    • delete vertex properties entries of non-existent vertex
    • delete vertex properties with unknown ids
    • delete edges with unknown/removed edge or vertex labels
    • delete edges that points to non-existent vertices
    • restore secondary copy of the edge if primary one exist
    • delete second copy of the edge data if primary one was deleted
