Claudio Martella commented on GIRAPH-515:
-----------------------------------------
This is really cool. Out of curiosity: how much ram overall for the few hundred
billion edges (i'm assuming PRBenchmark)?
> More efficient and flexible edge-based input

> The current implementation of edge-based input using mutations is not as
> memory-efficient as it could be, and also can't be used with immutable vertex
> classes.
> By having an ad-hoc code path for edges sent during input superstep, we can
> achieve both memory efficiency and eliminate the current restriction.
