Re: [rules-users] Cost of queries

Hi All,
I'm wondering if anyone can tell me the relative performance impact of
queries. Is it just the cost of matching facts against them ( regular
caching rules apply etc.)?
The query pattern, which is injected, is the root
pattern. So it breaks
ALL joins and these will have to be calculated, although you do benefit
from the alpha (literal matching) having already been done.

Thanks,
