pattern%-5level %logger{0} - %msg%n
/pattern
/encoder
filter class=ch.qos.logback.classic.filter.LevelFilter
levelERROR/level
onMatchACCEPT/onMatch
onMismatchDENY/onMismatch
/filter
/appender

root level=DEBUG
appender-ref ref=STDOUT /
appender-ref ref=STDERR /
/root

Then, you can use slf4j-jcl to redirect also your commons-logging
messages.

 Hey,

 I've written a Log4j appender which passes on log4j severity levels to
 GAE's JUL framework so you can view your log4j events (or the events
 your chosen framework provides) if you need to.

 This is a quick implementation of this Appender for me and so far it
 works, but I'd love to hear some feedback about what it doesn't do (or
 doesn't do properly) as I've not used it in anger.

[appengine-java] Configuring AName

Hi everyone,
I want allow the user of my site to have user pages with urls like:

http://username.mysite.com

To do this on GoDaddy I need to configure the Aname to star (*), but I
can do this only if I have an IP address.
I tried to ping ghs.l.google.com and I retrieve the ip address: 74.125.43.121.
I tried to map star(*) with this ip address, but I receive a page with
the following error: The requested URL / was not found on this
server.

somebody can help me?

imho you can associate domains with your app only through the appengin
admin interface.
from your email i guess you try to make a subdomain per user
registered with your site.
that would be great, but i don't think it will work.

[appengine-java] Re: ClassCastException: String to Collection

2010-10-12 Thread decitrig

I may have stumbled across the answer by commenting out fields one at a
time. Vendor had an embedded class PremiumInfo that referred to a
non-embedded class Review. When I either a) removed the Review field
from PremiumInfo or b) made PremiumInfo not embedded, the problem went
away.


Is having an embedded class owning a collection of non-embedded classes
a no-no?

[appengine-java] Re: OneToOne relationship with java.lang.Long ids

2010-10-12 Thread curti...@gmail.com

 The ID for the owned child User instances has to be a Key or String type 
 because the it contains both the reference to the parent(s) and the unique id 
 of the object.  A Long alone will not contain enough information to navigate 
 the object model to it.

That statement doesn't make sense to me. The relationship from Event -
 User is uni-directional so it isn't necessary to have a link from
User back to Event.

 You can create/encode/decode Keys easily using the KeyFactory.
I want to create a portable JPA domain model and that is why I coded
my model as such. I would like the option to be able to move this
model from GAE over to MySQL... so I don't really like the requirement
to use a String key either.

Perhaps this information need to be added to the unsupported features
section? (Long ids and relationships don't play nicely.)

Thanks,
Rick

[appengine-java] Implementing inequalities with multiple properties.

I have a requirement to make searches with inequalities with multiple

This is not possible, as described in

But I have to do it anyways. So, is there any hint on how to deal with
this? I think many people has faced this problem.

Re: [appengine-java] Implementing inequalities with multiple properties.

2010-10-12 Thread Cyrille Vincey

My workaround (I'm doing the testing so far) :
- create a extra property that merges the content of the N properties you
wish to filter on
- query on that single extrat property with inequality filters

That is what geohash does when merging latitude AND longitude into one
single property :

Re: [appengine-java] Problem with large entities? Store in one or two separate entities

2010-10-12 Thread Ikai Lan (Google)

If it's a few small fields, I don't think the performance difference is
worth the extra complexity. The size of the entities does have an impact on
the overall performance of the fetch, but there difference is usually more
material if each entity stores a few hundred kilobytes of data.

General question - If I have very large entities with information that

I'm creating fairly large entities (column wise) and was wondering what the
proper strategy was to approach storing the properties. An example is, I'm
creating profiles for people. This includes basic information like name,
email, url, but also information like bios, interests, affiliations. 90%+ of
the time I will not need the bios/interests/affiliations, just the
name/email/url. Should I be splitting the larger blocks of information into
another entity, and rather than just have a Person entity, instead have a
Person entity AND a PersonDetails entity?

