[infinispan-issues] [JBoss JIRA] (ISPN-1407) Make sure the server_list attribute of the Hot Rod Client can be updated dynamically

[ https://issues.jboss.org/browse/ISPN-1407?page=com.atlassian.jira.plugin.... ] Mircea Markus commented on ISPN-1407: ------------------------------------- So this functionality is needed in order to switch the HR clients connected to cluster A (running e.g. ISPN 5.2) to cluster B (running e.g. ISPN 5.3) when doing rolling upgrades. This involves an sys admin connecting to every client and manually updating this list. What I'm suggesting is a potentially more elegant approach to achieve this, by upgrading the HR protocol: - sys admin connects(JMX) to cluster A and marks the site as "upgraded to cluster B" - at this stage the HR endpoints on cluster A, when receiving requests from connected users, would also tell them(piggyback, same as we do with topology info) to connect to "cluster B" on next requests - this way the sys admin does not have to update the list of servers for all the users (there might be lots of them), but only update it once on the server side -- This message is automatically generated by JIRA.
