> Key: KAFKA-4504
> URL: https://issues.apache.org/jira/browse/KAFKA-4504
> Project: Kafka
> Issue Type: Improvement
> Components: documentation
> Affects Versions: 0.10.0.1
> Reporter: Justin Manchester
>
> Problem:
> Details of retention.bytes property at Topic level are not clear on how they
> impact partition size
> Business Impact:
> Users are setting retention.bytes and not seeing the desired store amount of
> data.
> Current Text:
> This configuration controls the maximum size a log can grow to before we will
> discard old log segments to free up space if we are using the "delete"
> retention policy. By default there is no size limit only a time limit.
> Proposed change:
> This configuration controls the maximum size a log can grow to before we will
> discard old log segments to free up space if we are using the "delete"
> retention policy. By default there is no size limit only a time limit.
> Please note, this is calculated as retention.bytes * number of partitions on
> the given topic for the total amount of disk space to be used.
