Hello everybody ! I am using appengine for a personal project in order to create a professional application. I find Appengine really powerful but i do not understand why the new table inheritance strategy is not available even if it would not be really efficient. In the documentation it is said that the new table strategy may cause efficiency troubles due to the non supported join queries. But in concrete development if we need to store an inherited object using multiple tables due to the hierarchy and the sense of the application, we have to add a tier in the code to emulate the inheritance. I explain myself : I've got a server data hierarchy in a package called "models" that is synchronized with the client data hierarchy. Because of the non supported new-table strategy I had to create a "tier" in a package "entities" where I implemented all my persistable entities without inheritance. When an operation needs to access the stored datas, the models objects play with the entities to retrieve the needed datas and reassemble them so that the client app can ignore this kind of operation and have its development perennial.
I assume that it is really not beautiful but I still not understand why the new-table is not available even if it "would require a remote procedure call for each level of inheritance", because in the hand this is what we have to do when we are needing the new-table strategy, and in the other hand it could be a temporary implementation while waiting for the join queries.
