Re: [appengine-java] Re: [google-appengine] Re: CMS for GAE

[Anton Danilchenko]

Thanks for a question!

Yes, blog application allow you to create sections (categories) and create 
pages (articles) into selected section. This is similar with CMS 
functionality. But we have not support change templates in web-based editor. 
You can change design of your web site one time, and this is affected each 
page.

Currently we have moved our applications to new version 2.0. But this apps 
not tested yet. We have two blogging systems - blog and blogs applications. 
Blog app - allow only for admin create and edit articles and sections. Blogs 
app - allow each user create personal blog and work with this blog. We need 
to complete both this applications to add flexibility to use for a different 
tasks.

Best regards, Anton.

[google-appengine] Need help understanding Appengine billing

[Kwame]

I've been using Appengine for a while, and I haven't yet exhausted my
free quota. I'm running a business and I would need to set a budget
for my server costs. I'm not able to understand how the billing units
like CPU Time, Outgoing Bandwidth, Incoming Bandwidth & Total Stored
data apply in real world usage of a typical busy website. Can anyone
give me some sample charges for a typical website and approximately
how much of these resources can be expected to be consumed, so I can
compare with my site to get an approximate estimate.

Thanks.

[google-appengine] Bad Performance for Dedupe of 2 million records using mapreduce on Appengine

[charming30]

I have about 2 million records which have about 4 string fields each
which needs to be checked for duplicates. To be more specific I have
name, phone, address and fathername as fields and I must check for
dedupe using all these fields with rest of data. The resulting unique
records need to be noted into db.

I have been able to implement mapreduce, iterarate of all records.
Task rate is set to 100/s and bucket-size to 100. Billing enabled.

Currently, everything is working, but performance is very very slow. I
have been able to complete only 1000 records dedupe processing among a
test dataset of 10,000 records in 6 hours.

The current design in java is:

In every map iteration, I compare the current record with the previous
record
- Previous record is a single record in db which acts like a global
variable which I overwrite with another previous record in each map
iteration
- Comparison is done using an algorithm and result is written as a new
entity to db
- At the end of one Mapreduce job, i programatically create another
job
- The previous record variable helps the job to compare with next
candidate record with rest of the data
- I am ready to increase any amount of GAE resources to achieve this
in shortest time.

My Questions are:

- Will the accuracy of dedupe (checking for duplicates) affect due to
parallel jobs/tasks?
- How can this design be improved?
- Will this scale to 20 million records
- Whats the fastest way to read/write variables (not just counters)
during map iteration which can be used across one mapreduce job.
- Freelancers most welcome to assist in this.

Thanks for your help.

[google-appengine] GAE Remote API or GWT’s RequestFactory?

[Rafael Dipold]

Hi,

I want to build an software financial control that's uses infraestrutura of 
GAE to data and logic tier.
In the presentation tier I would like to use the JavaFX technology.
My doubt is with relation the comunication between the presentation and 
logic tier.
I read and tested two technology in a single CRUD app and both work's fine:


   - Remote API
   - GWT’s RequestFactory


The Remote API is more simple but I'm not sure if I understand the best use 
for this toolset. I read in Nick Johnson blog's that is intended purely for 
administrative access, but it work's fine in a single CRUD test that I 
created.
What technology you advises to build data-oriented (CRUD) software like I 
described??

Second question is with the fact that's in my country there are a federal 
law that forces the offline access of any software that's issue receipt for 
sale to consumers. 

There are anyway to do with that there are replication/synchronization 
between a local db like mysql and the datastore in GAE infrastruture?
I read about AppRocket  but I'm not 
sure if this delivers what it promises. Anybody has a suggestion about this?

I'm open to new ideas and appreciate any sugestion.

Kind regards,

Rafael Dipold

[google-appengine] Re: How to restrict access to non-default versions?

[Jose Montes de Oca]

Hi,

just need to add a restriction to the app configuration file to only access 
by the admin.

If you are working with python you would need to modify app.yaml and add 
login: admin to the urls in the handlers section. more info:
http://code.google.com/appengine/docs/python/config/appconfig.html#Requiring_Login_or_Administrator_Status

For java: you would need to add security constrains to your web.xml. more 
info:
http://code.google.com/appengine/docs/java/config/webxml.html#Security_and_Authentication

Hope this helps!

Re: [google-appengine] Adapting an existing webapp to GAE: accessing datastore

[Jeff Schnitzer]

In Eclipse, go to Project Properties -> Google -> App Engine and check the
"Use Google App Engine" box.  That should be enough to get the User Library
added and the libraries set up in WEB-INF/lib, although you might need to
close/reopen the project (and use the auto-correct feature to "synchronize
WEB-INF/lib").

If you want an example Objectify project, look here:

https://github.com/stickfigure/motomapia

Just make sure you have all files in the right place, and you should be
fine.

Re: [google-appengine] Problem using Google Apps Viewer to view a blob

[Joshua Smith]

Excellent question. No, I hadn't.

