Hi,
Recently, I read source code of Hama on Graph API. And I have a question about
the disk-resident and memory-resident issue.
I find that there are two classes for maintaining vertices:
ListVerticesInfo.java and DiskVerticesInfo.java. The latter supports disk
operations. However, in the class of GraphJobRunner.java, the class is set as
ListVerticesInfo in the function setupFields. Thus, it seems that the version
of disk is unusable for Graph API.
Similarly, in the function of GraphJob.submit(), the version of message queue
is also set as SortedMessageQueue instead of DiskQueue.
So, for graph processing, I want to know whether Hama is a disk-resident system
or not.
Thanks,
Zhigang Wang
