Recently we published the first part (m5, m5a, m6g) and the second part (C5, C5a, C6g) of research regarding comparing Graviton ARM with AMD and Intel CPU on AWS. We selected general-purpose EC2 instances with the same configurations (amount of vCPU in the first part). In the second part, we compared compute-optimized EC2 instances with the same conditions. The main goal was to see the trend and make a general comparison of CPU types on the AWS platform only for MySQL. We didn’t set the goal to compare the performance of different CPU types. Our expertise is in MySQL performance tuning. We share research “as is” with all scripts, and anyone interested could rerun and reproduce it.
All scripts, …

Editors and technical reviewers suggested that I cover how to configure MySQL query metrics in chapter 1 of Efficient MySQL Performance, but I deferred because it was out of scope for the book, which focuses on engineers using MySQL, not DBAs. As such, there’s only a note in chapter 1 that says: “Ask your DBA or read the MySQL manual.” But I’ll cover the topic here because that’s what this blog post series is for: behind the book.

For my presentation for the next FOSDEM MySQL Devroom, I needed to create some load.

As usual, for this task, what better than sysbench ?

The “problem” was that my system was already setup and I used OL7 on the always free Ampere compute instance on OCI.

As you may know, this is an ARM architecture (aarch64) and there was not sysbench rpm package available for this OS and architecture.

I also wanted to have sysbench compiled and linked with MySQL 8.0 libraries [1], [ …

There are plenty of articles on the Internet that tell you to setup a Galera Cluster by disabling an OS based firewall and also disabling SELinux. While we agree that this might be the fastest way to get your Galera Cluster setup, it is not necessarily good security hygiene, and we would prefer if you started 2022 with a bit more secure Galera Cluster!

What is SELinux? Is is Security-Enhanced Linux that allows administrators to allow who has more control over the system. It has permissive and enforcing mode, and is turned on by default in Red Hat Enterprise Linux and derivatives. It is important to remember that if you install Galera Cluster via a package that we provide, we have provided all the necessary contexts for it. You effectively do not have to disable SELinux to get started.

However, if you are using the rsync method for a …
