RELAY2: store-and-forward inter-site messages to prevent message loss when site master crashes ---------------------------------------------------------------------------------------------- Key: JGRP-1514 URL: https://issues.jboss.org/browse/JGRP-1514 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.3 JGRP-1401 deals with crashes of the site master *within* the current site, and developed FORWARD_TO_COORD to deal with those temporary losses (a new coord will take over), to prevent message loss. *This* JIRA is about preventing message loss caused by the site master of a *remote site* crashing. The general idea is to store-and-forward a message for a certain time and/or a certain number of attempts to forward. The most frequent use case is probably that the site master of a remote site left (or crashed) and the new site master hasn't yet opened the bridge, so the message would be lost. Store-and-forward should help here. If we still cannot forward the message for a (configurable) time and/or number of tries, we'll send a SITE_UNREACHABLE message back to the original sender of the message, which will then have to deal with it.
