Subject [jira] [Commented] (GIRAPH-45) Improve the way to keep outgoing messages
Date Tue, 15 Nov 2011 18:49:51 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-45?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13150671#comment-13150671

Avery Ching commented on GIRAPH-45:
-----------------------------------

Given the way we process our data, I am curious about how you would do this efficiently. 
I have been thinking about spilling the partitions to disk instead since we can do it without
affecting messaging.  If there are too many messages, hopefully combiners should alleviate
this issue since they run on the client and server sides.

> As discussed in GIRAPH-12(http://goo.gl/CE32U), I think that there is a potential problem
to cause out of memory when the rate of message generation is higher than the rate of message
flush (or network bandwidth).
> To overcome this problem, we need more eager strategy for message flushing or some approach
to spill messages into disk.
