[rules-users] Rule using accumulate

[Andres Corvetto]

Thank you for your answers.

I tried this approach (which yields much more elegant rules), but i'm afraid
it does not perform very well. 
If I insert 10000 Offers and then 1 bid, it takes too much time to execute.
If understand correctly it's because of the  "not Offer(creationTimestamp <
$ct)"  clause in the LHS, which forces a comparison of every matching Offer
against every other Offer.

The motivation for my original post was to find a way of achieving the
results of an accumulator without having to sort all the matching Offers by
creationTimestamp.
Going back to that first approach (using an accumulator), I found that
Drools feeds the accumulator with the matching Offers in reverse order (ie,
newest first, LIFO). 
Is this a natural consequence of the way facts are stored in the working
memory or is there a way of changing this behaviour (so that oldest are
feeded first, FIFO)?

Thanks again

- Andres
