When the PK is generated for the Child, parent information in the
child key is

I think I have found a solution to the problem.
Note: in the solution, I have assumed that there is no way I could
retrieve the key after persisting the child entity without an
additional query.
In order to achieve what I need, the key of the child entity has to be
manually created with
Sounds like a good idea. This would mean that I'm able to query users
by a skill pretty fast.
But is there a chance to query users which have a set of skills
efficient in app-engine? Or would i need to query for each skill

I am developing some application written in GWT on App Engine. I'm on
optimalization stage,
so i want to allow browsers to cache as much of static files as
