Re: [rules-users] compiled package too big
One proposal: Don't put the values to which you compare the attributes into
rules; put them into additional facts. Consider:
rule "bounds_a_1_10"
when
Fact( a >= 1 && <= 10 )
then ... end
and similar for 11:100, 101:1000,... could be handled by a single rule and
a set of Limit-type facts:
rule "bounds_a"
when
Limit( ?low : low, ?high : high, ?x : x )
Fact( a >= ?low && <= ?high )
then
// enact consequence, parameterized with ?x
end

Hello,
I'm using drools 4.0.7. I have excel with about 4000 rows. After compiling
it, the final Package is about 30 MB. And that's only one sheet, I have 3 of
them. Total size is about 60MB. It's too big to hold it in memory, but too
slow to read it from a file or database every time. Is there any chance to
make the package smaller. It's always the same rule, just different values
of attributes (that's why we use excel) and I think, after compilation there
are many information redundant in the package (they are repeating over and
over for every row / rule.
Do you have any solution how to solve this. It's a tariffication algorithm,
and the response must be quick. Executing is not a problem, just how to
store this big package.
Thank you
Martin
