I have a similar question with global or fact (Foo is never modified)
What's more efficient beetwen :
1. rule Foo_globals
when
Foo(name != null) from fooGlobals
then
...
end
2. rule Foo_facts
when
Foo(name != null)
then
...
end
Same answer: most of the time, it is better to have it as a fact, but
sometimes, a from may be better by limiting your search space.
Again, these things are like SQL. You need to look at the whole domain
model as well as the set of your rules. The major performance optimizations
are made on
