<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>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.<o:p></o:p></p>
<p class=MsoNormal>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. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Example:<o:p></o:p></p>
<p class=MsoNormal>If I have say a group of 1000 rules as mentioned below<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Rule_1<o:p></o:p></p>
<p class=MsoNormal>Salience 1000 <o:p></o:p></p>
<p class=MsoNormal>When<o:p></o:p></p>
<p class=MsoNormal>
Some_Conditions_1<o:p></o:p></p>
<p class=MsoNormal>Then<o:p></o:p></p>
<p class=MsoNormal>
Some_Actions_1<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Rule_2<o:p></o:p></p>
<p class=MsoNormal>Salience 999<o:p></o:p></p>
<p class=MsoNormal>When<o:p></o:p></p>
<p class=MsoNormal>
Some_Conditions_2<o:p></o:p></p>
<p class=MsoNormal>Then<o:p></o:p></p>
<p class=MsoNormal>
Some_Actions_2<o:p></o:p></p>
<p class=MsoNormal>.<o:p></o:p></p>
<p class=MsoNormal>.<o:p></o:p></p>
<p class=MsoNormal>.<o:p></o:p></p>
<p class=MsoNormal>Rule_1000<o:p></o:p></p>
<p class=MsoNormal>Salience 1<o:p></o:p></p>
<p class=MsoNormal>When<o:p></o:p></p>
<p class=MsoNormal>
Some_Conditions_1000<o:p></o:p></p>
<p class=MsoNormal>Then<o:p></o:p></p>
<p class=MsoNormal>
Some_Actions_1000<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Let’s assume that Some_conditions_2 = true<o:p></o:p></p>
<p class=MsoNormal>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)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is it possible for me to break this when evaluation even if
one has been satisfied?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks & Regards,<o:p></o:p></p>
