Text properties were never actually lazy loaded. We only lazy loaded them to match the JDO/JPA spec. In practice, the entire entity was being read and we just weren't populating the entity. Try running AppStats - though I suspect the deserialization shouldn't be *that* slow. -- Ikai Lan

Yeah, you might want to break it up in that case. If you don't use bigChunkOfJson frequently, put it in a different object that you can generate the key for on the fly (so you can use a get by key instead of needing to use a query). -- Ikai Lan Developer Programs Engineer, Google App Engine
