This has been my experience as well.  Additional indexes cost a lot,
but additional unindexed properties seem to be almost "free" in the
datastore.

I would ask of anyone asking for select at a property level:  Have you
run any performance tests of your application with big vs small
entities?  Are you sure it matters?

[google-appengine] Intercepting all HTTP calls on webapp/django

[dhruvbird]

Hello,
  I was wondering how to best intercept all HTTP calls to my appengine
app. From what I read here (http://blog.notdot.net/2010/01/Webapps-on-
App-Engine-part-1-Routing), it seems as if defining my own router and
then delegating the real work to the webapp/django router seems like a
fair thing to do.
  I want the solution to be framweork independent. Please let me know
if anyone has an easier/cleaner solution.

Regards,
-Dhruv.

Re: [google-appengine] Any plans to implement something like: "Select myProp From myModel"?

[Robert Kluin]

Hey Eli,
  Just a quick comment.  On some of our models we are now doing
something similar to what you suggest.  On models with a lot of
unindexed fields we add a text (or blob) property, then we serialize a
dict of values and store in that field. We do this especially when the
fields are not always needed.  In testing, I am pleased with the
results so far.

  Also, if we know that certain groups of fields will usually be
needed together, then we put them in a group together. Then we save
the cost of deserializing everything unless we need to.  This seems to
be working well.

  Although I have not personally tested with _really_ large entities,
I see very little difference in performance based on the size of the
entity.  We have some models with 20 or 30 string and float fields
that seem to perform similar to models with 5 or 6 string fields.
There have been a number of threads discussing this in the past.  I
think a post had some benchmarks in December or January.

Re: [google-appengine] Any plans to implement something like: "Select myProp From myModel"?

[Eli Jones]

Oh.. and, I guess, the quick workaround for something like this would be to
have your Model be defined like so:

class myModel(db.Model):
myBigProp = db.BlobProperty()

and then you would have myBigProp be a compressed Model like so:

class myBigPropClass(db.Model):
prop1 = db.prop()
prop2 = db.prop()
...
prop100 = db.prop()

so.. when you constructed a myModel entity you did something like this
(naturally, this is pseudo code):

myProps = myBigPropClass(prop1 = blah, ..., prop100 = blah100)
compress = zlib.compress(db.model_to_protobuf(myProps).Encode(),9)
model = myModel(myBigProp = compress)
model.put()

I'm not sure if I can directly compress a protobuf... but that would be the
general idea.. mainly, the cost you spend on compression, decompression
isn't near as much as the cost you take on puts on the non-compressed data
or on the transfer during the get possibly..

Naturally, I would need to test this performance.. I know the put() cost of
the compressed data is much better in total.. I just haven't checked what
sort of hit you take on gets.

But, if you have really big entities.. you benefit greatly from the
compression. (Since the datastore is somewhere else.. and not right there
with your app instance)

Anyway, in the IO talk linked to above, Mr. Slatkin mentions that they are
looking into implementing a way to get specific properties with a get() ..
so.. it was on the radar.

[google-appengine] @Google: Can't delete two old versions of my app

[esilver]

Hi - This is the same issue as:

http://groups.google.com/group/google-appengine/browse_thread/thread/b22977b26a769028/49817ecfd8a80975?lnk=gst&q=server+error+occured+delete#49817ecfd8a80975


For my app, version v1-03 and v1-10 of husbandmaterialapp are un-
deletable - a server error occurs when I attempt to delete either one
of them. The former is more than a month old.

Is there any fix for this or do they have to stay around as zombie
versions?

Thanks,
-Eric

[google-appengine] Re: Any plans to implement something like: "Select myProp From myModel"?

[Tim Hoffman]

Honestly can't see it ever happening.

You have to realise you aren't using a traditional database.

So with the current api based on db.Model you are dealing with
entities. End gql is predicated on that model.
zope's zodb works in a similiar fashion.

You would have to come up with a different hi-level api or use the
lowlevel api yourself to achieve this sort of thing.

Re: [google-appengine] Any plans to implement something like: "Select myProp From myModel"?

