[jira] [Commented] (KAFKA-281) support multiple root log directories

["Taylor Gautier (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-281?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13213804#comment-13213804 ] 

Taylor Gautier commented on KAFKA-281:
--------------------------------------

I would recommend not using round-robin as that would lead to having to have some meta-data that keeps track of what directory goes where.  Hashing is easy, but the downside is that it's not trivially discoverable if a person is using a command line shell to browse the directory structure.

> Currently, the log layout is {log.dir}/topicname-partitionid and one can only specify 1 {log.dir}. This limits the # of topics we can have per broker. We can potentially support multiple directories for {log.dir} and just assign topics using hashing or round-robin.
