Some say that the best password is the one you don’t have to remember. That’s possible with MySQL, thanks to the auth_socket plugin and its MariaDB version unix_socket.

Neither of these plugins is new, and some words have been written about the auth_socket on this blog before, for example: how to change passwords in MySQL 5.7 when using plugin: auth_socket. But while reviewing what’s new with MariaDB 10.4, I saw that the unix_socket now comes installed by default and is one of the authentication methods (one of them because in MariaDB 10.4 a single user can have more than one authentication plugin, …

MySQL 8 and MySQL 5.7 Memory Consumption on Small Devices

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:

How to Build a Percona Server “Stack” on a Raspberry Pi 3+

The blog post How to Compile Percona Server for MySQL 5.7 in Raspberry Pi 3 by Walter Garcia, inspired me to create an updated install of Percona Server for the Raspberry Pi 3+.

I have included everything you need to have a complete Percona Server, ready to store data collection for your weather station, your GPS data, or any other project you can think of that would require data collection in a database.
