[rules-users] Rule to load facts with pagination

[gboro54]

Not sure if I am right but I believe he has a memory restriction which forces
him not to be able to load a full result set from a query and then feed this
objects into the engine as facts. Unless you have some complicated logic I
would probably do the loading logic outside of the rules. Feed X number of
your objects into your session, fire the rules in the session, then dispose
of the session and start all over for the next X objects.