I arrived at this concern when I was doing queries, and I fear that with
loading larger entities I'm consuming too many resources getting each
property. Is this something I should be concerned about? Or just query large
entities and it won't matter.

[appengine-java] Re: Google App Engine MUD

2010-10-12 Thread 番頭Fattom

What you want is An Easy Version MUD or Complete Version MUD?

If you want to hardcode all the thing, you only have to know what is
AJAX.
It's easy.

But if you want to implement a real MUD, Complete Version MUD, you
have to know a lot of things. ex: how to write a compiler...
Because MUD is including MUD OS and MUD Lib.
You have to make a wizard to make Object on your platform, by
coding !!
For example a wizard can create Car to be Driven or Horse to be
Mounted.. because your MUD OS support User, Entity and Action.
Car is Entity.
Drive is Action.
And User can Action the Entity
So User can Drive Car, and Mount the Horse.

But what kind of the Car?
Super User in the MUD (King or Admin) can describe what's the car,
Toyota, BMW...


But you can hardcode all of that.

FYI: http://www.mudos.org/

 Thanks for your response. I don't think most browsers support

 What is the most challenging part of writing a MUD for http aside from

 I believe I can write the methods required to produce the output that
 is expected from the various commands in the game I plan to implement,
 and can manage player attributes with player objects and back them
 with a nice database.

 I could certainly be missing something crucial though, so please let

   My friend and I are looking to rewrite an old BBS MUD.

   The game is a few thousand rooms and purely text based with commands
   issued by individual players and the game responding and updating
   players stats based on the results of their commands.

   I do not have a programming background, and I'm wondering about the
   best way to approach writing it for GAE.

   Attempting to translate the game to objects, I have the following
   layout:

   World object holds all of the zone objects, zone objects hold rooms,
   room objects hold players, player objects hold inventory objects,
   spellbook objects, and attributes. Then write appropriate methods for
   manipulating the objects appropriately and returning the results.

   I have a few questions though:

   1. Is this a technically correct way of approaching the problem? If
   not, what would be better? (keep in mind, I am not a professional
   programmer by any means. I can find my way if I have something already
   written to make changes, but I've never written anything from scratch
   before). Would I populate all these objects, then write world to the
   db and retrieve it for each player action? I have no idea how servlets
   work to store state, or really how they work in general really.
   Basically, how would I be storing and retrieving stored player
   statistics which are constantly changing many times a second as
   players play the game.

   2. A key issue is the ability to push updates to players in real time,
   and track individuals who are connected. For example, I would like the
   ability to be able to call something like
   room[someroomnum].sendtoall(Some message here); to push a message to
   all players in that room, or player[someplayernum].send(some message
   here); to send replies to players directly.

   I understand this is a complex issue with the stateless http protocol,
   but I have read some about the upcoming channel API which sounds like
   it may offer this ability but I don't know enough to be certain.

   Overall I'm looking to avoid devoting countless hours to this project
   if it is going to be beyond my abilities to complete successfully.

   Thanks very much for your time and consideration,

The problems that I would like to highlight with Spring was the slow

GWT + Spring Roo + Objectify
GWT + slim3 + Objectify / Twig
GWT + Guice + Objectify / Twig
Non GWT + Any of above options
Any other options?

[appengine-java] Re: OneToOne relationship with java.lang.Long ids

2010-10-12 Thread Stevko

Ah, if you want to do this with a relational model rather than a
networked model, you would define your objects such that each is a root
entity (and thereby ids can be type Long ). This is analogous to
holding a foreign key rather than embedding the owned entity.


