Subject [jira] [Commented] (GIRAPH-28) Introduce new primitive-specific MutableVertex subclasses
Date Tue, 13 Sep 2011 05:27:08 GMT

Jake Mannix commented on GIRAPH-28:
-----------------------------------

What do you mean by the "MutatorIterator" pattern?  Not being clear about whether it's sorted
or not?  Or forcing iterator() to always be sorted?  Or something else, about the X-Men series?

> 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.
