What a FOSDEM weekend in Brussels! This was MariaDB Foundation’s best FOSDEM ever, although it wasn’t a FOSDEM at all. Confused? Stay tuned.
A live migration from MySQL 5.7
The highlight in several respects was the live migration of the Cantamen cluster from MySQL 5.7 to MariaDB 10.11.
Currently, cantamen operates a MySQL 5.7 master-slave-replication cluster as backbone for our Carsharing system software solution “EBuS”. We are the leading provider in this market serving some 10.000 vehicles for roughly estimated 150.000 users. Three database schemas with some 550 tables fill about 412 GB of hard disk space on the 128-GB-RAM-equipped servers.

We changed our release model two years ago
A bit over two years ago, MariaDB Foundation and MariaDB plc jointly announced what we called our new Innovation Release Model. Since the end of 2021, we have gained experiences from it, some of which were aired by Sergei Golubchik last October in a MariaDB Unconference presentation called The Past, the Present and the Future of the MariaDB release model (a 23:05 long video).
We spoke about an emphasis on more frequent new features, and an increased engagement with the community through four yearly opportunities for contributors to see their code merged.

With Intel QuickAssist Technology, you can see a 5x performance in your MariaBackup compression, and lower CPU usage as well. Today I’m going to show you how.
What is Intel QuickAssist?
Nearly a decade ago, Intel released a technology called QuickAssist, which started out as a PCI-e card and then became integrated in many Xeon processes starting with the Skylake generation. QuickAssist Technology (often called QAT) is a special unit that the CPU can offload compression and encryption tasks onto.
I was lucky enough to have early access to this technology back when it was new.

It is the start of a new year, and with that brings the start of a new quarter, which means it is time for a contribution statistics update from us. I have lots of interesting data to walk you through this time, so let’s get started.
Year On Year Comparison
A good place to start would be to compare the previous year gone by with last year to see how we did. This table shows the number of organisations, contributors and commits to MariaDB Server in the last few years. The “Non-MariaDB” lines are contributors and commits by people who are not employed by MariaDB Plc or MariaDB Foundation.
