I want to run a query and receive a few keys, which I will delete afterwards. The problem is that queries return the entire entity, unnecessary work for the data store and the client (which is also reflected as slower page performance and higher bills). All I want from the query is the keys.
In SQL it would be something like select t.id from table t where t.column > someValue Is there a way to get it using the native API or in another way? I imagine that JPA will do the same if the underlying libraries can only return full records. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
