[jira] [Commented] (KAFKA-347) change number of partitions of a topic online

    [ https://issues.apache.org/jira/browse/KAFKA-347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13554458#comment-13554458 ]

Maxime Brugidou commented on KAFKA-347:
---------------------------------------

Agreed. Except you also have to think about people not using keyed partitioning. It would be very convenient to add (maybe not remove) partitions as your topic gets larger and you increase your cluster size. And that could be done online since the number of partitions in this case is only used for scaling and distribution.

 (and I think the auto partition balancing is off-topic and I should probably open another JIRA)
