This is one of the scenarios that can be handled using CEP (Complex
Event Processing) - basically rule logic with some extensions to make
time based reasoning more convenient. In Drools, you have @event

establish temporal relations

Above all, realize that only facts *insert*-ed into Working Memory can
be taken into account by rules. So, first thing, insert the Event in rule
size. Then you can, basically, write a rule like this:
rule size
when
$p: RuleContext($size: getOldContext().getParent().getUsableSpace()

Is there any documentation snippet that says you can declare a fact

If not, why does this not cause an

Hi
Is it a good approach to apply rules on large data-sets ranging 100,000 to
50 million records Of course it depends upon the logic written in the rule
conditions and consequences.
Yes, it depends. And on what the consequences do. And
If you can insert one fact, you can insert many facts: just write a
loop getting the objects and calling session.insert(.).
Other decisions depend on the structure of your rule base, and what
needs to be done with the facts: can they be processed one by one or
do they all have to be together in
As you have Level with a field date, you can access that point in time in
milliseconds, using getTimeInMillis(). For the current time, you might
