[google-appengine] Re: App Datastore Update timing issue

[Sam]

Thanks much for the input and direction guys!

I'm coding it in now, so we'll see how it works out.  And yes, I had
missed the one little statement about the retrying of the transaction
until success.

Thanks again!

Re: [google-appengine] Analytics via log file?

[Robert Kluin]

Hi Mark,
  If you are really expecting to get a lot of traffic you should also
be aware that the log rolls.  So on the plus side you will not have to
worry about downloading a _huge_ file, the down side is that new
entries will overwrite old entries once the log gets to some certain
size.

  If you have a script to parse the log file and your entries have
some easily parsed form, I do not see how the size will affect you
much.

Re: [google-appengine] Re: Hoping to understand the difference between CPU Time and Datastore CPU Time

[Robert Kluin]

Greg,
  If you are having issues with long write times, there are two common
options you may consider: smaller batches and transactional tasks.

  I have some code that does batch processing, I set it up to search
for the maximum batch size that is currently succeeding.  Basically I
slowly increase my batch size until I am getting deadline exceeded
warnings then I drop back down adjust my 'growth factor' and repeat
the processes.  This seems to keep my batches running very close to
the upper limit without too many deadline exceeded exceptions.

  The other approach I have used it to offload some of the writes to
other background tasks.  I write a group of entities, then send
another handler another block of entities to write.  This has been
working well for me too.

Re: [google-appengine] Re: mysql over http

[James Jones]

Its very similar but your's will allow for use of many different types 
of databases and requires tomcat. Also is GAE specific. Mine is a little 
more lite weight and only requires a web server that has php with mysqli 
and json support. Mine can also be use by any language that do http 
requests and understands json. The down side is that it only supports 
MySQL. Just to be clear I am not knocking yours at all, just pointing 
out the difference as I understand them. Please let me know if I missed 
anything.

I have created a web service that may be similar to what you are
doing.  I use it as part of a service registry that runs on GAE and
provides a REST API used by visualizations, web UIs, command-line
scripts and other web services.

My service exposes the Google Visualizations Data Source API (http://
code.google.com/apis/visualization/documentation/dev/dsl_about.html)
as a REST web service, extending the Java library provided by Google.
I find this to be a comprehensive standard for providing read-only
access to databases.  The Google Java library outputs JSON, CSV, TSV,
HTML but it can easily be extended to provide a custom output format.

I have configured my web service to provide access to any table or
view in a MySQL database; but I've also been able to connect to other
databases with supported JDBC drivers (PostgreSQL, Derby, SqlServer),
although some of the GQL syntax is not supported by all databases
(e.g. limit, offset).

My service defines URIs of the form:  /service-name/database-name/
table-or-view-name.  It provides a simple REST API that allows users
to:
- list registered databases
- list tables (and views) within a database
- list columns (and datatypes) within a particular table (or view)
- submit queries that conform to the datasource wire protocol -
http://code.google.com/apis/visualization/documentation/dev/implementing_data_source.html

I just uploaded a standalone version that easily deploys to any J2EE
web app container (I use Apache Tomcat 6.x):
http://addama.googlecode.com/files/google-dsapi-svc.war.  You can
rename this war file.  Before you deploy it just include the following
files in the classpath ($TOMCAT_HOME/lib):
- the appropriate JDBC driver (jar file) ->  
http://dev.mysql.com/downloads/connector/j/5.0.html
- a configuration file called "google-dsapi-svc.config" containing
local database mappings in a JSON format.  For example:
 {
 locals: [
 {
 uri: "/google-dsapi-svc/demodb",
 classname: "com.mysql.jdbc.Driver",
 jdbcurl: "jdbc:mysql://hostname:port/
databasename",
 username: "username",
 password: ""
 }
 ]
 }

[google-appengine] Re: Hoping to understand the difference between CPU Time and Datastore CPU Time

[Greg Tracy]

I just started using AppStats for the first time - very nice package!
However, it didn't reveal any glaring problems. But it did help
validate my belief that I was using the memcache effectively.

I've been using the 'quota' package to find costly operations, and I
did discover a bug in my measurement. I was "starting the clock" in
the wrong spot so I have found some new areas to optimize. Will work
on that now... but I'm still not confident I can compensate for the
long write times.

Thanks!

[google-appengine] Re: Using a Second App for Testing: Pluses, Minuses, Issues

[stevep]

Thanks Ikai. I figured this would be the approach, but since this is
my first app setup, wanted some confirmation.

Might have misstated my original post a bit. Want to run a pure test
app whose data can ignored. Guess that's not really beat, but hadn't
thought it thru when I posted this.

Anyway, I'll be up an running soon. I'm not very experienced in this
area, and am a bit anxious. So many unknowns re: design decisions,
etc.

Cheers,
Steve

[google-appengine] Re: Datastore record datetime property stuck

[Daniel]

Thanks guys for fixing this.  This is actually the third time that
this has occurred for me.  The first was a couple months ago after the
big unexpected downtime, and then these two additional entities.
Unfortunately, this latest record relies upon the key name, so I
couldn't create a record of duplicate values. With my inability to
delete the record, I wouldn't have been able to free up the key name
for use in the new record. Also, this record has several dependencies,
which I could trace down and change, but I would prefer not to if at
all possible.

[google-appengine] Re: Analytics via log file?

[Greg Tracy]

When I do analytics like this, I use the task queue to generate
records in the datastore. Then I create the special admin handlers to
render the analysis tools inside the browser. It's far easier to parse
the data that way and you can access the results in real-time from
anywhere.

