I think that you can handle this by creating a search index that is
composite of c.field1 and p.field2.
For example:
Child(Ancestor)
ParentChildJoin
field1 : name1
field2: aa
So, to query for a child object you only have to retrieve it using:
ListParentChildJoin joins =

I was wondering what is the best to manage a new release on App Engine.
Say for example we have a live version (default) as 1.0.0 and we make

fetching of entities.

I totally agree with you. It is very difficult to design around the
large variations in performance; more consistency would make me happy
as well.
I try to leave lot of room for latency spikes in my designs and

difficult.

won't be acknowledged in the groups either.

You should probably provide some details on the actual error from your logs,
that would help us give more informed advice. (Also java or python ?)
My guess is your startup time is the problem for the new version.
If that is the case you might want to generate a load against the new
versions,
When you make the request, do you get what you expect showing up in
your app logs? Have you added some logging calls in your application
code to make sure the code you expect is being run?
Have you used something to monitor the raw requests, so you can see
the actual headers for example? What