[Eli Jones]

First off, that is a good talk.  And I like it very much.  But, it is still
speaking of the workaround one can do to create a multi-part Model to query
some part by __key__ and then grab the specific parent that contains the
only props you want.  You are still limited to partitioning your Models out
into these specific parent, child relationships.. and then keeping track of
those relationships and issuing queries based on said relationships.

The particular case I'm talking about is one where you have a Model with 100
properties that are all unindexed... so.. you only have an index on the
key_name.

You can define multiple Models that are related.. but you will still have to
deal with an index on the key_name for each Model (I am assuming).

I want to know if it would ever be possible to have a single Model.. with a
single key_name with one index.. and then be able to selectively pull
particular properties for that Model..

so.. if I want to update any three random properties, I issue a query that
requests those properties.. updates them.. and puts() the entity back to the
datastore.. only having to update those specific properties.  In that
situation, you wouldn't have the overhead of getting and putting properties
that weren't going to be touched.

Primarily, I'm wondering if there will ever be a way to avoid the overhead
of pulling all properties for a Model when I only want to update a few of
them.  (The bandwidth used significantly impacts latency on the get() and
the put() if the entities are fairly large)

Re: [google-appengine] Any plans to implement something like: "Select myProp From myModel"?

[Raymond Ling]

I recommend this
video
(Youtube
Link:
http://www.youtube.com/watch?v=AgaL6NGpkB8&playnext_from=TL&videos=geh1T1kPh70
).

The simple way to avoid loading big property one time is to design the
property as 
owned-relationship
.

To keep the consistency between the object in your memory (maybe use
memcache) and entity in datastore, it's better to load all properties one
time (except for big properties that may cause performance issue).

[google-appengine] Re: Looking for a library to sanitize input, transcode to UTF-8

[Tim Hoffman]

Hi

Have a look at webob 
http://pythonpaste.org/webob/reference.html#unicode-variables
and note if your running as an API server your
api consumers should probably be specifying the encoding in the their
headers.

Also its difficult to blindly encode something to UTF-8 as what they
send may not in fact be possible to encode
without stripping or translating some values to something else
entirely (for instance if some one send you UCS4)
which is something you will have to deal with on a case by case basis
for different encodings.

You could then document which encoding schemes you directly support in
your api, and then get the consumers to
set the content type charsets correctly.

Just my 2c worth

[google-appengine] Re: Any guarantees on time sync among servers?

[kazunori_279]

Hi Ikai,

Oops, I pasted a wrong link. Here's my code:

http://code.google.com/p/sth-samples/source/browse/trunk/sth-samples/src/jp/co/sth/samples/service/CounterService.java

By "Log" I do not mean the log messages, but actual entities which
works as journals of the counter updates (or whatever you write on
memcache). Instead of updating existing entities (which can be a
bottleneck), it would be scalable to add new entities to gain the
durability.

Thanks,

[google-appengine] Any plans to implement something like: "Select myProp From myModel"?

[Eli Jones]

Are there any plans to (or is this even feasible) to implement the ability
to pull only specific properties for an entity from a model?

Say I have a Model like so:

class myModel(db.Model):
myProp = db.StringProperty()
myProp2 = db.ListProperty()


And.. I want to do a myModel.get_by_key_name(mykey).. but I only want the
StringProperty... will there every by a way to specify that I just want to
have the myProp value returned?

So, say myModel had 20 properties.. but for any given query, you only wanted
2 or 3 of those properties.. will there ever be  away to restrict the
returned value to contain only those specific properties?

Then.. it would be nice to get only a few properties for an entity.. and
then update those entities and the .put() would only need to send the
updated values over the wire..

Or, is this a fundamental limitation of the datastore.. or is this already
happening behind the scenes?

Thanks for information.

That's what the documentation seems to say, although I haven't tested it:

and

[google-appengine] Re: Looking for a library to sanitize input, transcode to UTF-8

[Brian]

The problem with that is that our system is an API server, so we can't
assume that submitters are actually sending UTF. They usually are, but
sometimes not.

[google-appengine] Appstats caused java OutOfMemoryError - heap

[Jake]

I have a rather large and intense sorting process that runs
periodically.  When I enabled Appstats, this process started to fail
with the following trace.

