ProxySQL is a high-performance proxy, currently for MySQL and its forks (like Percona Server for MySQL and MariaDB). It acts as an intermediary for client requests seeking resources from the database. René Cannaò created ProxySQL for DBAs as a means of solving complex replication topology issues.
The ProxySQL 1.4.11 source and binary packages available at https://percona.com/downloads/proxysql include ProxySQL Admin – a tool, developed by Percona to configure Percona XtraDB Cluster nodes into ProxySQL. Docker images for release 1.4.11 are available as well: https://hub.docker.com/r/percona/proxysql/. You can download the original ProxySQL from https://github.com/sysown/proxysql/releases. The documentation is hosted on GitHub in the wiki format.
