Subject [jira] [Commented] (GIRAPH-613) Remove Writable from the interfaces implemented by Vertex
Date Tue, 09 Apr 2013 19:16:16 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-613?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13626969#comment-13626969
] 

Maja Kabiljo commented on GIRAPH-613:
-------------------------------------

That way it makes much more sense. And for now we should at least add something to Vertex
javadoc to state that only id, value and edges will be serialized, and that user should put
all the data he needs in vertexValue.

Are you already working on this out-of-core improvements and will have them ready for release
or not?

> Currently, Vertex implements Writable, meaning that we depend on the user (except for
the default implementation) on the way the graph is serialised and deserialized. This means
we cannot do certain optimisations, and the user can actually add additional stuff to Vertex
more than Value, Id, Edges and halt state. By removing this possibility (or allowing them
to extend a default implementation) we take control of this.
