Re: [rules-users] Query on performance when adding/removing rules
It would perform less well, especially if you're parsing new rules and building new
rulesets with each request. But as with every performance issue, you never know for sure
until you mock up and benchmark.
But, some questions to get more detail:
Do you want the old rules to interact with the new rules? If not, it's best to create
a new rulebase and spawn sessions from that. This is especially the case if you're
doing concurrent requests against the same rulebase and don't want two sessions
sharing their new rules.
Will you reuse new rules, or are they unique with every request that adds them? (i.e.
could a subsequent request use the new rules without having to add them again?)
Can you give more details about the problem domain?
