Subject [jira] [Commented] (GIRAPH-616) Decouple vertices and edges in DiskBackedPartitionStore and avoid writing back edges when the algorithm does not change topology.
Date Wed, 10 Apr 2013 18:18:15 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-616?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13628058#comment-13628058

Maja Kabiljo commented on GIRAPH-616:
-------------------------------------

Awesome results! 
If you were to try with bigger graph, maybe the variance would be smaller? Do you know where
the variance comes from?

The patch looks good to me, let's have giraph-613 figured out first, and we can commit this.

> Many algorithms work on a static graph. In these cases, when running out-of-core graph
we end up writing back the edges that have not changed since we read them. By decoupling vertices
and edges, we can write back only the freshly computed vertex values.
