Subject [jira] [Updated] (GIRAPH-28) Introduce new primitive-specific MutableVertex subclasses
Date Mon, 12 Sep 2011 16:54:08 GMT

     [ https://issues.apache.org/jira/browse/GIRAPH-28?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jake Mannix updated GIRAPH-28:
------------------------------

    Attachment: GIRAPH-28.diff

newly regenerated patch, should apply cleanly against trunk.  Tests still pass (yay), but
still not terribly clean code.  I would argue that until we nail down the getOutpuEdgeMap()
 API, this patch should be held off on merging.  

But let's play with it more, and I think I'll turn Dmitriy's TinyVertex into another option
in here, as it's a common use-case, and even smaller still than the current primitive container
class.

> As discussed on the list, MutableVertex<LongWritable,DoubleWritable,FloatWritable,DoubleWritable>
(for example) could be highly optimized in its memory footprint if the vertex and edge data
were held in a form which minimized Java object usage.
