Is Galera Cluster Good?
Galera Cluster is primarily a high-availability solution and not a high-performance or scalability solution. Galera Cluster will NOT be fun if you have an unstable network. Galera Cluster is possibly not the right solution if you need very low latency or even real time behaviour.

Is there proxysql 2.0.5 for AWS Aurora?
ProxySQL 2.0.5 natively supports Galera Cluster, MySQL Replication and MySQL Group Replication. Unfortunately it does not, by default, support AWS Aurora; but there is still a workaround you can use. You may be asking yourself, why should I bother with ProxySQL when AWS provides me with an endpoint which will do the read-write split for me?
