One of my tasks encountered a failure and wasn't retried. I think it's
because the servlet returned a 200 response, but I don't know why it
did since the exception bubbled all the way up to the base servlet. Do
we need to explicitly return a 5xx error code in exception cases for
retries to work?
I'm seeing some entities in my data store named
__unapplied_write__entity. I couldn't find any documentation on
this. What is it?

I'm getting some very confusing behavior regarding indexes in my app.
Maybe someone can help me figure out what's going on.

my app to appspot with no issues until last week. Then, after a push,
all indexes for GameDataV1 were

PlayerGameStates inside User. You'd do this:
- Get user by key
That's it! This is really fast, so you don't have to go through doing an
unnecessary query - you just pay your cost at write time, possibly
asynchronously.

Hi All,
I want to use the low level datastore, I looked at the documentation
and it looks ... complex.

Basically, I have a client program which needs to create tables and

I'm using IdGeneratorStrategy.SEQUENCE for the primary key of a table,
but it appears AppEngine bounces between 2 different sequence
generators as I create new entries. IDs are unique, but not
monotonically increasing. It's possible I've coded something wrong,
but I'm oretty sure this is a bug.

SequenceExamplesJDO.java), it seems if I specify a named sequence and

Thanks for the input,
