Radim Vansa commented on ISPN-2697:
-----------------------------------
Bela: I was looking on this code and just wanted do be sure I understand it correctly. The
code you posted causes one gossip to be sent in average every (desired_avg_gossip *
clusterSize) milliseconds... I don't want to compute the exact mean delay of last
gossip, but it's generally proportional to the cluster size = with big cluster, long
time.
I suppose there aren't many messages in the replicated __hotrodTopologyCache as it is
just filled from each node when it joins the cluster and then the values are not changed.
So when the size-based stability does not kick in, the seqno-based one sends stability
only every 5 minutes or more. I understand we want to save bandwidth, but this is really a
long time, most timeouts are shorter than this (like some which expects some event after
we bcast the message - not exactly the response).
Is this really desired behaviour?
HotRodServer startup fails when its record cannot be inserted into
topology cache
---------------------------------------------------------------------------------
Key: ISPN-2697
URL:
https://issues.jboss.org/browse/ISPN-2697
Project: Infinispan
Issue Type: Bug
Components: Remote protocols
Affects Versions: 5.2.0.Beta6
Reporter: Radim Vansa
Assignee: Galder ZamarreƱo
Priority: Critical
Fix For: 5.2.0.CR2
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.
