I just want to share, after 6 days, we haven’t had any issues, the Percona XtraDB “MySQL” Cluster is working properly, the Percona ProxySQL set to load-balancer is doing a great work, we are having about 4-5K statements per second on our peak hours and the Grafana/Prometheus is showing the 3 servers having very equally the amount of SQL statements.
