While we often run MySQL on larger scale systems in Production for Test and Dev, sometimes we want to run MySQL on the tiniest cloud instances possible or just run it on our laptops. In these cases, MySQL 8 and MySQL 5.7 memory consumption is quite important.

In comparing MySQL 8 vs MySQL 5.7, you should know that MySQL 8 uses more memory. Basic tests on a 1GB VM with MySQL 8 and MySQL 5.7 (actually they’re Percona Server versions) running the same light workload, I see the following vmstat output:

In this article, I would like to start a series of short blog posts highlighting small, often less known, but potentially useful features, available in Percona Server for MySQL. Let’s start with a relatively new feature.

Limit the disk space used by binary logs problem
