Drools DRL: Fewer larger rules vs many smaller rules -


i have many rule constraints can logically grouped "or". example: 3 rules "r1", "r2" , "r3". can construct single lhs as:

(r1 || r2 || r3)

or can make each of them separate rule. have no critical functional requirement doing either way since can detect grouping independently outside of drools.

i wonder if 1 way more advantageous other runtime execution perspective (performance, memory, etc.).

a disjunction @ pattern level handled 2 different rules, there's not gained or lost either way.

but maintenance , development point of view, 2 separate rules require 2 copies of right hand side, using disjunction in single rule appears preferable.

establishing binding variables used little tricky think recent versions (6.x) of drools handle satisfactorily.

note disjunctions @ constraint level should not split separate rules.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
