Nitay Joffe commented on GIRAPH-524:
------------------------------------
I agree we should support other outputs, for example some edge output. The
existing VertexOutputFormat does have a vertex-centric thing to it though, so
I'm not sure we should rename it to GraphXX though? VertexOutputFormat has a
createVertexWriter which iterates for each vertex and allows you to do whatever
you want. We should also have an EdgeOutputFormat that iterates over edges and
allows output that way. Anything else we should support?
> Giraph can receive input from vertex or edge-centric data sets; its output is
> graph data, not "vertices"

> It is silly to have any of our Output format names tied to the "vertex" when
> in fact we are just outputting graph data. The output format names should
> reflect the formatting of the output, and perhaps which elements of the graph
> data you want in the output.
> Lets change those names? Then they get shorter too as a bonus.