When I disabled Appstats, it went back to normal.

I really liked Appstats, too. sigh.

Re: [google-appengine] gdata client libraries

[Jason (Google)]

I'm prepping a Google Data + App Engine article right now which uses the
Java runtime. This is what I have regarding dependencies, specifically for
the Documents List service:

---
To use the Google Data client library (
http://code.google.com/p/gdata-java-client/) in your App Engine application,
you must first copy the JARs listed below from the lib directory of the
gdata-java-client package to your app's war/WEB-INF/lib directory:

gdata-client-1.0.jar
gdata-client-meta-1.0.jar
gdata-core-1.0.jar
gdata-docs-3.0.jar
gdata-docs-meta-3.0.jar
gdata-media-1.0.jar
google-collect-1.0-rc1.jar (from gdata/java/deps)

Once all of these JARs are copied into war/WEB-INF/lib, they must be added
to your app's build path. If you are building your application in Eclipse,
just follow the instructions at
http://www.wikihow.com/Add-JARs-to-Project-Build-Paths-in-Eclipse-%28Java%29.
Otherwise, if you are using the sample ant build.xml file at
http://code.google.com/appengine/docs/java/tools/ant.html#The_Complete_Build_File,
all JARs in war/WEB-INF/lib should be added to your app's build path
automatically.
---

If you are not using the Google Documents List API, you will have to replace
gdata-docs-3.0.jar and gdata-docs-meta-3.0.jar with the JARs for the service
you're trying to use. Also, be sure you're following this FAQ:

http://code.google.com/appengine/kb/java.html#googledata

I hope this helps.
- Jason

Re: [google-appengine] Re: Huzzah! My App's Finally Live.

[Patrick Twohig]

Ikai,

THe Android version is in the works, but the last Android app we put out
bombed miserably so we went to iPhone.  Though since it's Java, I can
probably copy a bunch of the stuff over to the Android client and turn it
around much faster than the iPhone version.  You also may be interested to
note is that we advertised the application at PAXE in Boston this past
weekend.  People definitely responded to the ad and our usage ramped up
quite high and AppEngine kept up with few issues.  On that note, how do I
feature it in the App gallery?

Derek:

It's all Polling over HTTP.   The original design used push notifications
combined with polling, but that ended up not happening and we just went with
polling.  It's not ideal, and I'd like to take the comet approach at some
point to make it a bit more responsive.

Pat.

[google-appengine] Re: html5 cache ... is it working?

[Nash-t]

Update:
GAE production and dev both support this ok.
This not really a GAE issue. Sorry for posting here.
It looks like you cannot put spaces before the CACHE MANIFEST line.
With spaces there, the database is created but no files are stored.

This cache.manifest file creates a database and stores the file:
CACHE MANIFEST
# version 10
http://extjs.cachefly.net/builds/ext-cdn-8.js
# /static/ext-all.js
# static/ext-all.js
#ext-all.js

[google-appengine] Re: Performance Profiling Url

[Thomas Johansson]

There's a number of bugs with this, unless it has been fixed in 1.3.2
- Specifically:

- The URL logged with each request is hardcoded to /stats.
- Some URL's in the appstats UI link to /stats, hardcoded.
- Some redirects in appstats are again, hardcoded.

I tried overriding the setting in appengine_config.py, but it still
did it.

Re: [google-appengine] Allow/Deny IP Address

[Ikai L (Google)]

That's because it's not a guaranteed blacklist. You're supposed to use the
DoS API to prevent a massive attack, not as an ACL. If you need to
whitelist, you'll have to write the whitelist programmatically as either a
WSGIMiddleware (Python) or ServletFilter (Java).

[google-appengine] Very high latency in some cases to receive the HTTP method calls

[mandar khadilk]

Hi,
I am using Java GAE implementation.
I have been experiencing very high latency times in some cases before
an HTTP method gets called in my Servlet. I understand that it may be
the time it takes to make the server context up from a cold state for
my apps. But 5-8 second is very high time.

Any idea how to speedup this time?

