    [ https://issues.apache.org/jira/browse/KAFKA-1480?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14057656#comment-14057656 ] 

Manikumar Reddy commented on KAFKA-1480:
----------------------------------------

We have introduced "log.roll.ms" server property as part of https://issues.apache.org/jira/browse/KAFKA-1325.
This should solve this JIRA.

We already have topic-level-configs retention.ms, segment.ms at milli-second granularity.

> 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?
