Jay Kreps commented on KAFKA-979:
---------------------------------
KAFKA-615 isn't quite suffient. We still do fsync on log roll it just is done
asynchronously. So if you have 1000 partitions and they all roll due to
time-based roll you still get a kind of I/O storm.
> Add jitter for time based rolling

> Currently, for low volume topics time based rolling happens at the same time.
> This causes a lot of IO on a typical cluster and creates back pressure. We
> need to add a jitter to prevent them from happening at the same time.
