> Project: Kafka
> Issue Type: New Feature
> Reporter: Antony Stubbs
>
> Kafka should have an emergency retention setting for max disk used to prevent
> the broker running out of disk and partitions going off line. When this max
> is reached, Kafka could perhaps delete segments from the largest topics.
> Would have to be used with care as current behaviour is to preserve data at
> the cost of availability. This would favour availability over data retention.
> At the moment it's quite hard to reason about disk usage and Kafka as the max
> byte settings are all per partition, and the math can get complicated when
> you have lots of topics of different use cases and sizes..
