Doesn't one have to worry about the primary key changing? Its a valid use-case, even if its not optimal. (If the primary key is a name, and they change the name before other rows in other tables reference that name, etc. I know one case in production like this currently.) > In mailing list, we can see sometimes reference to a refactoring of > Castor. Is this refactoring modifying this performance problem ? Maybe > Thomas Yip or a Castor Developer can give you some advice on This ? Yeah, I there is a level of refactoring going on. (So we can get polymorphic inheritance back, among other things) Currently, I'm focusing on the PostgreSQL side of castor; for performance and compatiablity. (pgsql7.2 is going to have some changes to the driver that we can take advantage of. I'm going to try to have the Castor take advantage of the driver in that area.) I've got some free-time this weekend, and I'm going to experiment in the area you have... see if I can find a solution to our problem. ===== Virtually, | "Must you shout too?"
