I am finalizing my Percona Live talk MySQL and Vitess (and Kubernetes) at HubSpot. In this talk, I mentioned that I like that Percona is providing better MySQL with Percona Server. This comes with a little inconvenience though: with improvements, sometimes comes regression. This post is about such regression and a workaround I implemented some time ago (I should have shared it earlier). This regression is fixed in Percona Server 5.7.37-40, so this is mostly interesting for historical purposes, or if you are running a Percona Server version older than that.
