Subject [jira] [Commented] (GIRAPH-45) Improve the way to keep outgoing messages
Date Tue, 15 Nov 2011 22:57:51 GMT

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

It's going to be a bit complicated to store the messages on the destination worker.  You will
basically have to keep an out-of-core map.  I still think storing partitions to disk will
be easier than the messages.  You only load up the ones you are computing.  No need to worry
about ordering either, very simple out-of-core structure.

> 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.
