Jonathan Ellis commented on CASSANDRA-463:
------------------------------------------
After more thought I decided we don't want to reset the timer (as it were)
after each update: this allows a CF that grows large very slowly, or reaches a
steady state (the same keys are modified over and over) to block commitlog
purge indefinitely. Instead, set a large enough lifetime that most CFs will
flush out normally during that time and you only have to worry about catching
the stragglers.
> Make FlushPeriodInMinutes default to 60
