[rules-users] Implementing a XOR Group between 2 rules with Drools 3 (legacy...)

[Maxim Veksler]

Hello,

It seems that Drools 3 performs better for us (at least for now...)
then Drools 4. Drools 5 was not yet tested.


I'm wondering what is the most efficient method of implementing Drools
4 activation-group[1] feature using Drools 3 ?

In my system, in order to complete the match session I'm using a
combination of 2 rules one (and only one!) of them must pass so that
the match will be successful. I would like to use a XOR between them
and give higher salience to the first rule which is a light weight
version of the second. My motivation is keep drools from evaluating
the second more complex structure of the "heavy" rule as fast as
possible.

So, to summarize - How would you guys recommend implementing the XOR
structure between 2 Multiplicative inverse rules ?


Thank you,
Maxim.
