Looking for opinions on using Objectify-appengine instead of JDO in GAE-J
I've been slowly and a bit painfully working my way up the datastore/JDO learning curve in GAE. Recently I've found a framework called Objectify that is supposed to be somewhere between the very-simple Datastore native API and the complex JDO. I've been reading up on it and it does seem attractive.
What I want to know is, if anyone has much experience with Objectify... How mature is it? Is there much of a user community? Is it ready for heavy-lifting primetime? Could it be abandoned?
There doesn't seem to be much discussion of Objectify here or on the web in general, which makes me nervous about entrusting my project to it.
Answer
I've looked into objectify a bit and wrote an initial post about it at http://borglin.net/gwt-project/ . There are actually at least 5 different low-level wrapper frameworks at this point (objectify, Twig, SimpleDS, siena, slim3).
I'm currently working on a interview-style comparison between objectify, Twig and SimpleDS together with the authors for each framework. They will answer a bunch of technical questions and I will do some code scenarios with each framework.
