Hard to say without knowing how many customers that query is going to return... if it's under a 100 it doesn't matter. Under a 1000 it probably doesn't matter. If it's 10,000 and it's once a week, neither is going to be very fun. Keep in mind that those queries will instantiate however many objects that match... you could suck up a lot of memory... at least use the new find/block stuff. Might want to look into ar_mailer (ruby stuff), bulk_mailer (stand alone) and if your volume is high one of the companies that does this for a living so you don't have to deal with ending up on aol/msn/ yahoo's spam blacklists... -philip --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