@Entity
public class Event {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
Long _id;


// store the id of the User rather than the User object itself.
Long _host_id;
...
}


The hardest thing with proofing a model decision like this is scoping
the transactions based on your use cases.
Coordinating multiple separate transactions on separate entities makes
for interesting roll-forward / rollback coding.

if oauth_token:
oauth_token.secret = sess['oauth_token_secret']
oauth_token.oauth_input_params = gdocs.GetOAuthInputParameters()
gdocs.SetOAuthToken(oauth_token)

oauth_verifier = request.GET.get('oauth_verifier', '')
access_token =
gdocs.UpgradeToOAuthAccessToken(oauth_verifier=oauth_verifier)

if access_token and users.get_current_user():
gdocs.token_store.add_token(access_token)
elif access_token:
gdocs.current_token = access_token
gdocs.SetOAuthToken(access_token)

return HttpResponseRedirect('/listdocs')
else:
if users.get_current_user():
req_token = gdocs.FetchOAuthRequestToken(

sess['oauth_token_secret'] = req_token.secret
approval_page_url =

But it works if we i change the client from

gdocs = gdata.docs.service.DocsService(source=SETTINGS['APP_NAME'])

May I know what is the difference? Since i know that DocsService

Re: [google-appengine] Re: Site not working after update

2010-10-12 Thread Andrius A

Thanks for your help guys! Site deployment finally worked! Jamie, is it
working for you as well?

Would be nice to get response from google, since dont know if site
deployment fixed automagically or someone from google did something. Code
bugs should not block the site deployment process.

Hello,

could someone from google have a look at site: bidshapeauction

Site stopped working after update, the same code works fine on other

Site is really slow to load.

On google app engine I see anomaly with Memcache, anyone having issues?

[google-appengine] Why initial_value's type of memcache.incr() atomically change to str?

2010-10-12 Thread 风笑雪

Hi, I found a problem when setting initial_value of memcache.incr()
and memcache.decr().

See this code:

from google.appengine.api import memcache

memcache.delete('a')
memcache.incr('a', 1, initial_value=0)
print type(memcache.get('a'))
print (memcache.get('a'))

Result:
type 'str'
1

I think it should be type 'int' instead of type 'str'. Is it a bug?

[google-appengine] Re: Large datastore queries much slower with Python than Java?

2010-10-12 Thread Tim Hoffman

Hi

I know this is a nit, but with the python version, is there any
particular reason why you are doing

objects = list(q.Get(fetch_size))
nfetched += len(objects)

at line 108 in test_load_query.py

the list() is redundant, the result from Get is for all purposes is a
list or at least exceedingly list like that you wouldn't bother
creating another list from it.

objects = g.Get(fetch_size)
nfetched += len(objects)

It really won't make any difference to the performance.

  Well.. for one.. you are doing a datastore.query() instead of a db.query()
  Most all documentation on working with the datastore indicates to use db
  from google.appengine.ext instead of datastore from google.appengine.api.
  Maybe there is a difference in how they perform in this context?

 The performance of the high-level db api is pretty similar to the
 performance of the low-level datastore API. I used the low-level api
 so that I could keep the code reasonably similar for both Python and
 Java. I'm much less familiar with the Java datastore API and I didn't
 want to use Java layers that might muddy the waters performance-wise.
 Having used the low-level api for Java, I used the closest
 corresponding apis for Python.

 The reason I wrote these simple Python and Java projects was to
 investigate datastore query performance issues I had in real Python
 code (using google.appengine.ext.db), and comparing notes with a
 colleague who was familiar with Java datastore performance.

  Also, are you doing these tests on Appengine or in the Dev_appserver?

 These tests are on the appengine, not the dev server. I use the same
 application name for both Java and Python versions, and different
 versions for both (Java = v1, Python = v2) so that they share the same
 datastore.

Re: [google-appengine] index [X, X, X, Y, Z] built failed and always be resulted in Error state

2010-10-12 Thread Nick Johnson (Google)

Hi Eric,

This is a classic 'exploding' index. With 10 elements in the list, this
index will try to generate 10*9*8*7*6 = 30,240 index entries - far above the
limit. It's not possible to build this index. Consider restructuring your
data, or using merge join queries.

Re: [google-appengine] index [X, X, X, Y, Z] built failed and always be resulted in Error state

2010-10-12 Thread Jeff Schwartz

Hi Nick,

From the docs at
http://code.google.com/appengine/docs/java/datastore/queriesandindexes.html#Big_Entities_and_Exploding_Indexes
:

You could call an index that refers to multiple properties with multiple
values an exploding index, because it can get very large with just a few
values.

