MySQL Load Balancers - MaxScale, ProxySQL, HAProxy, MySQL Router & nginx - a close-up look

Load balancing MySQL connections and queries using HAProxy has been popular in the past years. Recently however, we have seen the arrival of MaxScale, MySQL Router, ProxySQL and now also Nginx as a reverse proxy.For which use cases do you use them and how well do they integrate in your environment? This session aims to give a solid grounding in load balancer technologies for MySQL and MariaDB. We will review the main open-source options available: from application connectors (php-mysqlnd, jdbc), TCP reverse proxies (HAProxy, Keepalived, Nginx) and SQL-aware load balancers (MaxScale, ProxySQL, MySQL Router) and take a look into the best practices for backend health checks to ensure load balanced connections are routed to the correct nodes in several MySQL clustering topologies. You'll gain a good understanding of how the different options compare, and enough knowledge to decide which ones to explore further.
