             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.
