Date Wed, 06 Feb 2013 13:53:12 GMT
Tommaso Teofili created HAMA-732:
------------------------------------

             Summary: Investigate the usage of Apache DirectMemory to store vertices
                 Key: HAMA-732
                 URL: https://issues.apache.org/jira/browse/HAMA-732
             Project: Hama
          Issue Type: Improvement
          Components: graph
    Affects Versions: 0.6.0
            Reporter: Tommaso Teofili
            Assignee: Tommaso Teofili
            Priority: Minor
             Fix For: 0.7.0


Since Apache DirectMemory can keep objects outside of the java heap that could help on improving
performances.

I created a simple extension implementation of VerticesInfo which uses Apache DirectMemory
CacheService instead of a List, performance seem to be improved.
