Subject [jira] [Commented] (GIRAPH-515) More efficient and flexible edge-based input
Date Thu, 14 Feb 2013 22:35:12 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-515?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13578763#comment-13578763

Claudio Martella commented on GIRAPH-515:
-----------------------------------------

I'm curious about the ooc edges. How does that change the way we store stuff? we'd have ooc
vertices and ooc edges separated?

> The current implementation of edge-based input using mutations is not as memory-efficient
as it could be, and also can't be used with immutable vertex classes.
> By having an ad-hoc code path for edges sent during input superstep, we can achieve both
memory efficiency and eliminate the current restriction.
