How to spread existing kafka topic partitions into more directories?
<p>By default, kafka uses one directory to keep the log. To increase performance, it is advised to mount more disks to the broker, and assign each disk to one directory then in <code>server.properties</code> enter the <code>log.dirs=</code> as a coma separated list of directories. The documentation says, that partitions will be distributed among the directories round-robin style. As I understand now, this is true for new topics.</p>

<p>I would like to distribute half of the partitions of my already created topic to a newly created <code>log.dir</code> while keeping the other half where they are - is there a supported way to do that ?</p>