I just added this:

self.response.headers['Content-Type'] = 
str(mimetypes.guess_type(document.title)[0]) or 'application/octet-stream'

and the headers now say:

HTTP/1.1 200 OK
Cache-Control: no-cache
Expires: Fri, 01 Jan 1990 00:00:00 GMT
Content-Type: 
application/vnd.openxmlformats-officedocument.wordprocessingml.document

But there is no change.  .doc files still work, and .docx files do not.

Any other ideas?

[google-appengine] How to restrict access to non-default versions?

[Craig]

Is there a simple way to restrict access to non-default versions?  I'd like 
for administrators to have access to them, but nobody else.  I'm sure it's 
not too bad to code up something to handle this, but it seems like something 
the platform would provide (although I couldn't find any such feature).

[google-appengine] Re: File downloading to GAE Servers

[Simon Knott]

Hi,

You can use the URL Fetch interface 
(http://code.google.com/appengine/docs/python/urlfetch/overview.html) to 
retrieve the file, and then store it in the datastore or Blobstore as Philip 
has suggested.  If the file is less than 1MB, then you can use the datastore 
and not worry about the Blobstore.

Please note that if you use the Blobstore, you have to have billing enabled 
although you won't pay anything unless you go over the 1GB storage limit.

Cheers,
Simon

Your GAE app is hosted on a read-only filesystem. You have to store
that data in blobstore or datastore.

Re: [google-appengine] Mailing alerts with appengine

[MiuMeet Support]

One thing you should consider is if you want to use appengine as an email
infrastructure.
We run a social network on appengine with 1M+ users and we love it to run
everything on it,
except email. EMail deliverability on appengine is not really great. You
can't do DKIM signing,
you can't send from a dedicated IP address and so on.
We send about 250k emails out per day, but for this we host our own
mailserver with an
http interface that we call via urlfetch. Deliverability is much higher...
but of course it's
an additional point of failure. This morning greengeeks (our hosting
provider) turned off the
server without notice "due to extensive use". So make sure you choose a
dedicated server
provider that doesnt just turn off your machines when they send a lot of
emails. We are now
switching to hetzner.de. A friend of mine runs mailservers there with
millions of emails per day
and claims he never had problems, as long as the emails are legitimate.

Just my 20 cents.

[google-appengine] Adapting an existing webapp to GAE: accessing datastore

[Florent Georges]

  Hi,

  I have an existing Java EE web application.  As it uses only
the Java EE subset accepted on GAE, I successfully deployed it by
exploding the WAR to a tmp dir, adding the appengine-web.xml
descriptor to WEB-INF/, and calling the SDK update command from
the command line.

  So far so good.

  But now I'd like to use the datastore (through JDO, JPA or even
better, through Objectify).  Because it is an existing webapp, I
can't start from scratch using the SDK's example project.

  I struggle to configure the application correctly.  That is,
which libraries to add to the project and where?  What has to be
added to the development classpath (for compilation) and what has
to be added to the WAR itself?

  Any clue and/or article?

  Thank you, regards,

[google-appengine] File downloading to GAE Servers

[Webhoundx]

Hi,

Is it possible to download a file hosted on another server to GAE
server?
For example if you visit,
http://www.cse.lk/listedcompanies/overview.htm?d-16544-e=1&6578706f7274=1

You will be prompted to save a csv file on the local machine. I would
like to make a copy of this file everyday at a certain time on the GAE
server.
I'm a total newbie and really appreciate some directions.

Thanks in advance
webhoundx

[google-appengine] Mailing alerts with appengine

[Michal Makarewicz]

A have a scenario where I have to send customized alerts to large
amount of users (~30k) in certain, specified beforehand, time. My main
idea was to make a cron job, which would check every minute if there
is an alert to send and if so mark this alert as queued and add task
to task queue (this would be done in transactional manner). Now I have
two available approaches:
Approach I:
Have two different queue commands:
1. Split email list into smaller chunks (I'm not sure how big, I was
thinking about ~500) and for each of them put second command on queue.
(this one will be queued in cron job)
2. Send mail for each email address in the list.
My main concern with this approach is lack of control on how many
emails will be send simultaneously and possibility that my email will
be classified as spam.

Approach II:
Just one task:
1. Send emails for predetermined number of people (again ~500)
starting from start_index add to queue the same task with start_index
+ ~500.
This approach will be slower, so is less preferable.

I have pretty much unlimited quota so that wouldn't be a problem.
Which approach is better in this situation?

[google-appengine] Re: High CPU usage and how to improve performance

[observer247]

Almost the same usage is now triggering 10times the daily cost ! Not
sure what changed as far as billing.

Checking appstats and instances.

Re: [google-appengine] Python app unstable

Yes. It worked after a while. But even the HR app was unstable yesterday for
a while. Things are looking ok now.

Now have to figure out how to migrate blobstore.

Thanks,
