[jboss-jira] [JBoss JIRA] (JGRP-1649) RELAY2: everyone can be a site master

Bela Ban created JGRP-1649: ------------------------------ Summary: RELAY2: everyone can be a site master Key: JGRP-1649 URL: https://issues.jboss.org/browse/JGRP-1649 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.4 The site master can become a bottleneck if we have a lot of traffic between sites. Also, forwarding messages to a local site master and the site master of the target site forwarding messages to the final destination generates additional traffic. Therefore, allow every member to become a site master: * Every member joins the local cluster (site) *and* the global cluster ** Everyone (as a site master) maintains a routing table that consists of target sites ("sfo") and a list of site masters * When a message is received whose destination is SiteMaster"sfo"), we pick a random member of the list for "sfo" and relay the message to it * The target site master then receives and possibly forwards the message to the final destination (if it isn't the final dest) Not sure yet if this will be a new protocol (RELAY3) or whether RELAY2 will be enhanced. Also, investigate whether it makes sense to make only a *subset* of the site nodes site masters. This would still require local forwarding from non site masters. -- This message is automatically generated by JIRA.
