Maja Kabiljo created GIRAPH-1085: ------------------------------------ Summary: Add InMemoryDataAccessor Key: GIRAPH-1085 URL: https://issues.apache.org/jira/browse/GIRAPH-1085 Project: Giraph Issue Type: New Feature Reporter: Maja Kabiljo Assignee: Maja Kabiljo
When we deal with graphs which have a lot of vertices with very little total data associated with them (values + edges) we start experiencing memory problems because of too many objects created, since every vertex has multiple objects associated with it. To solve this problem, we should have a serialized partition representation (current ByteArrayPartition just keeps byte[] per vertex, not per partition). We can leverage the out-of-core infrastructure and just add data accessor which won't be backed by disk but in memory buffers. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
