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

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

@Dan: how do you add a flag to a message elsewhere ? Can't you do a cache.getAdvancedCache().withFlags(RSVP).put(K,V) ?
Or is this not supported going from client --> server via HotRod ?
The problem with detecting last-message-missed instances is that we can certainly do that by lowering the desired_avg_gossip time in STABLE, but then we're optimizing for a case that rarely occurs, at the expense of sending a lot of (unneeded) messages when everything is normal (99.999%).

> 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.
