I just came across ProxySQL. I have one simple question, if I were to use ProxySQL, do I still need to set up Replication(master-slave) first for MySQL server? Because there is hostgroup(0,1) in ProxySQL which to determine which MySQL server master and slave based on the hostgroups. Or just configure in ProxySQL? Kindly clarify on which steps should I use. Thank you.

Yes, you will need an existing replication environment since ProxySQL is a proxy service. It can work with Percona XtraDB Cluster, MariaDB Galera cluster or MySQL InnoDB Cluster as well.