I believe the key words in the above are multiple properties with multiple
values however I cannot see anywhere where there is a compound index using
multiple properties that include the list property which according to the
above is what would/could create an exploding index. I should preface this
by saying that I am not a python developer so if there is something in the
yaml file that does create this situation I apologize but would you mind
pointing out what in the yaml file is?

Thanks in advance.

Re: [google-appengine] Re: Multiple Domains for one app, even if you don't own the domain, or if other domain is already registered with Google Apps

Hi James,

I edited my GoDaddy DNS A and CNAME records and was able to point the
naked domain at my app engine app. It's possible to do even though
different resources on the Internet claim that it's impossible. I
suspect that Google means that it's impossible to do from Google Apps
or the App Engine Dashboard, but that doesn't include advanced DNS
configuration.

* I configured an A record to point *.domain.com to my app engine app
IP Address

*.domain.com will map all subdomains to the same IP, not the 'naked'
domain.

Further, ghs.google.com resolves to a number of IPs; these IPs change over
time and depending on the location of the requester. Simply choosing one
from the list will not work reliably.

Finally, App Engine will not be able to route your incoming requests
correctly unless it's aware of your mapping, which it's not possible to do
for a naked domain.

-Nick Johnson

* I configured a CNAME for www.domain.com to point to ghs.google.com

I suspect that one of those two changes may have something to do with
my success. Although honestly this isn't something that I do on a
regular basis. Hope this helps! If it does, awesome!

You can't point the naked domain at an App Engine app at all.

However, App Engine doesn't control your DNS settings. You set CNAMEs
for the subdomains you want handled by App Engine or other Google Apps
services to ghs.google.com, and setup CNAME or A records for the other
addresses in your domain to point to wherever you want them to go.

application to their Google Apps account and point any URL for that
domain to your app engine application. They would do this by:

1. Logging into their Google Apps account
2. Click on Add more services
3. Enter app id on the Google App Engine section under Other

I am not 100% sure the above is true, but it seems to have worked for

Re: [google-appengine] index [X, X, X, Y, Z] built failed and always be resulted in Error state

So a list property with 5000 entries in it that is not part of any compound

would if it were part of a compound index, correct? Nor would querying on a

The reason I am asking all these questions is because I've implemented a

[google-appengine] Serious problem caused process to exit... but where are my logs?

2010-10-12 Thread Starman

Hi there,

My app is doing great locally. It deploys fine.

Now I get this error in my logs everytime I try to execute a couple of
updates to the datastore in the same transaction. In fact, I know part
of my code executes OK since one of the updates makes it to the
datastore but the other does not. And it's not busting the 30 seconds
limit as this transaction takes less than a second locally. Each
entity is part of a different entity group... but I had disabled
transactions when I was using jpa.  I have recently switch from java/
jpa to Objectify. I am also not using transactions and should be able
to update different entity groups within the same transaction.

My question really is, how come you don't get any log output when the
request causes the process to exit? Makes it pretty hard to find the
issue.

I have tried updating different entities, calling the task directly
instead of having the task queue api do it, removed security, changed
the http error codes returned, catching errors and logging them
somehow... and a bunch of other things.

What would really help would be running with full debug logging on and
getting my log output.

Thanks for an otherwise incredible platform,

Remy

[google-appengine] Re: TransientError on adding task queue, yet the status page says no error.

2010-10-12 Thread John Gardner

I've seen this periodically.

The pattern that seems to be percolating around the list is to always
wrap a task insertion (if important) in an try/except, and resubmit
the job on failure.

Myself, I try to insert once in the except block, and then throw up my
hands forever.  That appears to be work so far.

