FYI. -------- Original Message -------- Subject: [jgroups-dev] Request for comments on FORK: grabbing a private channel for communication from an existing channel Date: Fri, 09 Aug 2013 17:37:46 +0200 From: Bela Ban <belaban(a)yahoo.com&gt; To: jg-dev <javagroups-development(a)lists.sourceforge.net&gt; I wanted to solicit feedback on FORK [1]. Using FORK, one can get a private light-weight channel off of an existing channel, e.g. to send messages, create an RpcDispatcher on top etc. The forked channel is then used exclusively by the application which forks it off of the main channel, which means it will neither interfere with the main channel, nor will it see messages other than its own. A forked channel can also add protocols, these are then private to it, too. For example, an application could grab the JGroups channel from Infinispan (Cache.getAdvancedCache().getRpcManager().getTransport().getChannel()), then fork a light-weight channel with CENTRAL_LOCK on top and use it to manage cluster wide locks. The forked channel would be private to the application which creates it, but it would piggyback its messages on the existing channel, without interfering with it. I'm currently implementing a prototype, and would like to get feedback for the current design [1]. The design doc and impl are in branch JGRP-1613. Feedback on the mailing list is appreciated !
