Hi ,
i'm trying to implement caching of rules .
in the manual there is a statement as follows :
" Typically, a rulebase would be generated and cached on first use; to save
on the continually re-generation of the Rule Base; which is expensive."
how does rule base caches rules ? is there any method to cache the rules ?
how can i implement caching in Drools in order to avoid loading rules all
the times ?

Read: Cache the rulebase (the rulebase object) with a Cache
mechanism of your choice.
AFAIK there is no dedicated caching mechanism in Drools per se.
This makes sense, otherwise the next person would look for cache
distribution, cache synchronization in a cluster. A can of worms that
should not be touched.
For example we use JBOSS TreeCache and are happy with it. This may be
overkill, simpler implementations like oscache may just be fine - all
depends on your requirements and deployment situation.
Cheers,
Ingomar

I've just been using a singleton for the moment, tossing it and
rebuilding when the rules change. Works OK.
