I found the solution:
Use low-level API (help here:

I'm quite new at GAE, so I'm probably saying something silly, but for what I
read on GAE Java and GWT Application Development, I was under the impression
that GAE would generate indexes automatically except for some variable types
(blobs, text, etc) and for when we explicitly asked it not to.
thanks, now it works.

You'll want this setting:

Once you have that working, it'll be easier to fine tune for more granular

You maybe right or wrong depending on how they were defined.

Hello,
I had a situation, where I encountered an UserService returning a null User.
I can see in my logs, that the end user is logged in and performing some
operations. He waits for 10-20 seconds and performs another operation.
From the logs, I can trace that UserService returned a null User.
Hi,
I have a personal rule of thumb of 10 udpated entities / second [Ds is
made for heavy read throughput but is not so fast on writes]
The new High Replication datastore seems (not tried it personally...)
slower: 1 update per second is what is the max recommended. See
I want to set-up a compute intensive application on GAE and I would like to
know if the Task Queue is going to pose serious obstacles to reducing the
elapsed time.
I am presently running a test application (not using task queues) that takes
about 1 second (a 650 million iteration no-op loop).
Thanks Didier,
That is really helpful, but I have another question,
We have a web application, and we use GWT for this web application,
so If I need to update the entities by task queue and show it as a report
to the user.
What is the assurance that our task job get started as soon as we put
If your user starts some action that updates a lot of entities and you need
to show him soon after that action all or many of these entities then you
should probably change your entities model or user interface.

A few thoughts:
- Are you taking into consideration loading requests? These will cause
pauses which can last a few seconds.
- Have you enabled warm-up requests?
- What do your logs say are causing the 5xx errors?
- Have you looked at the logs for what may be causing the long
My 2 cents:
- queues scale up very well: I tried them with no throttle (on bucket
size) and you easily get 12-15 jvm running your computations. To my
knowledge, queues are the best way to get parallelism on GAE.
but
- data access / contention may be the issue: don't you write anything
back ? That
Your GAE logs should be able to give you more information as to whether the
pauses are within GAE, or connectivity/routing issues.
What exactly are you trying to do? 1000 JVMs seems quite excessive

It turns out the technique I described in my previous post has two issues.
1. Because only one transaction can be running at a time within a process,
and the entity used as the mutex really cannot be in the same entity group
as the primary entity, you can get into a situation where the mutex

Hi Jeff,
There's no way to distinguish based on domain in app.yaml/web.xml. You'll
need to either have the same mappings in both (but only request static files
off one of the domains) or use a servlet and serve them dynamically.
