[google-appengine] AE for a bussiness app

2008-12-09 Thread Selva

I have a road map to deploy a datasstore featured application in AE.
The main design is to store a huge amount of static data and getting
the part of the data as per the requirements. There will not be any
major data includes in production.The only issue in this is
maintaining the huge amount of data (around 1000k entities) in the
datastore , b4 that adding it to the datastore. I have completed the
full application bt I couldn't upload it b'coz of the above
limitations. Let any clarify me, Is GAE team having a clear roadmap
regarding the datastore, timeout,pricing issues?

[google-appengine] Working with a proxy for data storage and URL fetch

2008-12-01 Thread Selva

This is a situation which is completely different. I got a requirement
to store more than 15k of entities in a datastore.
I could not succeed with bulkload utility. I did a small trick for
this. I have uploaded all the data to an RDBMS and
I have  written wsgi handlers to access the db and fetch the values. I
have configured the mod_wsgi to the apache .
From the GAE application, I am calling the wsgi handlers through the
urlfetch API. Currently GAE is used as a templating language and a
platform for my application. Is this the correct solution in temporary
basis till the datastore bulkload is possible? Could you please
clarify me.

[google-appengine] bulkload issues

2008-11-20 Thread Selva

I have a requirement of loading around 50 entities to a data
model. Each entity contains max of 20 attributes.
But the no.of attributes  for each entity is varying(i.e, some records
will not have all the field values).
When I am trying to use bulkload utility to load the data.

Since the absence of some attribute values, import failure error Iam
getting.
If I use empty field bw two commas, except string type data, converter
method raises exception.

Could any body help me to overcome this issue? Any other options to
upload the huge amount of data values
to the datastore in very short time. I used the straight forward
instance creation mechanism, but after a period of 10 hr also it has
not completed.

FYI: The application is not yet been uploaded in App Engine. All the
data store have been created in in the local
   machine.
