Benedict commented on CASSANDRA-6572:
-------------------------------------
I wouldn't worry about the negligible amount of memory wasted storing the data
- after all, if there are no new messages to log it means the server isn't
serving any requests. A shutdown hook is probably easiest and sufficient, as a
periodic flush would also miss any messages logged between last flush and
shutdown.
