> _NotificationHookConsumer_ when performing graph commit can potentially encounter _JanusGraph's
PermanentLockingException_.
> JanusGraph [documentation|https://docs.janusgraph.org/basics/transactions/] details the
cases in which this exception occurs. The way past this exception is rollback, pause and replay
the data being committed.
> *Solution*
> Introduce the rollback, pause and retry mechanism in _NotificationHookConsumer_.
