In the sense that having to tell the parent that "I want these 10 DS records now" and then later "I want these 9 DS records now", resulting in the transfer of 19 records. I could say, "please delete this one record now." I.e., less to transfer. The tradeoff is whether you value the mythical property of idempotent operations (where an unintentional repeated request has no bearing) or value minimizing verbiage exchanged. Idempotent operations has appeal, but having lived through it, it's not "all that." The alternative approach means the child has to maintain state and an eye on the parent. Anyway, that's a rationale behind it. Not a judgement. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Edward Lewis NeuStar You can leave a voice message at +1-571-434-5468 There are no answers - just tradeoffs, decisions, and responses.
