In a sense, yes - but its the result of the comparison that is "cached"

In the case you described, it is subrule generation. So either side of the

In version 3, the result of isSameAmount (ie if it was true or false) is
"cached".
Things will only be re-check
If you see the error "out of PermSpace" you can increase perm space.
Another strategy, is to build the rules, in chunks, say 1000 at a time, take
the Package object, and *then* add it to the rulebase. That may make it
easier.
You will need more then the default space on the heap for this I would

What is the extent of the performance impact caused by using predicate
expressions?
Check( amount == $amount )
or
Check( $amt : amount -> (isSameAmount($amt, $amount) )
My understanding is that once asserted the amount property will be

I just went no mail because of this. At least with Nabble, I just get one

Thanks for incorporating this fix. The good news is that it fixes that
problem.
The bad news for me is that I'm now experiencing a different problem (where

If you are using latest build from trunk (I'm not sure it already works
in MR3), you can use a simplified MVEL syntax:

There is no hard limit on rules, but you may need indeed to tune jvm
configuration to be able to handle such number of rules. Are you running out

I think I've discovered the problem. In the file Rete.java, in the method

We are using Maps (HashMaps) in our rules and the only way we have found

Hello,
I am using drools 3.0.6 for a retail customer.
We have the current problem that we can not add more than 1 rules.
After this, the system increases its memory and runs out of memory.
Is there a limit ?

You mean modifying twice inside the same rule consequence?

you have two patterns, there for you need two objects - it's a cross
product. Try using an eval instead of a predicate, then you can bind all
your variables on the first line, and eval them on the next line.
Until you move to 4.0 there is no clean way to do this.
