Hi Tom, If you have a legitimate need for having your models all descend from the same model, go for it. There is some performance impact, but it's not due to the size of the 'table'*, but rather because the PolyModel will generate more index entries, and will require the use of composite indexes in cases where a simple model may not .
* Consider that every single entity from evey single app is stored in a single Bigtable table, and you'll see why the number of entity types you use has no impact. :) -Nick Johnson --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
