The MariaDB contribution process: a step by step guide.
Inspired by my VERY long presentation on the topic at FOSDEM26 I thought I’d say a couple of words on how the contribution process works.
Contributing changes to MariaDB server is easy because it follows industry best practices: it’s using “normal” GitHub pull requests. Note that I’m working for the MariaDB Foundation. As such, “normal” for me is doing everything in the open, for everybody to see and participate. And all of the communication around the contribution (including the code […]

The Real Operational Cost of Vacuuming in PostgreSQL
There was a time when PostgreSQL’s own developers were far more open about the real cost of their MVCC design. Back in the 8.1 era, the documentation spelled out the resource drain, the vacuum overhead, and the “cold comfort” of wraparound risk in plain language. I first read that line in 2003, and it stuck with me for more than twenty years. I could not imagine any serious operations team wanting a database that required a separate background process to […]

New binlog implementation in MariaDB 12.3
I have recently completed a large project to implement a new improved binlog format for MariaDB. The result will be available shortly in the upcoming MariaDB 12.3.1 release.
In this article, I will give a short overview of the new binlog implementation. For more details, check the documentation which is in the source tree as the file Docs/replication/binlog.md, or here: https://github.com/MariaDB/server/blob/knielsen_binlog_in_engine/Docs/replication/binlog.md
EDIT: Also see Mark Callaghan’s benchmark of the new feature.

DB Fiddle – SQL Database Playground – now has MariaDB
When choosing a database, many times you want to play and see what it can do to see if it’s relevant. Containers are easy, but a web page is even easier. DB Fiddle (https://www.db-fiddle.com/) has added MariaDB to its collection of databases that can be tested.
One of DB Fiddle’s strengths is its Text to DDL function, that can take a text format of a table, and create a database structure from it. I took the following paragraph of a […]

Reading the Room: What Europe’s MySQL Community Is Really Saying
FOSDEM was exciting from a MariaDB perspective for many reasons this year. For this blog, let me concentrate on one aspect: The discussions at what was called the “Summit for MySQL Community, Europe”, hosted by Percona on Monday 2 Feb 2026 at the Marriott Grand Place in central Brussels.
We got the answer key – the “Oracle examiner’s solution”
With many of my former MySQL AB colleagues leaving Oracle over the years, I certainly had a fairly good picture of […]

Why sysbench‑tpcc results on outdated hardware should not be presented as a valid OLTP vendor comparison
Benchmark results only have meaning when the workload, hardware, and methodology are clearly defined and reproducible. When those elements are unclear or incomplete, the conclusions can easily mislead readers into assuming the results represent something they do not.
That is the core issue with the recent Percona post comparing MySQL, Percona Server, and MariaDB.
This is not about disputing Percona’s numbers. Their results may be valid for their environment.
The problem is that the post presents the results in a […]
