Subject [jira] [Commented] (GIRAPH-45) Improve the way to keep outgoing messages
Date Mon, 28 Nov 2011 20:33:40 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-45?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13158734#comment-13158734

Jakob Homan commented on GIRAPH-45:
-----------------------------------

It's certainly an intriguing idea to go with something like leveldb. This is obviously an
area for lots of exploration and experimentation. As such, probably the best idea is to make
the interface pluggable and keep a good-enough Java version as default.  It's probably time
for a giraph-site.xml file to track these configuration possibilities.

> 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.
> The below link is Dmitriy's suggestion.
