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

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-2697?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12750820#comment-12750820 ] 

Bela Ban commented on ISPN-2697:
--------------------------------

Galder, just use the damn flag ! :-) Others (dberindei) are using it too, so what's wrong with this ?

The alternative is to either have a NAKACK protocol which uses positive acks (like SMACK used to do it), but that won't scale for large clusters, or to use a desired_avg_gossip in STABLE that runs more frequently, but that generates more traffic in large clusters.

I'll look into the latter solution in JGRP-1570, and possibly come up with a STABLE2 as described in that JIRA.

Until this is available, use the flag.

> 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.