Re: [google-appengine] How to pay for more than 1,300,000 requests per day?

[Shawn Hartsock]

I did some math on this recently for my application but my
application's numbers won't fit your application. Each application is
going to have a different performance profile. You need to profile
your application and determine what it will use in resources. My
application is very CPU intensive so I've used my CPU quota well
before ever reaching my request quota.

As I understand it you'll face a recurring charge for data persisted
above the quota.

http://code.google.com/appengine/docs/quotas.html
http://code.google.com/appengine/docs/quotas.html#Datastore

I used the numbers in that link, along with a few days worth of
profiling data from my application, coupled with an AdSense revenue
projection to determine what performance criteria the application
would have to fulfill to be profitable should it become popular and
need to scale beyond free. If you are seriously thinking you'll go
beyond 1.3 million requests a day I suggest you do some math along the
same lines.

[google-appengine] When using frames, authentication does not happen....

[sri]

Hi,

I am using frames in my html. On left hand, I have signout (I use
google's signout servlet). On the right side is the target. so for
instance:

I have:

left.html

X

Signout


index.html contains:



Now... after uploading the files to appengine site, I navigage through
the secure/addX.html for the first time. It asks me to authenticate.
Then, I signout (which works fine)... but then, when I click on
addX.html, it does not ask me to authenticate again... just executes
the page...

Am I missing something ?


Thanks in advance for the response.

[google-appengine] Moving from Blogger to AppEngine

[David Burns]

Hi,

This is probably an extremely stupid question but just want to know
what I am expecting. It is because its moving between Google services
that I am just not 100% sure what to expect where if it were between
different providers I think I know what I would expect

I have a subdomain that i want to move to move from blogger to
appengine.

The CNAME is currenly pointed at ghs.google.com. for blogger and the
CNAME for app engine is the same so is it going to be a simple case of
deleting the custom domain on advanced settings of publishing in "Your
Domain" and saving it and then creating a new URL on Google Apps for
the new AppEngine app?

The .htaccess of Apache can provide two way ip restriction.

Re: [google-appengine] Re: Any guarantees on time sync among servers?

[Ikai L (Google)]

That link goes to a groups post.

I wouldn't use logging for this. Right now we are saving logs for what looks
like 90 days, but this may change such that logging is only until you run
out of space. Also - you can't programmatically filter on values in logs at
the application level easily.

Re: [google-appengine] getting ValueError('insecure string pickle',) error when attempting to start dev environment with a preexisting datastore

[Nick Johnson (Google)]

Hi,

Have you been using the sqlite stub? If so, you need to call
--clear_datastore to clear it.

The error you're getting occurs when the standard datastore stub can't read
the datastore file (for example, because it's corrupted, or because it's
actually an sqlite database). Clearing it will fix this.

Re: [google-appengine] How to pay for more than 1,300,000 requests per day?

Hi Mark,

The requests-per-day quota is one of our 'non billed quotas'. Enabling
billing automatically increases it (currently, to 43,200,000), regardless of
what amount of budget you allocate to each billed resource.

If you manage to exceed 43 million requests per day, you can talk to us and
we'll extend it. If you reach that without needing to pay for any extra CPU
quota, I'll happily buy you a beer and write a case study about your app. ;)

1.3million hits/day is a lot.  Very very few sites even approach a couple 
hundred k.  Data storage profiles are similar.  This comes from working at 
a relatively large dynamic (php mostly) app hosting company for 6+ years. 
1.3million is an average of 15 hits/second all day long.

They don't bill per hit, they bill for data transferred to/from users, and 
other categories, as defined:




and described at:

Marks resources as (billable) or fixed and explains each.

Re: [google-appengine] Performance Profiling Url

I assume this is the Appstats library? If so, then from the blog post about

"The url here - ‘/stats’ - can be anything you like, as long as it ends with
‘/stats’, and is the URL that you can access the Appstats admin console
over."

[google-appengine] Performance Profiling Url

[vivpuri]

AppEngine team, thanks for adding the Performance Profiling app. But
the choice of url: /stats is not the best choice this late in the
game. I dont think /stats was a reserved url handler anyway. And as
you can guess, after appengine being live for this long amount of
time, there can be apps using this url handler. At least this is the
case with my app. In simpler words, can we have the url handler
changed to /_stats for the Performance Profiling?

