[jira] [Commented] (GIRAPH-741) DiskBackedPartitionStore doesn't work with static graphs that use an EdgeInputFormat

    [ https://issues.apache.org/jira/browse/GIRAPH-741?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13745889#comment-13745889 ] 

Claudio Martella commented on GIRAPH-741:
-----------------------------------------

this is a good catch. Maybe we should add a superstep parameter to the the PartitionStore API?

> Using the out-of-core feature in combination with a static graph that loads edges using an EdgeInputFormat doesn't seem to work. The check within DiskBackedPartitionStore.offloadPartition() that skips the edge offload doesn't seem to take into account that the edges might be loaded after the vertices are created, but before the initial loading is complete.
