Gongwenzhou commented on KAFKA-5560:
------------------------------------
If it is not convenient to use the existing script to migrate the topic
replica(like kafka-reassign-partitions.sh), and it may affect the running Kafka
client, if this solution is feasible, can I create a task for this improvement
item?
> LogManager should be able to create new logs based on free disk space

> Key: KAFKA-5560
> URL: https://issues.apache.org/jira/browse/KAFKA-5560
> Project: Kafka
> Issue Type: Improvement
> Components: log
> Affects Versions: 0.11.0.0
> Reporter: huxihx
> Priority: Major
> Labels: needs-kip
>
> Currently, log manager chooses a directory configured in `log.dirs` by
> calculating the number partitions in each directory and then choosing the one
> with the fewest partitions. But in some real production scenarios where data
> volumes of partitions are not even, some disks nearly become full whereas the
> others have a lot of spaces which lead to a poor data distribution.
> We should offer a new strategy to users to have log manager honor the real
> disk free spaces and choose the directory with the most disk space. Maybe a
> new broker configuration parameter is needed, `log.directory.strategy` for
> instance. A new KIP is created to track this issue:
> https://cwiki.apache.org/confluence/display/KAFKA/KIP-178%3A+Size-based+log+directory+selection+strategy
> Does it make sense?
