Subject [jira] [Commented] (HAMA-734) Hama Message Manager should be able to delegate the ownership of internal message queue on request for future superstep
Date Mon, 18 Feb 2013 23:09:12 GMT

    [ https://issues.apache.org/jira/browse/HAMA-734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13580886#comment-13580886
] 

Edward J. Yoon commented on HAMA-734:
-------------------------------------

I didn't look at closely -- how iterative algorithm can be implemented using superstep API
-- but as you described above, superstep API has no sync() method (maybe like pregel) and
multi supersteps should be defined in job configuration right? If we have a plan to introduce
additional types of synchronization in the future, the type of sync also should be able to
specified in job configuration.

> Get the ownership of the messagequeue, to improve performance in scenarios when a certain
set of messages in the queue is to be used in a future superstep than the current one. With
this feature, the message queue could be stored for future without having to read them in
the current superstep. The framework would initialize and create a new message queue internally.
