How to Test MySQL Server Hostname with ProxySQL Multiplexing

Overview

While working on a MySQL Galera cluster with ProxySQL, I was in the process of testing traffic going to the MySQL nodes by using the @@hostname command to ensure which MySQL host behind the proxy the query ran on. This was important as my client is using query rules to route traffic according to the rule to either the master or the slave.  But to my surprise, I didn’t always get the result that I was expecting.  This is where ProxySQL multiplexing comes into play.

Scenario

In my scenario, I was on a test server connecting to ProxySQL which was then routing my queries to the MySQL Galera nodes.  I would connect into ProxySQL using the MySQL client.

Important note: When testing query routing with ProxySQL using comments and the MySQL client, you have to use the “-c” command line option in order for the comment to not be stripped away when running queries.  You …

How to Autoscale ProxySQL in the cloud

ProxySQL is a great tool. It’s one of the most recommended technologies in our Open Source Database practice.

Many of our clients are running it or are migrating towards it, but we’ve seen that it is pretty CPU-intensive. We’ve also seen strange behavior in the connection handling when reaching the CPU saturation point.

At this point, we noticed that the frontend_connections counter in the stats_mysql_users table was not decreasing even after the connections were no longer present at the network level. This counter is used to check the max_connections value in the mysql_users configuration table, causing frontend connections to receive a “Too many connections” error. So we determined that the key element here is to scale it properly. Obviously, all the major cloud providers can help us here as they all have features like auto-scaling groups.

Jervin Real of Percona has recently …
