If you're using Java, you could try loading a synchronized static
global object from an AppEngine database in a global static block.
This will trigger only when the servlet is first loaded by any server
and so you get both the speed of simple variables for requests without
having to call the database again for each.
For a static block, put your code inside your AbstractRobotServlet
extending class like so:
public class YourRobotServlet extends AbstractRobotServlet {
static {
//add database value retrieving code here and set your
synchronized static variables up
}
...
}
