I have a simple class Post { int id; ... }. I insert some number of them as
facts and then call ksession.execute(facts);
The whole drl file (except for package and import statements) is:
rule "collect"
when
$a : ArrayList(size > 0) from collect(Post());
then
System.out.println("Number of posts: " + $a.size());
System.out.println("DONE");
end
The time it takes to run is n-squared in the number of posts. For 4000, 8000,
16000, 32000, 64000 posts the time is (in 1/10 seconds):
4, 14, 56, 220, 852
Is this expected? Is there a better way for me to do the collect?
