[jira] [Updated] (HAMA-732) Investigate the usage of Apache
DirectMemory to store vertices
[ https://issues.apache.org/jira/browse/HAMA-732?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tommaso Teofili updated HAMA-732:
---------------------------------
Attachment: HAMA-732.2.patch
here's a new version of the patch which passes the tests, still needs to be tested extensively and also I'd like to move the DM integration in a separate module (so consider it a work in progress at the moment).

> 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.
