洪朝阳 commented on KAFKA-7760: ---------------------------- How can it get the broker config when creating a topic by using the TopicCommand class? It set min.topic.segment.bytes property when start a broker by the kafka.Kafka class. But than, how can it get this property when create a topic by the kafka.admin.TopicCommand class? Can it store this property in a public place, such as zookeeper? > 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 > 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 > Badai -- This message was sent by Atlassian JIRA (v7.6.3#76005)
