[rules-users] How to break the rules execution if one has been satisfied ??

[Nikhil S. Kulkarni]

Hi,

In rules, in a particular rule set, all the when's are executed. In technical terms, the activation is first created. For all the rules in a rule set the when condition is first evaluated and if the when condition is satisfied for any rule then the rule is marked as ready to fire. Once all the when part for all the rules are evaluated then all the ones that were marked for fire are fired.
The performance issue that if there are some 1500 rows. Hence, when the rule is fired there are 1500 when conditions that are firstly checked. And only after this the then part is fired. There is no way to break the when checks on successful satisfaction of a particular rule when.

Example:
If I have say a group of 1000 rules as mentioned below

Rule_1
Salience 1000
When
                Some_Conditions_1
Then
                Some_Actions_1

Rule_2
Salience 999
When
                Some_Conditions_2
Then
                Some_Actions_2
.
.
.
Rule_1000
Salience 1
When
                Some_Conditions_1000
Then
                Some_Actions_1000

Let's assume that Some_conditions_2 = true
Now even though I have an ordering using salience, the rule engine will still execute all the when conditions (Some_Conditions_1 .. Some_Conditions_1000)

Is it possible for me to break this when evaluation even if one has been satisfied?
