-----------------------------------

             Summary: Decrease GMS join_timeout and increase xPING num_discovery_runs
                 Key: ISPN-10821
                 URL: https://issues.jboss.org/browse/ISPN-10821
             Project: Infinispan
          Issue Type: Task
          Components: Configuration
    Affects Versions: 10.0.0.CR3, 9.4.16.Final
            Reporter: Dan Berindei
            Assignee: Dan Berindei
             Fix For: 10.0.0.Final


Our default JGroups configurations have a GMS {{join_timeout="5000"}}, meaning the first node to start will always wait for 5 seconds before becoming coordinator. It should be safe to use the JGroups default of 2 seconds.

To make it even more safe, we could configure the discovery protocol's {{num_discovery_runs="3"}}, so that it makes multiple attempts to contact existing nodes during those 2 seconds of waiting. {{num_discovery_runs}} is only used for the initial discovery, so there's no danger of creating additional traffic while the node is up.
