Thanks for the reply, Ryan. Actually, I need to apologize because the way I described my problem was incorrect. I'm seeing stale data not from queries, but from calls to the JDO function GetObjectById(). The calls are inside a transaction. Since the analogous low-level datastore access function get() is guaranteed to return strongly consistent data, I was under the impression that the same would be true for GetObjectById(). Am I perhaps wrong about this?
