Description

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
