We are changing the implementation of the Non-distributed Recovery Feature. Documentation will be up to date soon.
This feature bundles all available recovery techniques for the non-distributed version of Odysseus. Among other things it contains techniques for a Gap Recovery (at-most once), a Rollback Recovery (at-least-once) and a Precise Recovery (exactly once).
The recovery feature is designed to be extensible and a short manual of how to implement other recovery techniques is given here.
