Stephen Mallette commented on TINKERPOP-2859:
---------------------------------------------
yeah, the upgrade story on kryo isn't so good. gryo has already been removed as
an over the wire serialization format. it only remains for legacy file storage
and olap purposes. we do need a better binary format for file/olap i think. not
sure graphbinary will fit that need properly.
