I have a large object that I store using objectify. I need a list of those objects with only subset of the properties populated. How can this be done?

App Engine stores and retrieves entities as encoded Protocol Buffers. There’s no way for the underlying infrastructure to store, update, or retrieve only part of an entity, so there’s no point having a library that does this – hence Objectify, like other libraries, don’t. If you regularly need to access only part of an entity, split those fields into a separate entity.
