----------------------------------
Summary: support succinct representation of messages in
messagestores
Key: GIRAPH-912
URL: https://issues.apache.org/jira/browse/GIRAPH-912
Project: Giraph
Issue Type: Improvement
Reporter: Pavan Kumar
Assignee: Pavan Kumar
currently one-to-all messages is useful only for reducing network transfer, but
at the server side, before processingRequest, the messages are broken down into
bytearrayvertexidmessages, thus, each message is still stored as many times as
the number of vertices it is sent to.
in this task we implements two message-stores that can represent messages in a
very succinct way
especially useful when messages are of significant size & fanout is low [note
that this is - useful only when no combiners are used]
this depends on GIRAPH-907 & GIRAPH-908