I'm not generating millions of records per day, but I have found this
to be effective for my projects.

[google-appengine] HELP!!!!

[ad...@dloweb.com]

I have a app engine account, which I created earlier this year, with a
gmail account.  It currently has locked me out.  Whenever I try to log
in to that account, it times out.  I have set up an account on our
google apps domain, but still cannot access the old account.  Who can
I contact regarding this issue?

Re: [google-appengine] Problem with having 1 Persistable w/array of all objects?

[Chris Copeland]

This is probably not a good idea.  What are your access pattens for this
entity?  How many accounts do you usually need to retrieve at once?  How
often is an account updated?

If you normally access just a few accounts, then you are incurring the cost
of retrieving all of them every time unnecessarily.

When you need to update an account you are incurring the cost of
deserialization/serialization for the entire list.  This will also lead to
contention when multiple users are updating their accounts.

[google-appengine] create key in type long

[Lu]

Hi, there

We can create key if the type is 'Key'.

For instance, Key key =
KeyFactory.createKey(Employee.class.getSimpleName(),
"alfred.sm...@example.com");

How about I want to assign a number(Long) as the key? It doesn't work
though, when I try.

I want to do this because when I run my application locally, the
(Long) id will keep incrementing. However, I want to reset them to
begin with 1 everytime for further stages of my applicaiton.

Thanks,
Lu

[google-appengine] Is BulkLoader dump consistent?

[Judge]

Hi!
I'm going to use BulkLoader (in --dump mode ) for backup purposes. I
wonder if I execute dump on live database (new entities are frequently
created and changed) will this dump be consistent?
I do have foreign keys between different kinds so if dump is not
executed in some sort of global transaction I'll probably have some
broken keys, will I?

If the data fetched by the get() at the first of the transaction has been
changed (by another process) when you do the put() at the end of the
transaction, then the transaction will be retried and it will do a new get
which will see the other process's changes and the process repeats.  This
isn't obvious, but it is talked about in one of the links I sent earlier.

I think Robert's example is missing a put() at the end of the transaction
function:

def txn():
ccode = CCode.all().filter('Assinged', 0)\
   .filter('ExpireDate >=', dtCompareDate)\
.filter("PartnerID", intPartnerID).get()
   if not ccode:
  # handle no ccode
   ccode.SessionID = strSessionID
   ccode.Assigned = 1
*   ccode.put()
*
 db.run_in_transaction(txn)

[google-appengine] deletePersistentAll

[Lu]

Hi, there

I am trying to delete all objects from the database but I get some
errors saying 'java.lang.String cannot be cast to
com.google.appengine.api.datastore.Text'.

Query q2 = pm.newQuery(document.class);
Collection l = (Collection) q2.execute();
pm.deletePersistentAll();

Or what is way to delete all of them?

Thanks,
Lu

Re: [google-appengine] App Datastore Update timing issue

[Chris Copeland]

I think you can handle this with a datastore transaction.  See
http://code.google.com/appengine/articles/transaction_isolation.html for
more details.

The increment_counter example at
http://code.google.com/appengine/docs/python/datastore/transactions.htmlshould
be adaptable to your example.

[google-appengine] Analytics via log file?

[Mark]

Hi,

I was looking at the discussion about analytics here:

 
http://groups.google.com/group/google-appengine/browse_thread/thread/80d40046a3202ef2/4d1cea03e7120fa2?lnk=gst&q=analytics#4d1cea03e7120fa2

I'm in the same situation - there's a few pieces of data that I'd like
to track, and storing them in the datastore is going to introduce
extra complexity to my app, eat up more of the 100 quota index limit,
etc.

I can just make specialized log statements for the events I'm
interested in, then download the log once a day and parse it to do my
analysis. I just wonder two things:

  1) Will emitting more log statements slow down my app? For example,
I log a statement everytime I serve a particular page. If millions of
people are viewing the page, will all those log statements be a
significant drain?
  2) Scalability - downloading the log once a day and parsing it - is
anyone doing this already and can speak on their experience? I'm a bit
worried that if the daily log gets really big, trying to download and
parse it each day might become unrealistic.

I'm not sure if there are any other alternatives?

Thanks

Re: [google-appengine] Problem in windows development server with form with enctype="multipart/form-data"

[Elio Scordo]

Hi Ikai, thank you for the help. The GET method is not the point, I use POST.

This simple form, for example:







  thefile = self.request.get("file")
  foo = self.request.get("foo")
  if thefile:

It can upload pictures the first time and the stop working later. On
the cloud works perfectly.

In debug mode I can see self.request.get( "file") or self.request.get(
"foo") returning void after the first time.

I found a issue opened in 2008 and closed.. It was related to form parsing.

Does anyone use file upload and window development environment?


Thanks

[google-appengine] Re: google groups is werid!

[Ian Marshall]

Did you post via a Google group discussion web page? If so, I have
noticed a delay before a new post appears in the list. This delay is
mostly a few seconds or minutes, in my experience.

[google-appengine] Re: App Engine announcement emails being marked as Phishing in Gmail

[François Masurel]

All the maintenance notification emails have been sent to my GMail
spam folder for today's downtime.

So I didn't received any, quite annoying.

Re: [google-appengine] StringListProperty() Sort Problem

[djidjadji]

You have to use basic python code

results = Example.all().filter("tags =", tagSearch).fetch(100)
results.sort(key=lambda x: x.tags.index(tagSearch))
