Thomas Jungblut commented on HAMA-598:
--------------------------------------
In regards to memory usage, do you think it is neeeded to store the destination
peer address on every vertex?
Especially when it comes to fault tolerance where these values can change
easily.
Actually it would be better to calculate them on the fly based on the given
partitioner.
> Destination of Edge should be set according to partitionID with or without
> runtime partitioning option.
