/**
 * An interface representing offset for paging. This interface is needed because various db engines
 * can have different notion of ordering and therefore it might be difficult to do paging based
 * simply on the key (of entity or attribute). Simple example is a hash map, where you cannot page
 * through the map based on the key stored in the map. This is just a labeling interface.
