Subject [jira] [Commented] (GIRAPH-45) Improve the way to keep outgoing messages
Date Tue, 15 Nov 2011 21:49:51 GMT

Claudio Martella commented on GIRAPH-45:
----------------------------------------

I understand, so basically we go back to your first approach where it's the node who stores
the destination vertex that spills to disk.

It sounds like the simplest and most effective way to me.

> 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.
