Subject [jira] [Commented] (GIRAPH-57) Provide PutMsgs RPC call
Date Sat, 15 Oct 2011 00:44:11 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-57?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13128007#comment-13128007

Jakob Homan commented on GIRAPH-57:
-----------------------------------

Using a combiner will consolidate multiple messages to a single vertex, but what I'm suggesting
is to (essentially) combine multiple putMsg calls to all the vertices on a worker (after combining).
 It may be best just to build this into individual RPC mechanisms, although the current RPCCommunications
class knows more about when all the messages to a particular vertex have been {{putMsg}}ed
than do the individual proxies.

> Right now messages are sent to a vertex one at a time.  It would be good to have a putMsgs
call that could send messages to multiple vertices (all hosted on the same worker).  We'd
save a huge number of individual RPC calls at the expense of having smaller calls with larger
payloads.
