Is it possible to use Deferred Tasks outside the default queue?
I would like to setup multiple queues with different config settings.
For the Deferred Tasks a specific handler is setup at /_ah/queue/
__deferred__ so I wonder how that would work with multiple queues

Hi,
I have just started using Channel API and it look to work fine. But there
are few things i would like to know/clear/understand about my design.

Hi Andy,
My suggestion - if you're reluctant to use a 3rd party package - is at
least to read their source code (they are open source) to see how they
proceed to achieve what you want, which is also what they do.
I read most of Objectify: not that long -> approx 10K lines.
Definitely a must read
Thanks both of you. I would like to know the best practice of system design
when using low level api. Like where should I store the property type
information? I could simply use a Map to store the schema for each entity
but then a property sometimes has more than just the type but also

For me, it's still been beneficial to use a model-like class just like you
would for JDO and JPA and make all of your data store calls within these
classes, and make sure the methods that perform writes enforce the
invariants. I'm doing this in Javascript, even, and I've never had an issue

Hi Andy,
Why don't you try a 3rd party package with an intermediate level of
abstraction: they enforce types.
See Google recommandations at
http://code.google.com/appengine/docs/java/datastore/overview.html#Introducing_the_Java_Datastore
I personally use Objectify.

Hi,
I am trying to get away from JDO and now into Low Level API. I find that
the Low Level API is much more flexible except one thing. I have a
challenge on enforcing or checking data type for each entity property. So
if I don't want to hard code the data type or using reflection, how do I d

What was the fix? Or more precisely, what do we need to do in
addition to installing 1.4.3? I've got 1.4.3 and still see this

Hi,
What version of the SDK are you using? The increase to the time allocated
for backgrounds tasks only took place in v1.4 onwards. Also, there was a
bug in the development server pre version 1.4.3, which meant that the tasks
didn't have a 10 minute timeout.
Cheers,

To avoid polling, should it be possible for the task to post a message
