Benedict commented on CASSANDRA-7511:
-------------------------------------
Well, the special casing you want to eliminate actually had nothing to do with
if it was broken or not. It's the second special case that creates a snapshot
that _avoided_ breaking it for the 'special' case of snapshots being enabled,
and we cannot avoid different behaviour there. However if we wanted to always
flush we could simplify the code slightly.

> Commit log grows infinitely after CF truncate operation via cassandra-cli,
> regardless CF receives writes or not thereafter.
> CF's could be non-CQL Standard and Super column type. Creation of snapshots
> after truncate is turned off.
> Commit log may start grow promptly, may start grow later, on a few only or on
> all nodes at once.
> Nothing special in the system log. No idea how to reproduce.
> After rolling restart commit logs are cleared and back to normal. Just
> annoying to do rolling restart after each truncate.
