Steven Zhen Wu commented on KAFKA-1480:
---------------------------------------
just to clarify, it's more important to have this support in per-topic config.
should we repurpose "segment.ms" for minute unit? or should we define a new
config like "segment.ms.minute"?
> support log.roll.minutes

> Steven,
> We initially set the rolling criterion based on hours to avoid too frequent
> log rolling and in turn too small segment files. For your case this may be
> reasonable to set the rolling criterion on minutes. Could you file a JIRA?
