> Add broker configuration to set minimum value for segment.bytes and segment.ms
> ------------------------------------------------------------------------------
>
> Key: KAFKA-7760
> URL: https://issues.apache.org/jira/browse/KAFKA-7760
> Project: Kafka
> Issue Type: Improvement
> Reporter: Badai Aqrandista
> Assignee: Dulvin Witharane
> Priority: Major
> Labels: kip, newbie
>
> If someone set segment.bytes or segment.ms at topic level to a very small
> value (e.g. segment.bytes=1000 or segment.ms=1000), Kafka will generate a
> very high number of segment files. This can bring down the whole broker due
> to hitting the maximum open file (for log) or maximum number of mmap-ed file
> (for index).
> To prevent that from happening, I would like to suggest adding two new items
> to the broker configuration:
> * min.topic.segment.bytes, defaults to 1048576: The minimum value for
> segment.bytes. When someone sets topic configuration segment.bytes to a value
> lower than this, Kafka throws an error INVALID VALUE.
> * min.topic.segment.ms, defaults to 3600000: The minimum value for
> segment.ms. When someone sets topic configuration segment.ms to a value lower
> than this, Kafka throws an error INVALID VALUE.
> Thanks
