[jboss-jira] [JBoss JIRA] Commented: (JGRP-1250) Quality of service properties per message

Quality of service properties per message ----------------------------------------- Key: JGRP-1250 URL: https://issues.jboss.org/browse/JGRP-1250 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.0 JGroups already has the ability to bypass certain protocols, e.g. NO_FC set in a message bypasses any flow control layer. It would be nice to do this for other protocols, too, e.g. SEQUENCER, but this needs to be done in a generic fashion. What should be done is to use *properties*, e.g. +reliable-mcast, -frag, +flowcontrol, -bundling etc. Based on these flags, each protocol decides whether to handle (or not) a message. The properties should not take up *any* space in a message if not set. This can probably be generalized, ie. by annotating a protocol with the props it provides, e.g. @Reliable @ReliableUnicast UNICAST, and by having code which matches the flags in a message and decides whether or not to process the message.
