[rules-users] Performance consideration in rule writing
Hi, team, I have some quick questions here regarding performance best practices of rule writing. See below two pieces of rules: Rule 1 Salience 100 No-loop true When $txn : data(sourceid == 5txnjustify==995eval(creditOption($txn)==1)eval(isGCSwitch($txn))i sCurrencyEquals($txn)==0compareToPostThreshold($txn)==2); Then . End Rule 2 Salience 100 No-loop true When $txn : data(sourceid == 5txnjustify==995eval(creditOption($txn)==1)eval(isGCSwitch($txn))i sCurrencyEquals($txn)==0compareToPostThreshold($txn)==1); Then . End Questions: 1. Will I gain better performance if I put the rule differentiator condition compareToPostThreshold($txn)==2 at the beginning of both rule 1 and 2? 2. I saw salaboy's video claiming that to avoid using eval() in the rule. Do we have any alternative way to do that from a performance consideration or I'd better collect/ prepare all the data before I send them into the session? 3. What's you guys' naming convention for rule's salience? PS: my Drools version is 5.2.0.

Re: [rules-users] Problems saving BPMN2 diagrams in Guvnor
Hi Christiano, the error message says that you have a sequence flow that has no targetRef attribute. Now you could either have a dangling sequence flow or this is a bug in the designer. If you can please show a screenshot of your process before saving it or describe what node types you have there and we will try to recreate and fix. As far as no warning showing before the save - this is something that we are working on. Currently if there are issues with parsing the BPMN2 created by designer, the asset source in Guvnor is blank and that's why you are looking your process in the canvas after a save. A workaround until this is done is do click on the BPMN2 button in the designer footer which just shows the process BPMN2 before saving it. In this case you will be able to see the log errors without loosing everything on your canvas. Hope this helps.

[rules-users] 答复: Performance consideration in rule writing
Hi, Wolfgang,
I think I’ve figured out some answers and see my shares below. Thanks and
let me know your thoughts about #3.
Best
Abe
1. Will I gain better performance if I put the rule differentiator
condition “compareToPostThreshold($txn)==2” at the beginning of both rule
1 and 2?
One kind pf Rete optimization is based on evaluating common constraints
once, therefore: no.
//Abe: it definitely makes a difference if you put differentiator conditions
at the beginning �C this way RETE won’t waste efforts constructing networks
which will not fulfill. See below example.
rule Evaluation of assignment in r-value position
no-loop true
when
$statement:CStatement($value:value)
eval(Matcher.isRVExpression($value))
eval(0==Matcher.getClauseNum())
then
System.out.println($value);
modify($statement){
setSemantics(Matcher.getRVSemantics(memory,$value));
}
end
rule Evaluation of assignment clause in r-value position without updating
memory
no-loop true
when
$statement:CStatement($value:value)
eval(Matcher.isRVExpression($value))
eval(0Matcher.getClauseNum())
then
System.out.println(==+$value);
Matcher.decreaseClauseNum();
modify($statement){
setSemantics(Matcher.getRVSemanticsWithoutUpdate(memory,$value));
}
end
These two rules try to validate if Matcher.getClauseNum() ==0 or 0. If you
put differentiator “Matcher.getClauseNum()” at the end of LHS, Drools will
start two threads to deduct RETE network so even if the fact hits rule 1,
rule 2 will still be stepped in. But if we make the two rules as below, RETE
will identify the shortcut correctly and no thread will be triggered to step
into rule 2:
rule Evaluation of assignment in r-value position
no-loop true
when
eval(0==Matcher.getClauseNum())
$statement:CStatement($value:value)
eval(Matcher.isRVExpression($value))
then
System.out.println($value);
modify($statement){
setSemantics(Matcher.getRVSemantics(memory,$value));
}
end
rule Evaluation of assignment clause in r-value position without updating
memory
no-loop true
when
eval(0Matcher.getClauseNum())
$statement:CStatement($value:value)
eval(Matcher.isRVExpression($value))
then
System.out.println(==+$value);
Matcher.decreaseClauseNum();
modify($statement){
setSemantics(Matcher.getRVSemanticsWithoutUpdate(memory,$value));
}
end
2. I saw salaboy’s video claiming that to avoid using eval() in the
rule. Do we have any alternative way to do that from a performance
consideration
Constraints based on fields using == are best. Other things may result in
eval-like evaluations anyway. Most of the time, it isn't eval that causes
performance setbacks.
or I’d better collect/ prepare all the data before I send them into the
session?
Not clear what you mean by this, but if you can provide attributes that lend
themselves to straightforward constraints it might be worthwhile considering
some up-front processing of facts.
//Abe: I saw below statement from Drools document 5.2.0. As Eval is not
indexed, overuse of evale reduces the rules’ clarity and will result in a
bad performance.
5.8.3.7. Conditional Element eval
eval
Figure 5.29. eval
The conditional element eval is essentially a catch-all which allows any
semantic code (that returns a primitive boolean) to be executed. This code
can refer to variables that were bound in the LHS of the rule, and functions
in the rule package. Overuse of eval reduces the declarativeness of your
rules and can result in a poorly performing engine. While eval can be used
anywhere in the patterns, the best practice is to add it as the last
conditional element in the LHS of a rule.
Evals cannot be indexed and thus are not as efficient as Field Constraints.
However this makes them ideal for being used when functions return values
that change over time, which is not allowed within Field Constraints.
3. What’s you guys’ naming convention for rule’s salience?
Not clear what you mean by that.
//Abe: I mean how do you weight your salience values across different rules.
I’ve seen various styles in my project �C somebody uses 100, 200, 300 but
somebody uses 90, 100, 110, 120, etc. This is not a big problem as they are
working on different rules and won’t pollute each other. However I would
still try to make it consistent so maintain each other’s rule files will be
easier…

This is quite different from the rules in the original post. It is
generally not advisable to access and modify static variables, here:
clauseNum in class Matcher, i.e., not a fact.

