[infinispan-issues] [JBoss JIRA] (ISPN-2697) HotRodServer startup fails when its record cannot be inserted into topology cache

[Radim Vansa (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-2697?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12745881#comment-12745881 ] 

Radim Vansa commented on ISPN-2697:
-----------------------------------

@Dan Berinder: it is not the rate of STABILITY (there's no message STABLE) which stays constant but STABLE_GOSSIP. In fact, STABILITY rate increases with increasing cluster size, and this is the period which should be guarded against sync.repl_timeout. However, I think that the period of STABILITY messages on large clusters is pretty long (do we want to set repl_timeout to 6 minutes for 64 node cluster with gossip period 5 seconds?)

> When the HotRodServer starts it inserts its record to __hotRodTopologyCache ({{HotRodServer.addSelfToTopologyView(...)}}).
> However, this put may very easily fail - as the command is broadcasted using NAKACK2 protocol, if the message gets lost and there's no following broadcasted message, the message will be not retransmitted and the put operation times out (Replication timeout), which fails the whole HotRodServer startup, all because of one lost UDP message.
