Database Administration is a tough, often ungrateful job. Especially if you run a 24/7 business-critical MySQL or MariaDB deployment.
In a proxy-ed world, where do connections come from?
Database Proxies provide a single entry point into MySQL for the calling client applications. Proxies are wonderful tools to handle various situations like a master role switch to another node for maintenance, or for transparency with read and write connections. However, when the time comes to perform the switch action, all of the calling clients have been funneled through the proxy, so identification of the calling host from the database itself becomes difficult.