[google-appengine] How to pay for more than 1,300,000 requests per day?

[Mark]

Hi,

I'm trying to plan out how much an app could potentially cost to run.
I'm looking at the quotas here:

  http://code.google.com/appengine/docs/quotas.html

it says we get a free limit of 1,300,000 requests per day, and 1gb of
free storage.

I think my app is going to run over the 1gb storage limit, and the
1,300,000 calls per day limit, but possibly none of the other quotas.
How does billing work in this scenario? Can we pay for more than
1,300,000 requests per day? I'm not seeing where this would be charged
in the billing screencast here:

  http://code.google.com/appengine/docs/billing.html

Also, in general, are there any rough comparisons that have been done
that show how much more cost-effective it is to use app engine at
different usage rates vs other hosting plans? Just curious,

Thanks

Re: [google-appengine] Re: data center location

[Jody Belka]

I just checked out the EU data protection situation for this, and seems to
be okay

Although the US isn't on the list of countries with "adequate protection",
data sent to the US under the "Safe Harbor" scheme /is/ considered
adequately protected, and Google is registered with said scheme.

So though it would definitely be nice to be able to choose an EU
data-centre, the situation is at least not as bad as it might be.

In that case, it's probable your handler is not being called at all. Have
you checked the logs to see if it is, and what status code it's returning?
Is this on the dev server, or in production?

 This code creates a new Greeting, and sets the content, but never saves
 it to the datastore. You need to call .put() on 'greeting'.

Sorry about not explaining well.

The entity does not appear in the Datastore and I am not seeing the log

What do you mean by "does not work"? Does the log message get written? Does
the entity appear in the datastore entity viewer? How are you determining
that it does not work?

Re: [google-appengine] Re: Beginner Help - Python Incoming Mail

[Jon Byrne]

Thanks Nick

So should this work?


import logging, email
from google.appengine.ext import webapp
from google.appengine.ext.webapp.mail_handlers import InboundMailHandler
from google.appengine.ext.webapp.util import run_wsgi_app
from google.appengine.ext import db

class Greeting(db.Model):
content = db.StringProperty(multiline=False)

class LogSenderHandler(InboundMailHandler):
def receive(self, mail_message):
logging.info("Received a message from: " + mail_message.sender)
greeting = Greeting()
greeting.content = mail_message.subject
greeting.put()


I have tried this and this does not work, I have also tried using
greeting.content = "some" just to make sure its not a problem with
mail_message.subject but still no joy.

If I greeting.content in a seperate class it does write to the datastore but
I am unable to use the mail_message.sender value.

Sorry for being a bit simple

This code creates a new Greeting, and sets the content, but never saves it
to the datastore. You need to call .put() on 'greeting'.

...while this code creates a new, empty greeting, and saves it to the
datastore, which probably doesn't do what you want it to.

Re: [google-appengine] Re: Beginner Help - Python Incoming Mail

[Jon Byrne]

Thanks for that I have sorted that side of things but am struggling to get
the email into the datastore.

I am using this code


import logging, email

from google.appengine.ext import webapp

from google.appengine.ext.webapp.mail_handlers import InboundMailHandler

from google.appengine.ext.webapp.util import run_wsgi_app

from google.appengine.ext import db


class Greeting(db.Model):

content = db.StringProperty(multiline=False)


class LogSenderHandler(InboundMailHandler):

def receive(self, mail_message):

logging.info("Received a message from: " + mail_message.sender)

greeting = Greeting()

greeting.content = mail_message.subject


class Guestbook(webapp.RequestHandler):

   def importsender(self):

greeting = Greeting()

greeting.put()


But do not get anything in the datastore or an error. Where am I going
wrong?

Re: [google-appengine] "File referenced by handler not found"

[djidjadji]

Just use this
-
- url: /mypicpickup_(.+?)\.jpg
 script: mypicpickup.py
-
script should only point to the python file. NO static file syntax.
