Re: [appengine-java] Re: Objectify-Appengine 2.1 released, supports Partial Indexes

Re: [appengine-java] Re: Objectify-Appengine 2.1 released, supports Partial Indexes

Specifically, it's the difference between calling Entity.setProperty() or Entity.setUnindexedProperty() on the low level API. Objectify interacts with the datastore through the low level API, so there is always underlying support for features. Not necessarily in a convenient form, however. Jeff
