Hi,
I am using the following rule
package com.demo;
import com.sample.model.Product;
import com.sample.model.Products;
import java.util.List;
import java.util.Set;
dialect "mvel"
rule "Product_0"
no-loop
when
Product(id: hlId) accumulate (e :Product(hlId == id), $sum1 : sum(e.t1) )
then
insertLogical("hid=" + id +",T1=" + $sum1);
end
I am inserting facts (Product objects) into it and firing the rules.
When i took performance stats from visual vm with JMX. got a time of
3832ms. I can you suggest if i am doing any thing wrong with this.
Regards,
Raja Sekhar

Raja,
it is not clear what you are trying to achieve.
The rule might be well written or not, we don't know your requirements.
If "id" is what it should be - an identifier - your accumulate constraint
would match a single object for each Product (the original product itself),
which looks suspicious.
I'll assume that you are doing a performance test and you are not satisfied
with the overall execution time.
The question, however, is: how many facts are you inserting? Are you firing
all rules after the insertion of each fact, or just once at the end?
Last, but not least, which version are you using?
Accumulate should be used carefully in combination with insertLogical,
since the former updates its result every time its fact collection changes.
The latter will generate a new fact, keep track of its dependencies,
and replace it when the accumulation result itself changes.
Of course, if you were inserting 100 facts, the numbers would raise
a warning, but could be reasonable for several thousands, if not
hundred thousands. Citing one of your previous emails:
"I want to test my rules with 10,000 facts to 20,000,000 facts"

Hi Davide,
I am trying to group by Hild. Here first i will get the hlld into id and
segregate the results by hild and sum the value t1
If you take an sql
select sum(t1),hlid from product group by hild
so i will get
if the data is
hlid t1
1 10
1 10
2 10
2 10
the result would be
hiid t1
1 20
2 20
Hope you understand what i am trying to do here
Regards,
Raja

Drools does not have "groupBy", the rule you have written will react to
each Product.
You need something like:
rule Acc
when
// get all Ids
accumulate( Product( $id : id ), $ids : collectSet(
$id ) )
// for each Id
$idx : String() from $ids
// accumulate the Products
accumulate( Product( id == $idx, $p : price ), $sum :
sum( $p ) )
then
System.out.println( $idx + ' : ' + $sum );
end
This is to give you an idea, for example you could split the rule in two
or use helper facts
