Jake Mannix commented on GIRAPH-28: ----------------------------------- Ok another patch coming soon for this, but good news: this is the output of the object size calculator now: (key: Primitive is what Dmitriy put in that test code, LDFD is a trivial class which extends the new LongDoubleFloatDoubleVertex class, and shows exactly the same memory as this) Tiny: 0 840 Object: 0 872 Primitive: 0 4536 LDFD: 0 4536 Tiny: 1 840 Object: 1 976 Primitive: 1 4536 LDFD: 1 4536 Tiny: 10 840 Object: 10 1912 Primitive: 10 4536 LDFD: 10 4536 Tiny: 100 2640 Object: 100 11272 Primitive: 100 4536 LDFD: 100 4536 Tiny: 1000 16080 Object: 1000 104872 Primitive: 1000 46784 LDFD: 1000 46784 Tiny: 10000 123600 Object: 10000 1040872 Primitive: 10000 302000 LDFD: 10000 302000 > Introduce new primitive-specific MutableVertex subclasses > --------------------------------------------------------- > > Key: GIRAPH-28 > URL: https://issues.apache.org/jira/browse/GIRAPH-28 > Project: Giraph > Issue Type: New Feature > Components: graph > Affects Versions: 0.70.0 > Reporter: Jake Mannix > Assignee: Jake Mannix > Attachments: GIRAPH-28.diff, GIRAPH-28.diff > > > As discussed on the list, > MutableVertex<LongWritable,DoubleWritable,FloatWritable,DoubleWritable> (for > example) could be highly optimized in its memory footprint if the vertex and > edge data were held in a form which minimized Java object usage. -- This message is automatically generated by JIRA.