Needlessly using eval is not good; if you have to use it you won't be
able to avoid it.

Making your rules depend on salience isn't good practice, certainly
not with more than 3 levels (my personal definition). The sort of
multi-level salience you're indicating could be an indication that
procedural style if-then-elsif logic has been fitted into rules.

1 and 2?
One kind pf Rete optimization is based on evaluating common constraints
once, therefore: no.
2. I saw salaboy’s video claiming that to avoid using eval() in the
rule. Do we have any alternative way to do that from a performance
consideration
Constraints based on fields using == are best. Other things may result in
eval-like evaluations anyway. Most of the time, it isn't eval that causes
performance setbacks.
or I’d better collect/ prepare all the data before I send them into the
session?
Not clear what you mean by this, but if you can provide attributes that lend
themselves to straightforward constraints it might be worthwhile considering
some up-front processing of facts.
3. What’s you guys’ naming convention for rule’s salience?
Not clear what you mean by that.

[rules-users] 答复: 答复: Performance consideration in rule writing
So for #1, you mean it is more from static variable safety to put uncommon
conditions at the beginning of LHS?
On #3, can you elaborate more about Making your rules depend on salience
isn't good practice ? in general, what we need to define in every rule file
is a business case, and every case stands for a flow with things like
if-elseif-else. I guess you mean I may use Drools flow or Java itself to
control the flow and leave judgment inside Drools? If that's the case, the
original concern we had was it will have too many insert() into
workingmemory which may impact performance...

This is quite different from the rules in the original post. It is generally

clauseNum in class Matcher, i.e., not a fact.

Needlessly using eval is not good; if you have to use it you won't be able
to avoid it.

they are working on different rules and won’t pollute each other.

Making your rules depend on salience isn't good practice, certainly not with
more than 3 levels (my personal definition). The sort of multi-level
salience you're indicating could be an indication that procedural style
if-then-elsif logic has been fitted into rules.

Hi, team,
I have some quick questions here regarding performance best practices
of rule writing. See below two pieces of rules:
Rule “1”
Salience 100
No-loop true
When $txn : data(sourceid == 5txnjustify==”995”
eval(creditOption($txn)==1)eval(isGCSwitch($txn))isCurrencyEqual
s($txn )==0compareToPostThreshold($txn)==2);
Then
…
End
Rule “2”
Salience 100
No-loop true
When $txn : data(sourceid == 5txnjustify==”995”
eval(creditOption($txn)==1)eval(isGCSwitch($txn))isCurrencyEqual
s($txn )==0compareToPostThreshold($txn)==1);
Then
…
End
Questions:
1. Will I gain better performance if I put the rule differentiator
condition “compareToPostThreshold($txn)==2” at the beginning of both
rule
1 and 2?

constraints once, therefore: no.

So for #1, you mean it is more from static variable safety to put uncommon
conditions at the beginning of LHS?
A static variable or a DRL global is something that must be used with
caution in a rule's LHS. In any case, if it is read, it should be used
like a constant; if you modify it, it should be used like a one-way outoing
service.
On #3, can you elaborate more about Making your rules depend on salience
isn't good practice ? in general, what we need to define in every rule
file
is a business case, and every case stands for a flow with things like
if-elseif-else. I guess you mean I may use Drools flow or Java itself to
control the flow and leave judgment inside Drools?
Think of flow (either by Drools or by Java) as a high-level progress
through application stages or phases. Salience is better restricted to
precedence within flow groups, and there I don't recommend more than three
levels.
If that's the case, the
original concern we had was it will have too many insert() into
workingmemory which may impact performance...
I don't see how one would require the other. Inserts are indicated if you
derive new facts that need to be evaluated in subsequent rules.

Hi folks, I work at a bank and I am currently studying the best way to use JBoss Rules so that it fits our needs. Our loan analysis process can take several months depending on the type of the loan. Although our business rules can evolve, a loan must follow the rules valid at the time the loan application was made. In order to attend this requirement I thought about storing at the database the name of the current snapshot with the loan application data, so that it will possible run this rules in the future without freezing my rule database. * Is there a better way to attend this requirement? * How can I retrieve meta information from a snapshot, such as the date when the snapshot was created?

@Ansgar, it looks like you are doing in a database the work that it's being done by Guvnor, that keeps a lot of meta data for all the snapshots and it's ready to keep the snapshots forever, exposing them via a service, so you applications can get the right version. In the same way that you mention just knowing the ID of the snapshot that it's required. Using Guvnor, there is no need to remove snapshots, each snapshot will only contain the rules associated with it and not a complete application.
