Hi,
We are evaluating Drools to replace a big legacy eligibility system in
government sector. One of the critical requirement is to have the system pull
correct rule based on a date e.g interest rate was 5% till 12/31/2010 but
changed to 6% from 1/1/2011. If we are running rules in 2010 or before,
calculation should use 5% else it should use 6%. Rules will run with a user
clicking a button and results will be shown to user so probably a
StatelessSession will be used. Something like AgendaFilters to filter rules
based on a date probably will not be very scalable since over time we'll have
lot of different temporal version of rules and all of them will have to be in
KnowledgeBase for AgendaFilter to work which will be memory intensive and
un-needed.IMHO, we should build KnowledgeBase with correct version of rules in
the first place. Any ideas or pointers?
Thanks
