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 Fri, 15 Feb 2013 12:45:13 GMT

    [ https://issues.apache.org/jira/browse/HAMA-734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13579140#comment-13579140

Suraj Menon commented on HAMA-734:
----------------------------------

In HAMA-733 you are breaking your synchronization consistency and would need to implement
a new relaxed synchronization strategy. In this you would implement getShallowCopy and getDeepCopy
in MessageQueue and the framework would keep reference count to check whether to instantiate
a new message queue or not in the next superstep. Note that repeating this for number of supersteps
would get really costly.

> 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.