From the slide Building scalable, complex apps on App Engine by Brett
Slatkin

http://dl.google.com/io/2009/pres/W_0415_Building_Scalable_Complex_App_Engines.pdf

we learn techniques for building scalable services by using list and self
merge-join. self merge-join is very useful to me as it does not require
building additional custom indexes (the hard limit of 200 custom indexes
is
always a headache for me with my application, and always have to use many
different techniques to reduce the custom indexes usage)

however, recently i hit a problem
NeedIndexError: The built-in indices are not efficient enough for this
query
and your data. Please add a composite index for this query.

My model is very simple, just like this
class Searchable(db.Model):
phrases = db.StringListProperty()

the query is
query = searchable.all().filter('phrases =', word1).filter('phrases =',
word2).fetch(1000)

It works fine before. But now fail with some cases.
I re-read slides, and find that about merge-join performance
Scales with number of filters and size of result set Best for queries
with
fewer results (less than 100)

i guess very likely, now when my application scales with more data (let
say
Searchable now stores 1 million records), when doing the query and if the
result set is large (how large is large? 100?), i would then hit this
'built-in indices are not efficient enough' problem. the query works fine
if
the returned result set is much smaller

this is my guessing. so my questions are
1. is my guess correct / making sense? what other cases would
cause 'built-in indices are not efficient enough' problem? are there any
others share similar experiences?
2. is there any hard number, or formula, we can use to estimate by how
large
the result set is, would hit the 'built-in indices are not efficient
enough'
problem? other than size of result set, would there be other factor
matter?
(number of self merge-join, number of properties, number of indexed
properties etc.)
3. the most important question, any solution / workaround for that ?
(other
than building extra custom indexes which is not quite feasible for me as
i'm
already having 200 indexes)

appreciate for any comments / suggestions.

Re: [google-appengine] index [X, X, X, Y, Z] built failed and always be resulted in Error state

2010-10-12 Thread Robert Kluin

Nick is saying that the StringListProperty has values like: A, B, C.
If you also have another property, say an IntegerProperty with value
7, and you create a compound index that contains the IntegerProperty
and the StringListProperty you will be OK because the index will look
like:
   7-A
   7-B
   7-C

However, if the index contains the IntegerProperty and the
StringListProperty twice the index looks something like:
   7-A-A
   7-A-B
   7-A-C
   7-B-B
   7-B-C
   7-C-C

The issue is NOT from one multiple valued (ie ListProperty) being in a
compound index once, but rather from one or more multiple valued
properties appearing more than one time in the same compound index.

151) and _decode_value (line 205).  The value gets converted to a str
when set, but should be decoded to an int when you call get.

 Hi, I found a problem when setting initial_value of memcache.incr()
 and memcache.decr().

 See this code:
 
 from google.appengine.api import memcache

 memcache.delete('a')
 memcache.incr('a', 1, initial_value=0)
 print type(memcache.get('a'))
 print (memcache.get('a'))
 
 Result:
 type 'str'
 1
 
 I think it should be type 'int' instead of type 'str'. Is it a bug?

[google-appengine] Google Apps / Domain verification

2010-10-12 Thread Tim Jones

I'm trying to setup a new domain name for my GAE app by adding a domain alias 
to my Google Apps account. I've verified the new domain through a CNAME, but 
now Google Apps is asking me to setup email for the domain by changing MX 
records.

I don't want to setup email for this domain, I just want to host my GAE app on 
it. Any ideas on how I can add this domain to Google Apps without dealing with 
MX records?

When I setup my GA account's primary domain, the CNAME was sufficient. I'm not 
sure why adding a Domain Alias seems to require this extra step.

Ben, thanks for your code! I'm trying to understand all this stuff

Robert, any success with your library? May be you've already done
all stuff we are trying to implement...

p.s. where is Brett S.:) would like to hear his comments on this

 Thanks for your insights. I would love feedback on this implementation
 (Brett S. suggested we send in our code for this)http://pastebin.com/3pUhFdk8

 This implementation is for just one materialized view row at a time
 (e.g. a simple counter, no presence markers). Hopefully putting an ETA
 on the transactional task will relieve the write pressure, since
 usually it should be an old update with an out-of-date sequence number
 and be discarded (the update having already been completed in batch by
 the fork-join-queue).

