<br><font size=2 face="sans-serif">Hi,</font>
<br>
<br><font size=2 face="sans-serif">I am looking to use drools where I can
have users subscribed to specific alerts. Hence for example - </font>
<br><font size=2 face="sans-serif">I can have a rule like -></font>
<br><font size=2 face="sans-serif">Rule 1 -> amount < {amount}</font>
<br>
<br><font size=2 face="sans-serif">Where {amount} is the value which the
user defines at the time of subscribing, hence the user wants to recieve
an alert when the amount in his account < {amount} that he just subscribed
to.</font>
<br>
<br><font size=2 face="sans-serif">I was trying to use the DROOLS template
feature and was even able to succesfully execute this specific scenario.
The use case I was executing is, when an event of type Rule 1 occurs ,
I get all users who are subscribed to rule 1, and then create a drl file
for all of those users with there custom data substituted as part of {amount}.
Now I fire the rules(note I have multiple rules one for each user} which
executes for this specific event and gives the required results(The above
example is just a sample example). My area of concerns are -</font>
<br>
<br><font size=2 face="sans-serif">1. Is Rule engine really the platform
I am looking at? As I dont have any complex logic , I just want to use
some component which can evaluate my Events that arrive with different
subscription rules?</font>
<br>
<br><font size=2 face="sans-serif">2. If I regenearte the drl file every
time an event arrives (I need to because every time a iff type of rule
can fire and the list of subscribers can be different as well), this would
have a performace impact as the rules are compiled and generated every
time and not really cached?</font>
<br>
<br><font size=2 face="sans-serif">Please let me know if the problem is
not clear. Any help/inputs in this regard would be highly appreciated.</font>
<br>
<br><font size=2 face="sans-serif">Thanks</font>
