Uploading Data from the Datastore

The point is this. There is a java application that uses the datastore from GAE via remote_api. It is necessary to pull out data from the datastore in batches. JDO and JPA are not used. The problem with how to implement withOffset(5) is normal, because "withOffset(5)" just throws 5 elements out of the selection, but still drags those five elements.

2. Look at backup/restore , perhaps through it you can do
