I’m using kc18, and I have the same problem
I changed the sql using this variable ${env.JGROUPS_DISCOVERY_EXTERNAL_IP}
... values (?,'${env.JGROUPS_DISCOVERY_EXTERNAL_IP: 127.0.0.1}',NOW()....
and the column is now populated with the IP of the first node that starts (for each record). I expected the IP of the nodes participating to the cluster. Is the coordinator nodes that writes all the records?
