First Steps in Contributing to MariaDB

At MariaDB Day in February in Brussels, VP Engineering Vicențiu Ciurbaru delivered an inspiring presentation titled “Launch Your Open Source Career: First Steps in Contributing to MariaDB.”

In the spirit of the recent positive stats on new contributions to MariaDB, let me recap Vicentiu’s tips for anyone looking to make their first contribution. 

Contributing to MariaDB is not only about writing code—it’s about joining a vibrant community where every contribution, big or small, drives innovation. We hope newcomers can see a tangible path to getting involved.

How to start contributing? 

“Amen” statement for committing transactions

Every once in a while a truly inspiring contribution comes to us at MariaDB. Today’s timely contribution was from Sigma, and their inspiring contribution was in pull request 3937 which adds the AMEN statement for committing transactions. The need for harmonizing cultural norms with SQL standards is largely under explored aspect of engineering and here seems to be a good a place to start as any.

As described:

This pull request introduces a new statement, amen, which serves as an alternative to the traditional commit command in MariaDB. The motivation behind this change is to provide a more thematic and culturally resonant way to conclude transactions, reflecting the religious connotation of the name “MariaDB”.

MariaDB Contribution Statistics, January 2025

Here comes the Q4 2024 contributions report. The raw data which contains also statistics until today can be found on GitHub, here.

We can see some new names compared to the Q3 2024 report, with contributions from CloudLinux, NetBSD and Workato.

MariaDB Contribution Statistics, October 2024

Another quarter year has gone by, and in the world of MariaDB, it is time for another contributions report. The raw data for this report can be found on GitHub, here.

MariaDB Server contributions for from 1st January 2024 – 8th October 2024

There have been some interesting things to note here.

Start of Life for MariaDB 11.6

We normally announce releases and the end of life of releases, but today we are going to try something a little different, an announcement of “start of life”.

What does this mean?

The way we use GitHub is a little different to most projects. Instead of having a mainline and branching versions from that, MariaDB Server creates a new branch from the previous version. This is intended to happen shortly after the preview release of the previous version, but for various reasons it can come a little later. So by default, after the hypothetical version 11.7.0 is released, we will create the 11.8 branch in GitHub soon after.

How Intel helps MariaDB become even faster

There are many forums in the past couple of years where I have talked about how non-code contributions are just as important to MariaDB Server and us at the MariaDB Foundation as the code contributions I typically help with. I’ve also highlighted in the past how Intel have provided some fantastic non-code contributions. They assist us by detecting performance issues on their new and future platforms, as well guidance in finding the root cause of these issues.

The outcome: Over a million NOPM in HammerDB

Today I want to discuss some of the performance improvements that Intel has helped with, which have led to MariaDB Server achieving 1 million NOPM (new orders per minute) in the HammerDB TPROC-C test.

MariaDB Contribution Statistics, April 2024

With the first quarter of 2024 out of the way, we can take a look at the contribution statistics for the last three months. For the Foundation, this has been a very busy quarter, we have had a few big events to prepare for and attend. As well as two very large projects we are working on (Catalogs and vector indexing). This has meant that it has been difficult for us to keep up with all the wonderful contributions.

That being said, over the coming quarter we will try to rectify this and have some plans to make things better in future.

MariaDB Contribution Statistics, October 2023

We are in October, which means it has been 4 months since the last metrics report. It is, therefore, time for another quarterly metrics report (plus a bit more). The extra month was to allow for an announcement which is a prerequisite for this post, and it also means we are more or less aligned to real quarters. The major changes to this will come in the second half of this post, we have lots of additional data for pull requests. With that, let’s get started.
