Edward J. Yoon updated HAMA-955:
--------------------------------
Attachment: HAMA-955_v05.patch
As you already might know, workers manage Vertex objects in serialized form to
reduce the memory usage and the strain on the garbage collector.
So, a lot of serialization and deserialization is needed for processing
vertices at every iteration. Here is the target point and this patch changes
them.
Please review and if you're fine, let's commit it.