 I'd love to generalize this to do more than one materialized view row
 but thought I'd get feedback first.

 Thanks,
 Ben

   I have a question about Brett Slatkin's talk at I/O 2010 on data

   to minute 51:30 of his talk
  http://code.google.com/events/io/2010/sessions/high-throughput-data-p...

   I am wondering what is supposed to happen in the transactional task
   (bullet point 2c). Would these updates to the materialized view cause
   you to write too frequently to the entity group containing the
   materialized view?

  I think there are really two different approaches you can use to
  insert your work models.
  1)  The work models get added to the original entity's group.  So,
  inside of the original transaction you do not write to the entity
  group containing the materialized view -- so no contention on it.
  Commit the transaction and proceed to step 3.
  2)  You kick off a transactional task to insert the work model, or
  fan-out more tasks to create work models  :).   Then you proceed to
  step 3.

  You can use method 1 if you have only a few aggregates.  If you have
  more aggregates use the second method.  I have a library I am almost
  ready to open source that makes method 2 really easy, so you can have
  lots of aggregates.  I'll post to this group when I release it.

   And a related question, what happens if there is a failure just after
   the transaction in bullet #2, but right before the named task gets
   inserted in bullet #3. In my current implementation I just left out
   the transactional task (bullet point 2c) but I think that causes me to
   lose the eventual consistency.

  Failure between steps 2 and 3 just means _that_ particular update will
  not try to kick-off, ie insert, the fan-in (aggregation) task.  But it
  might have already been inserted by the previous update, or the next
  update.  However, if nothing else kicks of the fan-in task you will
  need some periodic cleanup method to catch the update and kick of
  the fan-in task.  Depending on exactly how you implemented step 2 you
  may not need a transactional task.

  Robert

   Thanks!

You do not need to change MX records if you do not want Gmail for
Apps.

The only change required is CNAME-ing your record to ghs.google.com.

Re: [google-appengine] Google Apps / Domain verification

2010-10-12 Thread Tim Jones

Then I'm not sure what I need to do to setup this domain name.

When I try to add my new domain to my GAE app, it says Sorry, you've reached a 
login page for a domain that isn't using Google Apps.

And when I go to my Google Apps Domain Settings page, the status of my new 
domain just says MX records setup validation in progress... 

Any suggestions on what my next step should be?

[google-appengine] Re: TransientError on adding task queue, yet the status page says no error.

2010-10-12 Thread Jamie H

I am curious if by using deferred instead of tasks you will still have
to worry about TransientErrors ?  Since the deferred library handles
inserting the task... I don't see anywhere in the docs of deferred
saying you must worry about TransientError...

On the same note I am curious if anybody knows if tasks are added or
not when a transient error is thrown.  I would assume they aren't but
I have seen some references in the group that they are in fact added
despite a TransientError.. any word on this?  I rely heavily on tasks
so it is very important I can be assured that when I add one it will
be added...

On Oct 12, 11:54 am, John Gardner hux...@gmail.com wrote:
 I've seen this periodically.

 The pattern that seems to be percolating around the list is to always
 wrap a task insertion (if important) in an try/except, and resubmit
 the job on failure.

 Myself, I try to insert once in the except block, and then throw up my
 hands forever.  That appears to be work so far.

[google-appengine] CPU burn rate 10 times higher today on this error: The API call datastore_v3.Get() was explicitly cancelled.

2010-10-12 Thread Alan Xing

Hi GAE Team,

Our app 'snsanalytics' is experiencing the following error frequently:
CancelledError: The API call datastore_v3.Get() was explicitly cancelled.

Whenever this error happens, a deferred job eats up 50,000+ cpu_ms. This
causes our app is burning CPU at 10+ times higher than normal rate every
hour. Could any one help investigate ASAP?

Alan

The problem doesn't happen all the time though. To help you better diagnose,
we have kept the version 2 of the app 'snsanalytics' unchanged. You can see
the problem clearly from the most recent log of version 2.
