> Key: HAMA-783
> URL: https://issues.apache.org/jira/browse/HAMA-783
> Project: Hama
> Issue Type: Improvement
> Components: graph
> Reporter: Edward J. Yoon
> Assignee: Edward J. Yoon
> Fix For: 0.7.0

> Attachments: patch.txt

>
> Currently there are ListVerticesInfo, DiskVerticesInfo and DirectMemory, but
> I personally think we have to do a big re-design of the vertices storage and
> graph job runner.
> Actually, the size of split is not so great. Maybe, 60 ~ 200MB. Hence, I
> don't think DiskVerticesInfo will be really helpful. Instead, we can use the
> Serialization like Spark.
> Update:
> 1) We also need to consider the checkpointing for Fault Tolerance,
> periodically.
> 2) If DiskVerticesInfo shows good performance, we can use just the
> DiskVerticesInfo.
