[jira] [Commented] (BOOKKEEPER-506) Provide better topic release algorithm

    [ https://issues.apache.org/jira/browse/BOOKKEEPER-506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13597729#comment-13597729 ] 

Ivan Kelly commented on BOOKKEEPER-506:
---------------------------------------

The patch looks good (needed a little massaging to apply, new patch attached). However, im not sure that the checkExistence flag is necessary. What badness happens if you try to release and the topic isn't there? AFAICS, none.

> Currently time-based topic ownership release algorithm doesn't work well. A better algorithm is to release based on its traffic and the total memory usage by hub server.
