Subject [jira] [Commented] (HAMA-598) Destination of Edge should be set according to partitionID with or without runtime partitioning option.
Date Wed, 27 Jun 2012 17:56:43 GMT

    [ https://issues.apache.org/jira/browse/HAMA-598?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13402402#comment-13402402

Thomas Jungblut commented on HAMA-598:
--------------------------------------

In regards to memory usage, do you think it is neeeded to store the destination peer address
on every vertex?
Especially when it comes to fault tolerance where these values can change easily.

Actually it would be better to calculate them on the fly based on the given partitioner.
